How can I disable checkstyle rules for tests in gradle?

Question

with maven I disabled checkstyle for tests, how can I disable the checkstyleTest task in gradle?

I've tried variations o these separately

checkstyle {
  toolVersion = '6.10.1'
  exclude '**/*Test.java'
}
checkstyleTest {
   sourceSets = []
}

it all ends up in errors

Answer 1

Apparently you can set the undocumented (maybe underdocumented? maybe it's inherited or something ) enabled property on checkstyleTest (and to access that in the closure is in no way obvious by the documentation) to false.

checkstyle {
  toolVersion = '6.10.1'
  checkstyleTest.enabled = false
}

Answer 2

The cleanest way is to tell Gradle to execute only the Checkstyle tasks that you need, by specifying them like so:

checkstyle {
    toolVersion = '6.10.1'
    sourceSets = [project.sourceSets.main]
}

Just disabling the unneeded tasks would also work, but I think the above is cleaner.

In the above example, the checkstyleTest task will remain in the task list, even though it is not executed. I prefer a clean task list, so you can remove the unused task via

project.tasks.remove(project.tasks['checkstyleTest']);
