JRubyExec should employ bundler-esque version pinning behaviors #154

Open rtyler opened 9 years ago

rtyler commented 9 years ago

As a user, when I'm evaluating newer or older versions of a Gem, the runtime environment of JRubyExec may lead to inadvertently loading incorrect versions of a gem unless I explicitly ./gradlew clean between invocations of the JRubyExec task.

A concrete example, if I'm seeing issues with v2 of a gem, so I downgrade in my build.gradle to v1, the v2 is still in build/gems and will still be used by default, whether I'm aware of it or not.

This is confusing behavior and should be fixed IMO

One option that would address this that @mkristian and I discussed was making it such that the GemUtils. code would prune the gem specifications for versions that are not actively being used from the$buildDir/gems` directory.
