In Intellij IDEA, If a Java or Groovy class has "main" method, Intellij provides an option to Run the program and it figures out the classpath based on the classpath of the module. Run <className>.main() works fine. However I want to export a Uber jar for the corresponding including all the required jars from the classpath so that I can run this program somewhere else. I did not see an option in Intellij to export the java/class as uber(fat) jar. I am not looking for a gradle/maven build script to create the jar. Checking if Intellij has an option to do this automatically.
Using Intellij Ultimate Edition 14.0.4
I think that this feature is what you are looking for:

The key step is to customize the artifact and select "select to target JAR".

I'm running unit tests in Intellij 14.1.2 with the Gradle plugin. I have external config and test data that is in environment specific in a set of directories (directory for each env). I want to load the config and data via the classpath.
In Eclipse I'd just add the env specific path to the run-config and save the config as:
'Test-XYZ-UAT1'
for example.
In intellij, it seems my application config classpath is tied to my 'module' classpath:
https://www.jetbrains.com/help/idea/2016.3/run-debug-configuration-application.html
how to add directory to classpath in an application run profile in intellij idea?
..which is bad enough but for the Gradle run configs I don't even have the option to add the module classpath.
Run/Debug Configurations window has no:
'Use classpath of mod...'
section.
Question:
How can I set the classpath of the run config when running a Gradle Task within Intellij ?
..and if someone could tell me how to get application run config specific classpaths setup that would be even better.
(please tell me I'm missing something ingenius about Intellij..)
Based on quite a bit of research and trial and error, here is the solution that works for my Kotlin based Spring Boot project.
Background:
My Spring Boot project run configuration is configured to use Run Gradle task in place of the standard IDEA build as its Before launch configuration (see screen shot below).
My Spring Boot project uses src/main/resources/application.properties for JPA and logging properties.
gradle build uses the following output directories for the build. These are the default gradle build output directories for a Kotlin project.
build/classes/kotlin/main for the main class files.
build/classes/kotlin/test for the test class files.
build/resources/main for the main resource files. This is where application.properties is copied during a build.
When I attempted to run this project inside IDEA using the run configuration above, it would fail during Spring Boot start up because it could not find application.properties inside the classpath. When I inspected the classpath used during application startup, build/resources/main was missing.
My Solution
Use the information from: Gradle Goodness: Delegate Build And Run Actions To Gradle In IntelliJ IDEA to delegate IDEA build and execution to Gradle.
When IDEA is configured to delegate build and execution to Gradle, the main and test modules should be configured as follows: On the Paths tab, select Inherit project compile output path.
I have an IDEA 2016.1 Enterprise and a Gradle 2.12 multi-module project. In one of the modules, in src/main/resources, I have a file which I would like Gradle to 'expand', here is my configuration:
processResources {
filesMatching('my.properties') {
expand(project.properties)
}
}
(I would like to expand just this single file, and just copy the rest.)
It all works fine when built on the command line, but not by default in IDEA - when I clean and build the project, the file lands in build/resources/main but the placeholders are not replaced. I have to manually invoke the Gradle processResources task using the Gradle pane in IDEA and double clicking on the task.
Is this something I should report to Jetbrains (i.e. a bug) or has anybody have it working and I should change something in my configuration?
When you build from command line, you are using gradle. However, when you build the project from intellij, by default intellij doesn't use gradle to build, but use its internal build system which doesn't understand your gradle's processResources.
One way to solve it is to check "Delegate IDE build/run actions to gradle" as shown below:
If you don't want to use gradle build in intellij, there's another workaround - add processResources as a gradle task to run after build in your "Run/Debug Configurations":
Try adding the dependency in your build.gradle file, eg.
assemble.dependsOn processResources
This should work if you have java plugin applied.
I'm trying to create an executable jar from IntelliJ.
First I got the Java Security Exception and I changed sqljdbc4-4.0 to unsigned. First problem solved.
Then I got Manifest not found. Added META-INF dir to output. Second problem solved.
Next I got the BeanCreationException (unsolved):
Caused by: org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath.
In IntelliJ it is working.
I think the resources are not in the output. (application.properties, ...)
In which way do I add the resources or where are they stored in the jar.
I'm using gradle and on the spring boot homepage are only instructions for maven.
You should use spring-boot-maven-plugin or spring-boot-gradle-plugin, depending on your preferred build system.
EDIT:
Just run ./gradlew build
I suggest to dive into this getting started guide. It clarifies a lot of stuff for beginners.
A typical Spring boot project is a Maven project or a Gradle-Project (I only know how to do it with Maven, for Gradle see [luboskrnacs answer][1]). So you just need to run the maven targetpackageand pick the jar form the (created)target` folder
use a shell, go to the project root directory (where the pom.xml file is) and type
mvn clean package
cd target
the there is the xxx.jar file.
When writing Gradle scripts for my Java project, specifically, when writing build.gradle files, IntelliJ does not recognize the Gradle API.
