Not supporting customized src files locations

[langyizhao]

Our project has its regression tests in test/regression folder with resources in testdata folder.

However with this plugin, by using dirName='regression' it only sets to src/regression/java and src/regression/resources

No way to specify sources and resources outside of src folder. (Or is there a workaround?)

[tkrullmann]

The testSet regression creates a source set that can be modified like any other, for example

testSets { regression }

sourceSets {
  regression {
    resources.srcDir file('/my/custom/dir')
  }
}
