RE: debugging maven with eclipse
I still don't have a solution to my problem and really need someone who understands the internals of default-plexus-container to help me through the problem. Please see, below, for a high-level description of the problem. What I've found is that what is happening is that I'm getting this exception (root of the matter): Caused by: java.lang.IllegalArgumentException at sun.reflect.UnsafeObjectFieldAccessorImpl.set(UnsafeObjectFieldAccessorI mpl.java:63) at java.lang.reflect.Field.set(Field.java:656) at org.codehaus.plexus.component.composition.FieldComponentComposer.assignR equirementToField(FieldComponentComposer.java:137) The "Field" in question here is has a class of org.apache.maven.plugin.jar.AbstractJarMojo, a "name" of jarArchiver, and a "type" of org.codehaus.plexus.archiver.jar.JarArchiver. The line of code that is throwing the IllegalArgumentException is: field.set( component, dependency ); The "component", above is a JarMojo (org.apache.maven.plugin.jar.JarMojo) and the "dependency" is a JarArchiver (org.codehaus.plexus.archiver.jar.JarArchiver). Nothing seems out-of-whack to me. As stated, below, everything works fine when I'm simply building the subdirectory - only when I try to do a reactor build of the parent (which includes this module as a child) do I get this problem. Can anyone point me in a direction that might lead to figuring out what is going wrong? I can't debug into Field.set (part of the reflection api) and I see no reason why java.lang.reflect would be failing - especially since we execute the exact same code in other cases without any problem. Help! Thanks. -- Eric From: Swenson, Eric Sent: Thursday, October 12, 2006 9:18 PM To: 'Maven Developers List' Subject: debugging maven with eclipse Can anyone point me to instructions on how to use eclipse to debug maven? I'm having a problem that no one, so far, has commented on - namely that when I do a reactor build of my project (top-level with sub-projects), I get the error (when doing "mvn install"): [ERROR] BUILD ERROR [INFO] [INFO] Internal error in the plugin manager executing goal 'org.apache.maven.plugins:maven-jar-plugin:2.1:jar': Unable to find the mojo 'org.apache.maven.plugins:maven-jar-plugin:2.1:jar' in the plugin 'org.apache.maven.plugins:maven-jar-plugin' But when I go to each subdirectory in the project and do a "mvn install", they all complete successfully. Only when I try to run from the parent directory do I have this problem. Running with the -X -e options doesn't give me anything useful. Is there an easy way to produce an eclipse project from the maven2 source tree? Or do I have to manually all all the "src" directories in a new project? I'd like to run under the debugger and step through the execution to pinpoint the issue. Thanks. -- Eric
RE: debugging maven with eclipse
Hi Franz, I'll take a look at your writeup (thanks). However, I am happily debugging right now in the DefaultPlexusContainer code that appears to be the source of my problem. I'll report on my findings if/when I figure it out. Thanks again, though. I will look over your writeup to make sure I didn't miss anything. -- Eric -Original Message- From: Franz Allan Valencia See [mailto:[EMAIL PROTECTED] Sent: Thursday, October 12, 2006 11:40 PM To: Maven Developers List Subject: Re: debugging maven with eclipse Good day to you, Eric, I havve just created (or rather, continued) this short tutorial on debugging maven with eclipse, [1] However, I am a windows user, so my answer is based on windows.

RE: debugging maven with eclipse
I apologize for the stupidity, I used the command line parameters rather than the vm parameters. I can get past this problem and into MavenCli now. So I'm going to try to debug the problem with the plugin manager.

Would you mind sharing the issue link with us?
