Directories of Maven templates are read-only and can only be set with the Browse button.
However, I recently reinstalled Windows 7, and my disk partitions changed. They are not identified by the same letters than before.
Therefore, my former Eclipse preferences are not all correct.
And when I complete a SU wizard with custom POM files, it results in a NPE.
SU and SA wizards should check on the first page (choice page and SA page) that the Maven preferences are correct.
When incorrect, the error message should provide a link to open the preferences.
Besides, the preference page should display an error when the Maven preferences are incorrect.
