When there's an error in a file, IntelliJ underlines the relevant code in red and marks the position of the error in red on the right-hand side of the editor, e.g.
Is there some way that I can get a list of all errors in a module? I know IntelliJ has a "Problems" view, but I can't seem to display it, and I'm pretty sure low-level errors like this aren't shown in it anyway (IIRC it only shows project-wide problems such as missing dependencies).
In my case the module is a Grails app, so it contains both server-side (Groovy) code and front-end code (JS, HTML, CSS, etc.). If I run "Build Project" (or "Build Module") any errors in the JS code aren't listed in the output, presumably because JS code doesn't have to be built (compiled).
I'm using IntelliJ IDEA version 2018.3.3 (Ultimate Edition).
Select the module you wish to inspect in the Project pane on the left of the IDE
On the main menu, choose Analyze | Inspect Code
In the Inspection scope area, specify which files should be inspected
Click OK to run code analysis
Examine the results
Build | Build Project shows all errors in the project.

I am an Eclipse/STS user/developer, now trying to use IntelliJ Idea (CE)
2020.2.(1,2,3)
For a project based on Gradle, how spring-integration, when I open the IDE it happens the following
Ok, let the IDE load the project ... but
From above, that is the problem, I don't want that the IDE starts automatically to build/rebuild the project. I just need, open the project and that's all.
Observation: for example in Eclipse/STS exists the option to disable Build Automatically
I did do a research in the Web and I read the following posts and questions:
How to disable automatic gradle builds?
IntelliJ IDEA “Build project automatically” apparently not working
Intellij IDEA Java classes not auto compiling on save
Sadly the dialog options were changed but ...
Therefore:
From above, seems nothing to do.
Observation: from above observe the Build project automatically option is disabled
Even with that disabled and after to restart the IDE, I must always stop manually the build process
So what is missing? or Do I need a special extra plugin to accomplish my goal?
The images that you show indicate that you are building with Gradle, but the Compiler option that you disable is relevant for building projects with Idea not with Gradle.
For the 2020.2 version, you need to do the following:
Open the Setting > Build Tools page.
Disable the "Reload changes in build scripts" option.
This way you can manually control the reload. When you change the build script, you will see a small gradle icon in the right side of the editor.
For more info, refer to the IntelliJ IDEA help > Gradle section.
https://www.jetbrains.com/help/idea/work-with-gradle-projects.html#auto_reload
There are two different things in IntelliJ's Gradle support that sometimes confused: sync and build. Your pictures demonstrate sync process (note caption on the toolwindow). Word build is kind of misleading here.
What is sync? In gradle we use Groovy to define the build procedure. Groovy is an imperative programming language, so it's hard to predict resulting dependencies graph without actually executing the script. During the sync Idea executes configuration phase of gradle build (one that builds dependency graph), and obtains configured objects from the Gradle daemon. This information is used to setup project in the IDE: modules, libraries, dependencies, which sources are test, which are prod, etc.
Actual build is not happening during sync. You can convince yourself by adding syntax error to any source file, and observe that the sync succeeds. But build will fail if you invoke it.
In answer to the original question: you can't disable automatic build, because it is not enabled.
Is it possible to disable sync in Gradle project? Short answer - no. If you need a code browser, which is not required to understand all the cross-references in the source code, IDEA is not the best choice probably.
TL;DR;
Without sync IDE does not know which files are sources, and which are not. IDEA cannot open folders. It only can open projects. Good thing is that module can contain folder. So you can do the following: File | New | Project. Select Empty project, Next, select some random folder outside the source folder you want to open, Finish.
Then add new module:
Select Java in the left panel, everything else keep default, Next, Finish. Then in new module remove existing content root, and add folder with sources as new content root
Resulting project is mostly useless. Tons of red code (at least, unresolved symbols from external libraries), no inspections, no navigation, no sense. But it might be useful in some rare situations indeed.
I am trying to work through the Kotlin Koans in Intellij Idea Ultimate 2017.2 and I am having issues running the tests. I have marked the test directory as such, but when I try to run them as a whole or individually with the triangle arrow in the gutter that Intellij adds to tests I get a "No tests were found" error.
Screenshots are attached.
I have marked the test directory as such, but when I try to run them as a whole or individually with the triangle arrow in the gutter that Intellij adds to tests I get a "No tests were found" error.
You have it marked (incorrectly) as a test resource, not test source. Make sure to open the project by importing from Gradle then IDE will automatically configure the project structure and set the folders categories as needed.
I have added a Java library in the Intellij IDE, but every time I start a new Java project I can't import this library, and have to set it up over again.
This is a screenshot from Intellij Project Structure:
The library is there, but when I try to import it I get an error:
Setting up a Global Library ensures that the library is defined, however it is not automatically added as a dependency to new projects.
You must go into Project Structure -> Modules, click the Dependencies tab and press the green + to add it to your project.
Or, instead, (and if IntelliJ is smart enough) after hitting F2 to navigate to one of the compile errors in your source code, Alt-enter might allow a quick fix to add the dependency (you'd have to try it...).
I have a Scala Play project. I'm using Play 2.2.1. I downloaded Scala, Play 2 supported and SBT plugins. Everything is OK, but When I call route on Action in the Controller appear following error(Look screenshots):
I'm using IntelliJ IDEA 12.1.6 Ultimate version. Scala version 2.10.2
Anybody know how to fix this problem?
Thanks in advance!
Edit
When I generate my project to Intellij IDEA via "play idea" command in play console, and I opened project in IDEA project structure was such:
Then I saw answer #millhouse and discussing on this githup([Play 2.2] "play idea" creates not working source mapping in target) and I removed following folders from Sources Folders:
target\scala-2.10\src_managed\main\controllers
target\scala-2.10\src_managed\main\views
and "Report highlighting error" disappeared, but now there is another error:
and
my route:
And I've changed "Sources Folders" as shown below:
But it doesn't help me. And remains "Unspecified value parametrs" error.
millhouse's answer helped me find the right answer. Play 2.2 (and perhaps earlier versions, haven't checked) output a scala version of the routes file to project_dir/target/scala-2.10/src_managed/main So for IntelliJ to get the highlighting right you need to make sure that src_managed/main is added as a source folder. The reverse routes for javascript are for some reason included in project_dir/target/scala-2.10/classes_managed so you'll have to add that as well. (In your screenshot it looks like classes_managed is set to excluded so you'll want to un-exclude it by pressing the x button on the right hand side.)
Here's a screen shot of my project structure:
Update:
In Play 2.3 (or perhaps recent versions of IntelliJ) adding the classes_managed no longer fixes the problem. Instead of adding classes_managed to the project's sources add it to it's dependencies. By doing that IntelliJ should be able to pick up the compiled routes.class.
This is a common problem, it's because IntelliJ needs to be shown where to look for the compiled Scala templates and routes file. Here's how I fixed it on my IntelliJ 12.1 installation:
Go to the Module Settings for your project in IntelliJ (select the top-level, hit F4)
Choose the Modules item in the Project Structure window that appears
Select the projectname item (as opposed to the projectname-build item)
Add the compiler's output directory to the Source Folders items;
For Scala 2.10 it's target/scala-2.10/classes
I personally find the IntelliJ UI for this to be very non-intuitive; you might need to take the target directory and/or one of its subdirectories out of the Excluded Folders first
After applying that change, IntelliJ should see the results of compiling each routes and .scala.html file as just-another source file, so they won't show as "broken" and auto-complete should work for them.
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
