Gradle Plugin / dump plugin with jre dependency

[Matthew Aguirre]

If you need the JDK (not just the jre), you should be able to do the 
following:

>     stage-packages:
>       - fontconfig-config
>       - default-jdk
>       - fonts-dejavu-extra
>       - fonts-ipafont-gothic

In your snapcraft.yaml file instead of just using including the jre.

If this is your complete snapcraft.yaml file, you may also need:

or a subset of these.

There are some limitations with Java that I've found.

Here is my wrapper:

You must set the user.home directory this way for the application to 
work (unless this has been fixed).

As far as updating gradle.  Put in a LaunchPad bug and register an 
Issue.  While I added the gradlew plugin, I am not a gradle user, so I 
can definitely work on adding/fixing work.

If the application tries to use xdg-open or open a web-browser, there 
are more fixes that are needed in my experience.
