Gradle test tasks with webcontext fails to use entities

Question

I have an issue with some gradle task that should run tests. Since this is some legacy from ant tasks we do not want to include them into our test suite. Especially considering that those ant ones are in testng, and those made by us, and used on regular basis are made using spock and junit.

The problem is that those tests are using some context which works pretty well when I run those tests under eclipse IDE, but it fails if I try to do sth like:

task testNgTesting(type: Test, dependsOn: testClasses){
    useTestNG()
    includes = ["**/*IT*"]
}

But when I try to use that task I get errors like "org.hibernate.MappingException: Unknown entity:" or "java.lang.IllegalArgumentException: No query defined for that name"

Actually the problem is deeper. Gradle is trying to be smart and from whatever folder it has defined it puts classes files into classes folder, and all the other files into resources. When persistence.xml is loaded it scans for annotated entities starting with classpath root for folder it is present in (i.e. build/resources/main). Since all those classes are in build/classes/main it fails to find them. The workaround I've made is introduce two copy tasks. one named is copying persistence.xml into classes folder, and another is moving this file back to resources after the tests are finished. You might want to use something like testNgTesting.finalizedBy(cleanAfterIntegrationTests) to make sure the cleanup occurs even if there are some tests that fails.
