gradle run TestNG test cause "Error occurred during initialization of VM"

Question

I have one test framework project which was created via Gradle/Idea, and since this project is one test framework project and all the test cases were located under the src/main/java folder.

sourceSets{
test{
java.srcDirs = ['src/main/java']
}
}

By Using gradle, I want to create one new task in build.gradle to run the specified testNG xml file via command line.

task runTest(type: Test){
useTestNG(){}
}

but always I got error like the below.

Error occurred during initialization of VM
java/lang/NoClassDefFoundError : java/lang/Object

Could anyone support this? Thanks a lot.

I understand that your tests are in main it is not ideal but well yes you can amend the default sourcesets.

sourceSets.test.java.srcDir 'src/main/java'

if you run it from IntelliJ you can add

idea.module {
    testSourceDirs += file('src/main/java')
}

As intelliJ is not very good with stuff like gradle source sets.

About your error

Error occurred during initialization of VM
java/lang/NoClassDefFoundError : java/lang/Object

Is your PATH / JAVA_HOME set? It seems like it might not be.
