Hi,

While testing a build of mockito against a new json-simple releae I've
experienced a FTBFS due - IIUC - to gradle failing to honor correctly
a maven relocation:

...
Generating gradleApi JAR file: /<<PKGBUILDDIR>>/.gradle/caches/3.2.1/generated-gradle-jars/gradle-api-3.2.1.jar
Generating JAR file 'gradle-api-3.2.1.jar'

Parallel execution is an incubating feature.

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':runtime'.
> Could not find json-simple.jar (com.googlecode.json-simple:json-simple:debian).
  Searched in the following locations:
      file:/usr/share/maven-repo/com/googlecode/json-simple/json-simple/debian/json-simple-debian.jar

* Try:
Run with --debug option to get more log output.

* Exception is:

        at org.gradle.api.internal.artifacts.ivyservice.ErrorHandlingConfigurationResolver$ErrorHandlingResolvedConfiguration.getFiles(ErrorHandlingConfigurationResolver.java:208) 
...


As I understand it, gradle should follow the relocation and look for
 file:/usr/share/maven-repo/com/github/cliftonlabs/json-simple/debian/json-simple-debian.jar
instead of
 file:/usr/share/maven-repo/com/googlecode/json-simple/json-simple/debian/json-simple-debian.jar

This bug is easily reproducible building mockito againt json-simple 2.3.0-1~exp1 currently in experimental.

Thanks,
