I already check the checkbox build project automatically in Build, Execution, Deployment > Compiler.
But in my class, even I random type some wrong keyword, no any error is shown in build output windows.
For example, I change the keyword
private Integer id
to
private2324234 Integerfdsfsfswerer id;
, press Ctrl + F9, still no any compile error is shown, why?
In auto-build window, it even show
No compilation problems found
My IntelliJ version is 2022.3.1 (Community Edition)
I have done many things and finally success, but I think the critical step is
Right-click on pom.xml and then click on "Add as Maven Project".
For more details of the origin problem, the problem occur when I select File > new > project from version control and then enter the git url.
the project is a maven project.

I'm trying to generate an artifact of my JavaFX application using Intellij but for some reason I always end up having JavaFX packager throwing an access denied error on my output directory.
Generating a simple jar works fine though.
I'm using it on Windows 8.1 with Java 8.
I had the same problem. I kind of solved it:
by ticking the "Build on make" box in the Project Structur Dialog
starting a Run of my Java App in Intellij Idea
Now the executable jar magically appeared in my build folder. God knows why.
I had this problem and solved it by deleting the Artifact from IntellIJ, then deleting the "out/artifact" previously created folder where it tried to build my jar and finally re created an artifact from scratch. For no specific reason it now worked.
I have encountered the same problem recently. I checked the permissions of the directory and can read and write. Later I deleted the artifact and re-created a new one to solve the problem. I hope to help people who have encountered this problem.
I had this problem. I ran into it because When I added artifact with + button in Project Settings->Artifacts, I selected JAR artifact , and change JAR to JavaFx Application from type drop down box on right side pane. Later, I removed this artifact and pressed + button, then selected JavaFx Application from drop down list, then it was builded successfully. My JDK version is 8.
When I call JavaVXPacker from the command line I get the following:
C:\Users\Ingo>javafxpackager -help
javafxpackager.exe has been renamed javapackager.exe.
The original file may be removed in a future release in lieu of javapackager.
Please update your scripts.
...
...
So I guess IntelliJ has to update it's script to re-enable the feature???
(using Windows 10 and JDK Liberica 15+36)
Go to File > Project Structure
Click on Artifacts on the left panel.
Thereafter click on the plus icon to add a Jar From modules with dependencies…
A pop-up will be shown and there you would have to select for the startup class of your project.
Click on OK twice to save the changes.
Lastly go to Build > Build Artifacts... And select build action.
Now your jar will be generated in the out folder of your project.

I use IntelliJ IDEA Ultimate 14 and Gradle 1.2. I manage the project from the console, but I need to debug some of the code from the IDE.
When I try to make the project, this error window appears. When I try to debug the project,
Error: Unable to make the module: idappcli, related Gradle configuration was not found.
Please, re-import the Gradle project and try again.
is written in the message window. How can I add the regular output paths to the project?
Try by opening the gradle task view and then click the refresh button. For me it solved the problem.
I also had a similar problem,
Go to : View -> Tool Windows -> Gradle.
Then press in Refresh Icon
This fixed the issue "Please, re-import the Gradle project and try again." for me (IntelliJ Ultimate 17.3.3):
(1) Detached Gradle project:
(2) Closed the project and (3) re-opened it via File > Open recent. IntelliJ will promt to import the now unlinked Gradle project. (4) Imported it and selected "Use auto-import" in the dialog.
I had the same problem with my Intellij IDEA version 2016.2 (Mac)
The solution was: In Intellij, Click on "View" then "Tool Windows" then "Gradle" then click on
I had to make sure the Use auto-import and the Use default gradle wrapper (recommended) were both checked.
File > Other Settings > Default Settings > Build, Execution, Deployment > Build Tools > Gradle
I faced the similar issue when i update my IntelliJ Idea.
To fix it i ran the below command in terminal and it fixed my problem.
gradle cleanIdea idea
For most people the refresh of Gradle that has already been suggested might solve the issue.
For the others I figured out, that deleting the .idea direcotory and reimporting the project might help.
It can be that your resources directory is not added to classpath when creating a project via Spring Initializr. So your application is never loading the application.properties file that you have configured.
To make a quick test if this is the case, add the following to your application.properties file:
server.port=8081
Now when running your application you should see in the spring boot console output something like this:
INFO o.s.b.w.e.tomcat.TomcatWebServer - Tomcat started on port(s): **8081** (http) with context path ''
If your port is still default 8080 and not changed to 8081, your application.properties files is obviously not loading.
You can also check if your application runs with gradle bootRun from command line. Which most likely will be work.
Solution:
Close IntelliJ, then inside your project folder delete the ".idea" folder
Reimport your project to IntelliJ like following: "Import Project" -> "select ONLY your build.gradle file to import". (IntelliJ will automatically grab the rest)
build and run your application again
See official answer by IntelliJ Support:
IDEA-221673
This works for me:
Close the IntelliJ Idea
Delete 'gradle' and '.gradle' folders from the project root
Start IntelliJ Idea and import the project as gradle
In my case the root cause was a missing proxy configuration. Once I configured it properly I was able to Refresh gradle projects and it finally downloaded missing files and set up the project correctly.
