local repository woes

[wessie <jo...@gmail.com>]

Hi all,

I've been struggling with abit of a strange problem for the last few days.

The situation is this: I have a box with 2 maven installations - versions
2.0.4 and 2.0.9. I also have 2 local repositories - the original repository
located at /app/maven/.m2/ and a new repository located at /app/maven/.m2b/

Both repositories are very similar (the new repository has a few more
artifacts) and both repositories have the help-plugin installed. I changed
the 2.0.9 maven version's conf/settings.xml file to point to my new
repository with the line
<localRepository>~/.m2b/repository</localRepository>

However, when I run the following command (with maven 2.0.9)
mvn -e -X help:effective-settings it says that it can't find the
help-plugin. See output below:

mvn -e -X help:effective-settings
Using /app/maven/java/java6/jdk1.6.0_01
+ Error stacktraces are turned on.

I've tried switching local repositories on my WinXP machine and it worked
successfully. 

Does anyone have any ideas?

Regards
Wessie!
