Maven "doesn't have a 'lib' subdirectory"

Hi, I got this error message using Jenkins v1.596 and it told me to send it here:

Directory tree looked like this:
[root@v20z-002 tools]# tree -di
.
hudson.tasks.Maven_MavenInstallation
Maven32
apache-maven-3.2.5
bin
boot
conf
logging
lib
ext

9 directories

My workaround looked like this:
[root@v20z-002 Maven32]# mv apache-maven-3.2.5/* .

I hope it's helpful.
