I see the exact same issue as Could not calculate the signature for Jar file icu4j when running with Gradle 3.5 GA on a multi project build.
Build time: 2017-04-10 13:37:25 UTC
Ant: Apache Ant™ version 1.9.6 compiled on June 29 2015
JVM: 1.8.0_121 (Oracle Corporation 25.121-b13)
OS: Linux 4.4.0-62-generic amd64
Is there a way to fix this without nay major udpates to the build.gradle files?
