Hi,
I've run into a problem with maven on OS X and JDK 1.5. We're just
starting to migrate our project over to Maven 2 and the initial
project will not build on my Mac. I can reproduce the problem by
creating a 'Hello World' project using this command:
$ mvn archetype:create -DgroupId=foo.bar -DartifactId=foo-bar
and after a chunk of output, it printed 'BUILD SUCCESSFUL'. However,
when compiling the project, it fails with the following error (full
stack trace at end of mail).
[ERROR] BUILD ERROR
[INFO]
------------------------------------------------------------------------
----
[INFO] Fatal error compiling
Embedded error: Prohibited package name: java.lang
If I switch to a 1.4 JDK, the project builds without problems.
Unfortunately our actual project requires JDK 1.5.
Can anyone give advice on what, if anything, I can do to workaround
this?
thanks
Conrad
