Nullpointer in Dependencies report (with latest plugin versions)
When I do a
mvn -U -X site
I get the error below.
I remember a similar error with the previous version of the
project-info-reports plugin, but that was fixed when I upgraded to the
latest version a few weeks ago. Now it seems a new kind has appeared.
To bad the trace doesn't mention which dependency is actually causing
the problem.

Yes Geoffrey, system scoped dependencies are always "suspect" when you
run into bugs. Which is why I personally advocate against using them
where ever possible. ;-)

Re: Nullpointer in Dependencies report (with latest plugin versions)
Posted by Geoffrey De Smet <ge...@gmail.com>.
After a bit of tinkering and debugging, I suspect this dependency caused it:
<!-- JNLP -->
<dependency>
<groupId>javax.jnlp</groupId>
<artifactId>jnlp</artifactId>
<version>1.5.0</version>
<scope>system</scope>
<systemPath>${java.home}/lib/javaws.jar</systemPath>
<!--This isn't purely jnlp, it contains sun files... -->
</dependency>
Although it's quite clear it uses the latest version of the project-info
report plugin:
org.apache.maven.plugins:maven-project-info-reports-plugin:2.0
I just found on jira that the bug in question was reopened after the 2.0
release and should now be fixed for 2.1.
