Subject NullPointerException when using release:prepare
Date Tue, 05 Sep 2006 17:29:24 GMT
Hello,

  I'm seeing a NullPointerException when trying to execute mvn
release:prepare.

  I have seen the subject discussed previously on the
list<http://mail-archives.apache.org/mod_mbox/maven-users/200511.mbox/%253C438C5BA1.7000504@venisse.net%253E>.
The solution provided then was to use the -U flag for updating the release
plug-in, but that did not work in my case. I am seeing this with both maven
2.0.2 and 2.0.4 under Windows XP and Sun's Java 1.5.0_06-b05.

  What can I try?

This is the output I get. I get the same result without -DdryRun=true.