File > Settings > Appearance & Behaviour > System Settings > HTTP proxy
then
View > Tool Windows > Gradle
and Synchronize button
I went into the IntelliJ Gradle preferences:
Menu: Preferences > Build, Execution, Deployment > Build Tools > Gradle
And under Project Level Settings, switched the radio button to "Use default gradle wrapper (recommended)"
Hit the make button, and was in business!
#user1339 I also had the same problem. Please, read this question Building war with Gradle, Debugging with IntelliJ IDEA. It'll be very helpful for you. And recommendation for the 'Make' task. As message said, I should try to re-import the Gradle project and try again. In my case this advice became very helpful.
I recommend to try to 'Build > Rebuild Project'.
I have a groovy script I am working on, which imports dependencies using the #Grab annotation. This script will run within IDEA, and from the command line. However, within the IDE, the imports are shown in red (as unresolvable), and no auto-completion on the classes so imported is given.
I am accessing a corporate repository via a proxy, which has been configured as the Http Proxy within IDEA (the module should be, and is, in my local .m2 repo anyway!)
Anyone got any ideas (no pun intended!)?
I am using IntelliJ IDEA 12.5 Ultimate (IU-129.1135), JRE 1.7, and Groovy 2.1.6
As stated by CrazyCoder, Alt + Enter then select Grab the artifacts and Enter
There could be 2 problems interfering with the resolution of the Grab dependencies
Your source code folder has not been marked as "Sources Root". To do that, right click on the folder and select "Mark Directory As" -> "Sources Root"
Your project does not have a valid Project JDK. To do this, hit Ctrl-Alt-Shift-S, select "Project" -> "Project SDK" and give it a Java JDK.
Once these steps are done, you should be able to hit Alt + Enter and then select "Grab the artifacts"
I am a new scala user and am having problems getting a development environment functional.
I downloaded the typesafe activator which launches an editor in a web browser and was able to run the akka actor tutorial script fine.
However, I have set up my intelliJ scala/akka environment, and when copying the same sample code to intelliJ, I am getting compile errors. I have added akka 2.2-M1 via maven to my project.
Initially when I copy
import akka.actor.{ActorSystem, Props, Actor, Inbox}
the last "Inbox" library is highlighted in red, and on compile I get "Error: object Inbox is not a member of package akka.actor. It suggests that I add akka.actor.dsl.Inbox. When I do that the import is greyed out because it is "not implimented", and get a compile error further down in the script when I go to implement inbox. It says "
not found: value Inbox
val inbox = Inbox.create(system)
"
What am I doing wrong? Thanks!
I would recommend you use sbt and then use the gen-idea plugin to create your intellij project.
You'll need to re-run gen-idea every time your dependencies change - intelliJ currently won't automatically discover and resolve managed dependencies for you.
here is the plugin with directions.
https://github.com/mpeltonen/sbt-idea
also, as a professional I would recommend you use the sbt console for most of your tasks.
Ctrl-tab 0 will let you hop over there without touching your mouse.
Escape brings you back to the code editor window.
You can run sbt ~test to test on change to your files etc.
Note you may need to change focus off of intellij for it to save the file in memory if you're use ~test
I managed to resolve the same issue by adding the following library from the Maven repository
com.typesafe.akka:akka-actor_2.10:2.2-M3
to File -- Project Structure -- Libraries
In IntelliJ when I right click on a test I dont see a "Run ClassX or MethodY" anymore. In fact there is no "run" window and when I right click I cannot run any class.
It was all working fine about 3 hours ago so I am not quite sure what has changed.
IntelliJ 10.5.1 (Licensed and NOT community edition)
Java 1.6.0_24
This happens for all projects.
Update 1
I installed IDEA 11 and imported settings from 10 and then saw that it was not a free upgrade close IDEA 11 and started using IDEA 10. I am fairly certain things stopped working from that point but not sure. Is that a problem? Can I somehow delete IntelliJ configuration directory somehow and restart?
Adding a screenshot when I don't get Run option on right click:
My problem was that my test class wasn't public. I needed:
public class MyTest {
#Test
public void testMethod() {
instead of:
class MyTest {
#Test
void testMethod() {
If your project is a maven project then you can just right-click on the pom.xml file and select "add as Maven project".
This approach worked for me. (green plus third from the bottom)
I had the same problem. To fix it, I had to ensure that my class had a proper main method:
public static void main(String[] args) {
}
Every keyword in the above statement is critical. If you omit one, IntelliJ wont' recognize it. Easy-to-forget keywords are static, void, and the String[] args argument.
I had forgotten the arguments in mine ;-)
Also make sure your source code is inside a src folder which is marked as such by IntelliJ.
In my case, the cause was disabled JUnit plugin. (File — Settings — Plugins — JUnit, check, OK)
If you're using JUnit 5 (Jupiter), this happens when you use the old #Test annotation from JUnit 4. Just replace
import org.junit.Test;
with
import org.junit.jupiter.api.Test;
and IntelliJ should show the "Run" button again.
