Splitting all output directories in Gradle

Question

Gradle 4.0 came out yesterday and I updated my project for it.

Now I am getting the following warning:

Gradle now uses separate output directories

Answer 1

My case was a bit specific because output classes directories were used to construct classpath entry for command-line execution. But perhaps this will help someone.

I decided to concatenate all output directories. The change I made was form

sourceSets.integrationTest.output.classesDir

to

ext {
    classpathSeparator = System.properties['os.name'].toLowerCase().contains('windows')?";":":"
}
...
sourceSets.integrationTest.output.classesDirs.join(classpathSeparator)
