Hello, if this is a redundant question please refer me to a thread that has covered it. I searched through the last 3 months of the mail archive w/ no luck.
I checked out the maven-assembly-plugin in order to add a piece of functionality. It built fine, and installed into my local .m2 repo. But trying to use it in my current project's build yielded a lovely IncompatibleClassChangeError. I'm assuming someone has run into this before, but not sure what info I should include in my post to have the community help me debug the issue. Thanks for the help, Tom Hartwell Stack Trace: [INFO] [assembly:assembly] [INFO] ------------------------------------------------------------------------ [ERROR] FATAL ERROR [INFO] ------------------------------------------------------------------------ [INFO] null [INFO] ------------------------------------------------------------------------ [INFO] Trace java.lang.IncompatibleClassChangeError at org.apache.maven.plugin.assembly.io.DefaultAssemblyReader.readAssemblies (DefaultAssemblyReader.java:74) at org.apache.maven.plugin.assembly.mojos.AbstractAssemblyMojo.execute(Abst ractAssemblyMojo.java:253) at org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginMa nager.java:412) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(Default LifecycleExecutor.java:534) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeStandaloneGoa l(DefaultLifecycleExecutor.java:488) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal(DefaultL ifecycleExecutor.java:458) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandle Failures(DefaultLifecycleExecutor.java:306) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments( DefaultLifecycleExecutor.java:219) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifec ycleExecutor.java:140) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:322) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:115) at org.apache.maven.cli.MavenCli.main(MavenCli.java:256) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.jav a:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessor Impl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java:315) at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) at org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:430)
