I upgraded the JVM on my system from JDK 8 to JDK 11 & configured my IntelliJ IDEA (2019.1) to use it.
I am able to compile fine, but can no longer run JUnit5 tests from within the IDE.
I created a basic JUnit test:
#ExtendWith(SpringExtension.class)
class UtilsTest {
#BeforeEach
void setUp() {}
#Test
void testA {}
}
When I run this test with IntelliJ pointing to my JDK 8 install, it runs fine.
If I run this test with IntelliJ pointing to my JDK 11 install, the test fails to run & I get this error:
Unrecognized VM option 'UseSplitVerifier'
Any suggestions on how to fix this problem?
Intellij passes maven-surefire-plugin and maven-failsafe-plugin parameters to your Junit.
I got this trouble too. Even if i uncheck boxes in "Intellij -> File -> Settings -> Running Tests", doesn't work.
I removed the .idea folder and all .iml files and reimported the whole project and now, it's working.

I am working with Java source code with TestNG and frequently see errors like no test found to run OR Test event were not received whenever I try to run test cases in IntelliJ IDEA.
Which I can fix with changing Build and run using IntelliJ IDEA from Gradle.
I am looking for alternative way using which can add this somewhere as configuration instead of going and changing this manually.
You can use gradle-idea-ext-plugin to set build and run actions right in the Gradle build script:
import static org.jetbrains.gradle.ext.ActionDelegationConfig.TestRunner.CHOOSE_PER_TEST
plugins {
...
id "org.jetbrains.gradle.plugin.idea-ext" version "1.0"
...
}
idea.project.settings {
delegateActions {
delegateBuildRunToGradle = true // Delegate Run/Build to Gradle
testRunner = CHOOSE_PER_TEST // Test execution: PLATFORM, GRADLE or CHOOSE_PER_TEST
}
}
But actually, the fact that it works with IDE runner, but does not work with Gradle runner may indicate problems. I would first check if it works from the command line Gradle - make sure you run the same test with it as from the IDE. If it works in terminal but does not work in IDE, I would report a bug at YouTrack with reproducible sample.
I'm following the intelliJ IDEA tutorial titled Create your first Kotlin application

Here's my code:
fun main(args: Array<String>) {
println("What is your name?")
val name = readLine()
println("Hello $name")
}
Here's what my project structure looks like:
I notice that it says "Kotlin not configured" above my code, but when I go to Tools > Kotlin > Configure Kotlin in Project, I get
:
In the Event Log pane, I see this:

Thanks for looking!
Edit: I tried downloading JDK 15 and specifying that in my Project Structure, but I got the same results:
try build>clean project.
As for your unresolved references, you can double-click/left-click > show context options. If that doesn't work then maybe reinstall InteliJ Idea or download Android Studio which has a lot more support on google and yt.
Okay, I got it working. I'll try to figure out what I did.
tldr; I had to switch from JDK 16 to JDK 15 to get my hello world console application to run.
First, when I was setting up the project, I chose the wrong Project Template: I selected JVM - Application rather than JVM - Console Application. This is what I needed to do:
So, I started a new project, chose the right template, and I typed in my code, and I noticed a Build pane at the bottom left displayed:
I tried Build > Build Project, and nothing changed. So, I tried the Run menu item: the first section of the Run menu was grayed out, but there was another Run command in the second section of the Run menu. I selected that Run, and a little window popped up with the following:
Run
0 Edit Configurations
The "0 Edit Configurations" line was highlighted, and I got nowhere trying to figure out how to Run my code.
So, I started yet another new project, and this time I selected a different JDK, version 15:
After clicking Next, then Finish, I typed in my code, and this time the Build pane looked like the following (without me doing anything but typing in my code):
After I finished typing in my code, as the tutorial described, this time there was a little green arrow in the gutter:
When I clicked on the green arrow in the gutter, I could successfully Run my program.
So, it appears that you cannot use JDK 16, and you have to use JDK 15. intelliJ was able to detect all my installed Java versions, so any version you have installed should appear as a choice in the the project settings. You may have to quit intelliJ, then restart intelliJ after you install JDK 15 in order to see it listed as a choice under Project JDK: when you create a project.
I am running IntelliJ IDEA 2018.3.1 and am attempting test a class with the integrated test runner. The test seems to compile but not run.
This is a multi-module Maven project, and other modules have tests that run. However, I have not been able to find any differences between the projects. The surefire plugin is specifically defined on this project, and <skipTests> is specifically set to false. I have reimported the project several times in case the maven configuration is affecting the built-in runner.
The image below is the only output I get. Debug/Breakpoints will not stop.
If anyone can help or throw possibilities at me, I would appreciate it.
Edit:
Here's a simplified version of the test I'm attempting to run:
package com.jason;
// imports
#RunWith(BlockJUnit4TestRunner.class)
public class MyTest {
private ClassUnderTest clazz;
private DaoClass dao;
#Before
public void setUp() {
// using Mockito to mock the DaoClass
// injecting the DAO into the ClassUnderTest
}
#Test
public void testMethod() {
Assert.assertTrue(true);
}
}
I attempt to run the test by right-clicking on the method annotated with #Test and clicking run. The option to run the test DOES appear in the context menu. When I do so, all that appears is the screenshot.
I have attempted to do the following to troubleshoot the issue:
In the pom.xml file for the appropriate module, I have manually specified the surefire plugin in the <build><plugins> section. I then did a reimport to pick up the changes.
I have put breakpoints in the code and run the test in debug mode.
I have attempted to log output, both with an slf4j logger and a System.out.println()
I have attempted to find any differences in the IDEA .iml file between a module where the tests run and this module where the tests do not run.
I have written a very simple test class, with a method annotated with #Test and containing the line Assert.assertTrue(true)
Edit 2
Attempting to run mvn test -Dcontrollername produces the following output:
Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test (default-test) on project rma-svc: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test failed: The forked VM terminated without properly saying goodbye. VM crash or System.exit called?
Edit 3
I've updated my Maven surefire plugin to 2.22.2 and am not seeing the forked JVM issue any longer. However, running mvn test -DskipTests=false outputs No tests were executed!
I'm trying to configure Run/Debug configurations in IntelliJ (v2017.2.5) to run cucumber tests written in Groovy (v2.4) using Geb (v1.1.1) in a Gradle project. I need to use InternetExplorerDriver (v3.6)
I tried:
- Installing Cucumber for Groovy plugin and did following in Edit Configurations for IntelliJ:
Main Class: cucumber.api.cli.Main
Glue: C:\automation\Project\src\cucumber\resources\steps C:\automation\Project\src\cucumber\resources\env
Feature or folder path: C:/automation/Project/src/cucumber/features
Program Arguments: --plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvmSMFormatter --monochrome
I'm getting following error when I run/debug a feature file:
geb.driver.DriverCreationException: failed to create driver from callback 'script15077602688031015554790$_run_closure2#55d58825'
I have tried looking for solutions for similar problem on stackoverflow which suggested upgrading selenium/groovy versions (i'm using latest version
groovyVersion = '2.4'
gebVersion = '1.1.1'
seleniumVersion = '3.6.0'
I'm new to Groovy, Geb and Gradle (I know Java and Maven) hence I suspect it could be a configuration issue.
FYI, the tests run fine through commandline. I need to get debugging in intellij working.
Figured out the answer:
In my case the configuration in IntelliJ was wrong:
I used:
Main Class: cucumber.api.cli.Main
Glue: C:\automation\Project\src\cucumber\resources\steps
C:\automation\Project\src\cucumber\resources\env
Feature or folder path: C:/automation/Project/src/cucumber/features
Program Arguments: --plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvmSMFormatter --monochrome
module: Project_cucumber
Before launch: Build, Gradle task, Activate tool window:
Run Gradle task 'Project: compileCucumberGroovy'
Activate tool window [checked]
Every time I encounter this exception in IntelliJ, I fix it trivially and forget the fix easily.
