Gradle 4 - replacing deprecated Test::testClassesDir

[ddimitrov (Dimitar Dimitrov)]

When replacing this deprecated method, which shall we prefer:

  testClassesDirs = files(sourceSets.integrationTest.output.classesDir)

or

  testClassesDirs = sourceSets.integrationTest.output

Strictly speaking, the latter will also bring the resources into the classpath. Is that a good thing?

Neither

testClassesDirs = sourceSets.integrationTest.output.classesDirs

If you used multiple languages for the same source set, they could use separate output directories.

Would be nice going forward to have the typical replacements mentioned in the deprecated methods javadoc.

I had a similar problem when bumping from an old Gradle 2.10 to current 5.2.1 :

task integrationTest(type:Test) {
    testClassesDir = project.sourceSets.integrationTest.output.classesDir

Could not get unknown property ‘classesDir’ for integration test classes of type org.gradle.api.internal.tasks.DefaultSourceSetOutput.

And this fixed it:

testClassesDirs = project.sourceSets.integrationTest.output.classesDirs
