Support for rocket / rkt

[benmccann]

It could be cool to add support to sbt for building rkt containers. I think we could basically just copy what @justinsb did in justinsb/docker-maven-plugin@aaa5db4

Sounds great. You have time for a pr?

[justinsb]

I will have a look to see if I can add support :-)

[muuki88]

Awesome, thanks :) If you need any help don't hesitate to ask.

I've had a look; I'm trying to reuse the appc-java package here (the idea being that we create one library for the JVM). However, it looks like scala has a problem loading this library, because I hit this error:

[error] error while loading ContainerBuilder, class file '/Users/justinsb/rocket/sbt-native-packager/lib/appc-0.1.0-SNAPSHOT.jar(com/coreos/appc/ContainerBuilder.class)' is broken
[error] (class java.lang.NullPointerException/null)

It looks like this is because some of the annotations aren't found (?) - at least that is what Stack Overflow suggested. I'm guessing this is because appc-java uses the AWS SDK now, which uses gson.

I'm happy to make whatever changes to appc-java that are helpful, but I'm not a Scala expert so it looks like I'm stuck here!

Do you have a link to the current state of you work (like commit sha of your fork)? Then it would be easier to take a look. And the stackoverflow questions you mentioned would be nice to take a look at. From what I see

• lib/appc-0.1.0-SNAPSHOT.jar is this not on maven-central?
• gson works with scala case classes (as far as I have used it)

@justinsb I wonder if it could also be the version of Scala that's being used. I see a bug that looks related that was fixed in Scala 2.10.4 and it appears sbt-native-packager is using 2.10.2. I sent a PR to upgrade, so perhaps worth a shot to see if that helps.

[muuki88]

@justinsb I'll release a 1.0.1 this WE then you can give it another try :)

[muuki88]

released.

[benmccann]

@justinsb could you give your code another shot now that we've updated the Scala version? or share it so that we can try it?

[yaneeves]

Any update?