Code:
package whatever;
import org.junit.Test;
public class TestClass
{
#Test
void test() {}
}
Scenario:
Add new TestClass.
Right-click TestClass.
Select "Run 'TestClass'" to run test cases.
The "Messages Build" pane shows:
Information:javac 9-ea was used to compile java sources
Information:Module "dummy" was fully rebuilt due to project configuration/dependencies changes
Information:8/16/17 11:35 PM - Compilation completed with 1 error and 0 warnings in 1s 663ms
Error:java: java.lang.ExceptionInInitializerError
What can possibly go wrong?
What are the likely issues in this simple scenario?
IntelliJ: COMMUNITY 2017.1 (idea-IC-171.4424.56)
To fix the issue, I do:
File -> Project Structure... -> Project Settings / Project -> Project SDK.
Change from "9-ea" to "1.8".
DETAILS
Apparently, the issue is discrepancies in selected JDK-s to build (java 9) and run (java 8).
I'm not sure how "9-ea" gets re-selected there for the same project - neither IntelliJ itself runs in "9-ea" JRE (according to Help -> About) nor JAVA_HOME env var is set to it nor other possible settings (like Maven -> Runner) suggest any "9-ea".
I also didn't manage to run the test under the same JDK (java 9) which it gets compiled under. However, it's unclear what JDK tests are run under because IntelliJ reports only about JDK for compilation.
If you use Lombok: For me it was a solution to set the newest version for my maven lombok dependency in the pom.xml.
*<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
<version>1.18.8</version>
</dependency>*
I was facing same error when i tried to run my application in IntelliJ-2019.2 version. Below are the steps i followed to resolve this issue.
Versions:
IntelliJ : IDEA-IntelliJ-2019.2
Java : jdk1.8_221
Go to below path in IntelliJ
File -> Project Structure -> Project -> Project SDK -> (select java version which you want to use )
(In my case under 'project SDK' java-11 was selected, I changed it to 'java8')
Click on 'Apply' and then 'OK'.
I feel I ran into this issue because IntelliJ was trying to compile my java classes using in-built java-11 whereas my java classes are built on java-8. So when i explicitly configured java-8 in IntelliJ, It worked!! Hope this helps.
I started seeing this exception once I installed Java 11 in my machine. JAVA_HOME was by default pointing to Java 11 and my project was still in Java 8. Changing JAVA_HOME to Java 8 jdk fixed the issue for me.
If you have multiple projects each running on a different JDK, use this command to temporarily change the Java version per command.
JAVA_HOME=/path/to/JVM/jdk/Home mvn clean install
If you have recently updated your IDE then you can try these steps.
Delete .idea directory for the idea project/workspace
Then go to File -> Invalidate Caches / Restart...
Once Idea is restarted re-add/import your module(s)
I faced a similar issue with JARs and Jena (while run from IntelliJ it works).
I was using Apache Jena v4.0.0 in my project and have built a JAR (with a main class for the JAR to act as a console app).
The JAR builts successfully with IntelliJ but when run throws java.lang.ExceptionInInitializerError ... Caused by: java.lang.NullPointerException. NPE suggests that something was not initialized properly.
The jar built with previous version Jena 3.17.0 works perfectly.
What I did to fix it
I've opened both the JARs, compared their META-INF folders and encountered the difference in
my.jar\META-INF\services\org.apache.jena.sys.JenaSubsystemLifecycle
The new version (jena v4.0.0) contains only one line:
org.apache.jena.tdb.sys.InitTDB
The old version (jena v3.17.0) contains two different lines:
org.apache.jena.riot.system.InitRIOT
org.apache.jena.sparql.system.InitARQ
I've added the old two lines to the file and repacked new JAR with it:
org.apache.jena.tdb.sys.InitTDB
org.apache.jena.riot.system.InitRIOT
org.apache.jena.sparql.system.InitARQ
It resolved my issue.
Update: recent Jena v4.4.0 builts with the same "bug".
I'm not an expert and there is probably a better way than patching a JAR by hand.
But I still hope that this solution will help someone like me.