Ok after tremendous amount of eyeballing I located a {HOME}/.java directory which seemed to contain some Jetbrains related preferences. I deleted that directory plus {HOME}/.IntelliJ* directories. Then deleted all my intellij installations and downloaded it again from scratch and it now works fine..
Sigh....
Disabling gradle plugin solved the issue for me (community edition 2018.2)
In my case i right clicked the src folder and went to -> mark directory as -> sources root.
I had the same problem. I solve it by
File -> Invalidate Caches / Restart
right click on the top pom.xml -> Maven -> reimport
There should be no need to delete any configuration files.
I found that I used to have the Run option in the context menu to select either run tests or run Scala tests, etc. After I had selected an option for the first time, my options were no longer there.
I was able to resolve this issue and select the type of tests I wanted for that folder by creating a Run/Debug configuration following the instructions found in the documentation here...
https://www.jetbrains.com/help/idea/2016.1/creating-run-debug-configuration-for-tests.html?origin=old_help
As i had the same issue , i could clearly See that #Test is not providing any hint when i press control key and hover , and the same was confirmed as External Libraries was not having Gradle Dependencies added so i had to update the project as gradle project suggested by a pop up when you start Intellij.
I could resolve the issue by disabling the Gradle plugin from the Plugin menu and restart.
If the project is already added as a Maven one, unlink it.
right click on the project -> Maven -> Unlink Maven Projects
Then link it again:
right click on pom.xml -> + Add as Maven Project
I've just had the same problem and solved it in the following way.
Go to your $USER/$INTELLIJ directory e.g. $USER/.IdeaC2018.3 then find config/plugins. Rename the plugins directory and restart IntelliJ.
My guess is that the problem was caused when I upgraded IntelliJ and incompatibilities with the cucumber plugin.
For me this happened after updating Idea, and then updating all Plugins. Apparently Idea had not restarted yet. Going to File -> Settings -> Plugins and clicking 'Restart Idea' solved the problem
if you can see the play button in left side of the main function then click right click and press run.
in my case, I did not have an output folder.
file -> project structure -> under 'project' tab there's 'Project compiler output' -> define your folder.
Unfortunately, none of these worked for me. I had to
'File' -> "Invalidate Caches / Restart"
Click on pom.xml file, and then 'maven' -> "Generate Sources"
Search for pom.xml file --> Right Click on pom.xml --> Click on Add as Maven Project.
You should get a pop-up, saying downloading Mavin Plugin.
Wait till it gets completed. It takes some time depending on the number of content in pom.xml.
In the below screenshot, "BackendApp.java" is Driver Java file that contains
public static void main(String[] args){}
Right Click on such driver java file and you see Run option in green color.
I had this problem with a Kotlin project. Following action solved it:
right click on test folder -> select Mark Directory as -> choose Test Sources Root
So I had this problem on pycharm and the problem was that there was already a run configuration (in the dropdown next to the play button) that had the name of the file. When i deleted that run configuration it would create a new one that was correct.
I had the same problem and I tried all the above solutions nothing worked for me but after I install TestNG plugin it's started working since there are some TestNG annotations used in my unit tests
I had the same problem on my Intellij 2019.3 after that I updated from 2019.2.4. I thought that the problem came from the updated first, but the rollback didn't fix, so I tried de solution above e the problem was fixed. After configuring all my projects from scratch the problem get back, so I started to check everything I did. I discovered that an old project from Eclipse that uses files .launch to run and need some plugins to be able to execute on Intellij was causing the problem, after disable the following plugins the test option return.
In my case, my project is using Bazel.
The solution was to sync Bazel from Bazel plugin.
Since this is a top Google result when trying to figure out how to run a Scala project, and since for some reason IntelliJ (I'm on 2020.1.2) doesn't automatically create a run configuration for a Scala project (in contrary to a Java project), it's worth laying out the basics for future readers:
Click on "Edit Configuration" on the top right of the screen.
Inside the opened window, click the + button its top left.
Choose "Application".
Now, let's go through the required fields:
in the "Name" field, enter a name for this configuration, e.g. "run".
in the "Main Class" field, enter your main class name.
Alternatively, use the ... button to the left: inside the window that opens, click the "Project" tab, navigate to your main class, pick it and click "ok".
Note: If your main class doesn't have a main method, IntelliJ would show an alert. see listing 9 below.
Make sure the value in "Working Directory" field is correct (it should be the project folder).
in "Use classpath of module", select your module (see project vs module in IntelliJ)
That's it for configuring. Click "Apply", and close the window. Here's an example final result:
Note that my Main class is part of a package named Demo, but having a package is not necessary.
Inside the main class, make sure there's a main method.
See #Josiah Yoder answer for java, and for Scala it's:
def main(args: Array[String]): Unit = {
}
That's it. You should now have the green run and debug buttons enabled.
Seems there are version conflicts between plugins and IDEA itself that commonly break this functionality. Many of the solution here indicate people manually trying to identify the plug in, I found that to be impossible. So here is a generic way, without having to uninstall IDEA as one solution proposed:
File > Settings > Plugins > gear icon > disable all downloaded plugins
This fixed it for me.
Make sure the method is not static! JUnit only allows #Test before instance methods but Intellij doesn't complain even if you use #Test above a static method.
