Hello, all.
I have been working on this problem myself (digging through archives,
google, etc).
I have a patch (which at least makes the build work for me). I'm certain
there must be a better way, so would someone mind taking a look at this
patch, please?
I'd appreciate any feedback. Thanks.
Regards,
Troy

Subject: [mojo-user] Problems with J2ME plugin
Hello, all.
I am new to Maven, and I am having some problems with the J2ME plugin
(sandbox). Please let me know (privately) if this is the wrong forum for my
question, which follows.
* * *
Here's what I see on my console:
============================
jabs [~/tools/mats/trunk] $ mvn -Dplugin=j2me install
[INFO] Scanning for projects...
[INFO] ---------------------------------------------------------------------
[INFO] Building mats
[INFO] task-segment: [install]
[INFO] ---------------------------------------------------------------------
[INFO] [resources:resources]
[INFO] Using default encoding to copy filtered resources.
[INFO] [compiler:compile]
[INFO] Nothing to compile - all classes are up to date
[INFO] [j2me:preverify {execution: default}]
[ERROR] error output :
Error preverifying class com.asurion.mats.App
java/lang/NoClassDefFoundError: java/lang/Object
============================
>From what I can tell, the CLASSPATH for the preverifier is not set properly.
Can someone advise me on how to fix this problem, or direct me to the proper
documentation?
Thank you!
Troy
