Java buildpack fails for unsatisfied dependency

[adicocco]

Hello,

I'm trying to use latest java-buildpack version with
cf push -p ~/helloworldJava/HelloWorld.war -b https://github.com/cloudfoundry/java-buildpack.git
It is a simple java application that worked since few hours ago (I noticed that new version of buildpack has been released), but now it is failing with the following error:
-----> Downloaded app package (4.0K)
Cloning into '/tmp/buildpacks/java-buildpack'...

Staging failed: Buildpack compilation step failed

FAILED
Server error, status code: 400, error code: 170004, message: App staging failed in the buildpack compile phase

It seems that latest version has an unsatisfied dependencies from zip gem.

Can you help me on this?

Thank you.

Regards.
Antonio

@adicocco Great catch. I've reverted the recent change and we'll have another go at it. Sorry for the inconvenience.