For instance, Gradle methods calls like apply, dependencies configure appear with a black line under them and it is not possible to navigate to method declarations, there is no auto-completion etc.
I managed to work around this by adding compile gradleApi() to the build's dependencies block. However, I don't want to have this explicit dependency in my code.
I tried editing IntelliJ's project structure and add a dependency on a Gradle library (tried gradle-core and gradle-all) to my modules, but that seems to have no effect.
Is there a way to make IntelliJ associate all build.gradle files with the Gadle sources?
I solved this problem as follows:
As mention in already posted answers, configure gradle
update gradle/wrapper/gradle-wrapper.properties file
change bin to all in distributionUrl i.e.
distributionUrl=https\://services.gradle.org/distributions/gradle-6.8.3-bin.zip
to
distributionUrl=https\://services.gradle.org/distributions/gradle-6.8.3-all.zip
OR
[optional] If you are using old version of gradle wrapper and wanted to upgrade, then execute
./gradlew wrapper --gradle-version 6.8.3 --distribution-type all
Update gradle task (if present in build file)
wrapper {
gradleVersion = '6.8.3'
distributionType = Wrapper.DistributionType.ALL
}
Before importing the project to IntelliJ-Idea IDE, update build.gradle and add java and idea plugin to the plugins list
plugins {
id "java-library"
id "idea"
}
From a terminal, execute ./gradlew clean build idea or simply ./gradlew idea
Import project to IntelliJ idea.
Go to Preferences --> build,Execution,Deployment --> BuildTools --> Gradle
You can see
Restart IntelliJ idea IDE.
So above we have configured both of the options so choose either of them, except the specified location option. That's it.
Before
After
Autocomplete functionality as mentioned in this answer.
I had similar frustrations with Grails 3, which defines and runs a wrapper task when an app is created. Changing to the "all" zip in the wrapper properties file did not work because this kept getting changed back to the "bin" zip.
This was solved when it was understood that the "gradle-wrapper.properties" file simply stores the values from the "wrapper" task, and if this task is run after the properties are changed, they get changed right back.
This is easily fixed by setting some properties on the wrapper task:
wrapper.gradleVersion='3.2.1'
wrapper.distributionType=Wrapper.DistributionType.ALL
Now importing the project into IDEA gives you smart editing of your build.gradle.
when I choose build.gradle in IDEA and open it, IDE prompts
You can configure Gradle wrapper to use distribution with sources. It will provide IDE with Gradle API/DSL documentation.
I choose Ok, apply suggestion!
after project refreshing I am able to use code completion
before you import your project, configure it to use the customizable gradle wrapper as per the instructions here :-
https://docs.gradle.org/current/userguide/gradle_wrapper.html
add a task to your top level project like this:-
task wrapper(type: Wrapper) {
println "Wrapper gradleVersion = '2.12'"
gradleVersion = '2.12'
}
or whatever the latest version is.
make sure you can build the project from the gradle command line before you try importing into intelliJ, using the ./gradlew command, which will download and install a gradle distribution for you the first time you build.
set your java home, intelliJ home and gradle home variables in your machine and in intelliJ (mine look like this, yours may be different depending on your setup and your history of hacking around your machine...:-
(from .bashrc
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home
)
When you do import, choose the customisable gradle wrapper. if all is well, when you open the top level build.gradle for your project, you will be asked to configure sources for the gradle dsl, which will also update your gradle wrapper properties file to this:-
#Thu Mar 31 14:04:00 BST 2016
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.12-all.zip
.. the change being from ... bin.zip to all.zip. and that's it. This had been giving me lots of grief for a long time, but that's the way to do it. (on IntelliJ IDEA 2016.1 CE at least...)
most of this was in
Dimitry's answer too, but I couldn't get it to work using the default wrapper , it had to be the customisable wrapper.
I've started working on a large project where the IntelliJ environment has already been set up. The environment includes JUnit, and I can successfully run unit tests. I've seen screens where I can specify the usage of JUnit 3 or JUnit 4, but how can I determine which specific JUnit is being used to run my tests, e.g., JUnit 4.11?
I have already tried "Open Module Settings". When I look at the "Dependencies" tab, I don't see anything relating to JUnit, although I can run JUnit tests.
Which jar is used?
When you run JUnit from IntelliJ, the very first line of the console output displays your classpath. You can use Ctrl+F to find any "junit" references.
junit-rt.jar is a helper library that JetBrains might have written. By opening the jar as an archive with 7-zip, you will find that the only package inside it is under com.intellij
According to Java: Which of multiple resources on classpath JVM takes? the first reference to junit.jar is the one you will use.
What version is that jar?
Once you know which jar is being used, there are a number of ways to find the version. One is to use this code taken from https://stackoverflow.com/a/16729507/1405720
import junit.runner.Version;
System.out.println("JUnit version is: " + Version.id());
Another method might be to open up the jar as an archive and see if you can figure it out from there.
If you are looking for the JUnit libraries that are shipped with IntelliJ have a look at the corresponding jars in the lib/ directory of your Intellij IDEA installation.
