[johnrengelman]

Thanks. I'll get a patch in for this soon.

[Bakrog]

Is there a workaround?

[johnrengelman]

Haven't looked into it yet. The workaround is probably to run Gradle 2.4.

[Nelyus]

my work around is to use Gradle 2.4 (through gradlew)

[thiagogcm]

@johnrengelman I haven't tested it yet but I think you can fix it by changing the imports org.gradle.mvn3.org.codehaus.plexus.util.IOUtil to org.apache.commons.io.IOUtils

[Nelyus]

thanks
