UnitTest fails when running through Gradle [message #1778275]

I have created a standard java project using the gradle plugin that contains some utility classes for my xtext language. I have added this project to my grammars parent project. I have also added some unit test to the utility project that is referencing my languages injector provider and the unit test works within eclipse but when I try to execute the test from my gradle tasks it fails with the following error.

classMethod FAILED
    java.lang.ExceptionInInitializerError
        Caused by: java.lang.NullPointerException

Also the injector for the language we are referencing in the unit test also mixes in another grammar.

besides this did you check the stuff is actually in the jar created by gradle and the gradle dependencies are set right

After further testing we discovered that we had test classes in the utility project that was trying to parse different languages and even though the individual test classes were using the correct injector provider for the language they were trying to parse, the incorrect injector was being used when gradle ran all the tests. We even tried to create a custom injector provider for the tests to use with the following code

       class LibraryStructuredTextInjectorProvider extends LibraryInjectorProvider {
	override protected internalCreateInjector() {
		// trigger injector creation of other language
		new StructuredTextInjectorProvider().injector
		return super.internalCreateInjector()
	}
}

but when using the our custom injector it appears the injector in the return statement in the one that is used. Just like the when mixing in modules the last runtime module that is mixed is the grammar that is getting set. Is there a way around this. Do we need to have separate utility class for each language even though the languages are being mixed in or is they a way to have the correct injector to called.

you should call createInjectoranddoemfregistration or dosetup

I also changed my custom injector to

class LibraryStructuredTextInjectorProvider extends LibraryInjectorProvider {
	override protected internalCreateInjector() {
		// trigger injector creation of other language
		new StructuredTextStandaloneSetup().createInjectorAndDoEMFRegistration
		return new LibraryStandaloneSetup().createInjectorAndDoEMFRegistration
	}
}

Thanks for your help

Can you provide a reproducible hello world example project
Alternatively you could remote debug the gradle test
