Maven 2 requires write access to a read only default repository
---------------------------------------------------------------

                 Key: MNG-4575
                 URL: http://jira.codehaus.org/browse/MNG-4575
             Project: Maven 2 & 3
          Issue Type: Bug
          Components: Embedding
            Reporter: Costin Caraivan


We have lots of Maven 2 jobs run by a Hudson CI server, each with a separate repository ("Use private repository" aka maven.repo.local). We decided to see if the separation between builds works as expected - each project gets 1 repository and no other project interferes with it. However, after making the default Maven 2 local repository read only (chmod u-w $HOME/.m2/repository), the builds start crashing. 

I posted this issue first in the Hudson issue tracker and according to the comments in that issue, it appears that Maven 2 needs write access to the default repository, although it is configured to not use it.

In my opinion - this is a bug - why does Maven 2 need to write to:
a) a repository where it shouldn't use anyway
b) a repository where at most it should read (maybe to set some properties or similar)

Here is the relevant issue from the Hudson tracker:
http://issues.hudson-ci.org/browse/HUDSON-5751

Since Maven 2.2.1 works with this setting, I presume that it has been fixed, and that it's a bug in the embedded 2.0.4 used by Hudson. Is there any way to have a new release of the Maven embedder for Maven 2?

Regards.
