Groovy++ on Eclipse and Jboss Seam

[Will Piasecki]

Hello there!

I've been watching this group for sometime but only joined now, so, hi!

Well, i'd like to ask for a little help... I've been coding in groovy for some months and keeping an eye on groovy++ (it gives the best of both worlds!) and recently tried to insert it into a web project of mine which uses Jboss Seam, but it didn't worked. I've been searching for some similar problem for some days but didn't manage to .find { a solution } (forgive the pun).

Right now my classpath only have one jar for groovy: groovy-all-1.7.10.jar. When i insert groovypp-1.7.10.jar i can compile successfully, but upon trying to start tomcat (from eclipse) i get the following stacktrace (mostly from seam):

When i add the groovypp-all-1.7.10.jar, eclipse gets me the following error:

"Errors occurred during the build.
Errors running builder 'Java Builder' on project 'rew-image'.
java.lang.AbstractMethodError"

The error happens by just having the jar on classpath.

The "Page" class is compiled from another project of mine, it is a jar on the project.

Also, using groovypp-all-1.7.10.jar on classpath it compiles successfully using ant.

OS: Ubuntu 9.10

Java: java version "1.6.0_22"
   Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
   Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)

Groovy: 1.7.10

Eclipse: Eclipse SDK
Version: 3.7.0
Build id: I20110428-0848

Any help is greatly appreciated.

Thanks and congratulations for the work on G++, i've read half the wiki, already.

There haven't been any new releases for some time now, I suspect Alex has lost interest.Groovy has indicated on its plans to potentially support static compilation in the 2.x version so I suspect (without knowing) that Alex has decided not to continue.
