Add an example Maven file

[ccleve]

For us non-Gradle users, it would be helpful to have an example of how to use this in Maven.

This might take some time, but I'm more than happy to accept contributions. I want this to become a community-run project.

This is a start, but doesn't work. I am placing all the jar deps in a lib/ folder. Does capsule expects all the jars to be unpacked in the main jar?

Thank you!
By default, Capsule adds only those jars at the root of the capsule to the classpath. Either put them there, or add lib to the App-Class-Path manifest attribute.

[rodlogic]

I tried removing the lib folder and this is what I get:

CAPSULE: Launching app app.AppService
CAPSULE: /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/jre/bin/java  -Dcapsule.log=verbose -Dcapsule.jar=/work/trunk-all/app/target -classpath /work/trunk-all/app/target/app-5.4-SNAPSHOT-capsule.jar app.AppService
Error: Could not find or load main class

Try upgrading to capsule 0.4.0. This seems like a bug that has been fixed.

Also, why is Extract-Capsule set to false? Aren't the dependencies embedded? If you're using embedded dependencies, don't set Extract-Capsule (or set it to true, which is the default).

[pron]

Added a working demo (full capsule -- i.e. embedded dependencies -- only): https://github.com/puniverse/capsule-demo

• Assembly
• POM

That example now has an assembly for a capsule with external dependencies, too.
