NPE when generating site:site
-----------------------------
Key: MVERSIONS-89
URL: http://jira.codehaus.org/browse/MVERSIONS-89
Project: Maven 2.x Versions Plugin
Issue Type: Bug
Affects Versions: 1.1
Reporter: Alexandre Navarro
I have one project of my project where version report generates a NPE.
In this pom, I used scope import.
Like
<dependencyManagement>
<dependencies>
<dependency>
<groupId>ged.archi</groupId>
<artifactId>root-tech-env</artifactId>
<version>1.0.3</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
and some range version dependency
<dependency>
<groupId>sgcib.ged.archi.common</groupId>
<artifactId>common-srv</artifactId>
<version>[2.2.0, 2.3)</version>
<scope>compile</scope>
</dependency>
I think the problem comes from range version dependency.
This is the error.
