Question

I am trying to execute a test inside a gradle project.But when Itry to execute the tests using 'gradle test' in Intellij it fails .

what I have tried

1. create and build the project without error using 'gradle clean build'

2. open run configuration in intellij , select gradle , and create and execution with gradle task 'test'

3. execute newly created gradle run configuration

what I observe

1. gradle fails at task 'test' with error 'Error: Could not create the Java Virtual Machine.'

2. also gradle run never stops until I forcefully stop it

3. also it keep printing ' gradle executor 1(,2,3 and so on) executing , failed '

I am using java 9 , intellij , gradle .

Getting similar issue, but to be specific:

Task :run FAILED

Error: Could not create the Java Virtual Machine.

To solve my issue, I basically had to select correct JDK for my IntelliJ.

To switch the Java runtime used to run IntelliJ IDEA:

On the Help menu, click Find Action, or press ⇧⌘A.

Find and select the Switch Boot JDK action.

Select the desired JDK and click OK.

Found this resource that helps! https://www.jetbrains.com/help/idea/tuning-the-ide.html

If by any chance you select a wrong JDK version, and the IDE not starting anymore, delete idea.jdk file: https://intellij-support.jetbrains.com/hc/en-us/articles/206544879-Selecting-the-JDK-version-the-IDE-will-run-under?page=3
