Hey, Is there are particular reason we explicitly configure Zip64Mode.Never for the ZipOutputStream? ( https://github.com/gradle/gradle/blob/master/subprojects/core/src/main/groovy/org/gradle/api/internal/file/copy/AbstractZipCompressor.java#L31 )
This means that we don't support creating huge zips/jars (>~4G or >~65k entries) correctly (e.g. the creation of the archive succeeds but it does not seem to be openable). There's a forum ticket that we transferred to jira: http://issues.gradle.org/browse/GRADLE-2964 I've also stumbled upon it at the client's.
