[m2e-users] m2eclipse 1.0 : NullPointerException when lifecycle-mapping

[Adrian Gonzalez <adr_gonzalez@xxxxxxxx>]

Hello,

I have the attached pom.xml.

When you don't specify version information, you get a dialog box with the following error :

Errors occurred during the build.

Errors running builder 'Maven Project Builder' on project 'pag'.

java.lang.NullPointerException

When you specify <version>1.0.0</version> everything works fine.

This forbids me to put version information in a parent pom.

Shoud i raise an issue ?
