Hello,
I am trying to develop a maven plugin. When I explicitly invoke the plug-in,
I get a linkage error which I have had a very hard time resolving. Any help
would be greatly appreciated.
I am using the m2 Eclipse plugin to build my maven projects. I have tried
deleting the local repository and re-downloading all dependencies with the
same results. When I run mvn from the command line, I get a
slightly different printout which hints at a problem related to logging.
Here is the printout I get when I run my plug-in goal from Eclipse:
[ERROR]
com.cisco.ipcentral.maven_ipcentral_plugin.IPCentralMojo#execute()
caused a linkage error (java.lang.NoClassDefFoundError). Check the
realms:
