Test source folder must have an output folder that is not also used for main sources #1635

Hi,

I'm hitting the following error when a project that has integration tests wants to use resources from main (see below):

Test source folder 'src/integration-test/java' in project 'integration-tests-issue' must have an output folder that is not also used for main sources

This works fine when calling ./gradlew integrationTest.

I'm attaching a sample project to reproduce this:

integration-tests-issue.zip

I've tracked down the issue to including "$projectDir/src/main/resources" in resources.srcDirs when defining integration tests:

resources.srcDirs = ["$projectDir/src/main/resources", "$projectDir/src/integration-test/resources"]

from

sourceSets {
    integrationTest {
        java.srcDir "$projectDir/src/integration-test/java"
    resources.srcDirs = ["$projectDir/src/main/resources", "$projectDir/src/integration-test/resources"]
        compileClasspath += main.output + test.output
        runtimeClasspath += main.output + test.output
    }
}

The fix is to simply use:

resources.srcDirs = ["$projectDir/src/integration-test/resources"]

I'm using Emacs with lsp-mode/lsp-java, but I don't think this would be related to lsp-mode/lsp-java. It might be the error is not in Eclipse JDT LS either but from the stack trace it seem it's down the line. This is the full stack trace:

Same issue here with: resources.srcDirs = ['src/contractTest/resources', 'src/contractTest/contracts', 'src/main/resources']

After removing 'src/main/resources' it works fine.

It doesn't produce any errors In IntelliJ. Would be nice if eclipse is also more robust in this case.

A similar problem with custom source pathes and testFixtures: https://github.com/eclipse/buildship/issues/1115

Are there currently any workarounds for this, aside from simply removing the srcDir? Unfortunately in my situation it isn't viable.
