Paul Sundling commented on MPMD-67:
-----------------------------------
I don't think the typo is the issue. I think you have to specify targetJdk to
be 1.5 even if you're using JDK 1.6
This failed with lots of errors "Can't use generics unless running in JDK 1.5
mode":
<plugin>
<!-- http://maven.apache.org/plugins/maven-pmd-plugin/ -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<configuration>
<!-- snip logs of config -->
<targetJdk>1.6</targetJdk>
</configuration>
</plugin>
even though I'm using JDK 1.6 for compiler plugin settings and an actual JDK
1.6. But if I change that to
<targetJdk>1.5</targetJdk>
Then it quits failing. I think it should work even if we have a later setting
than 1.5! This bug should be reopened or another one created. This is using
version PMD 2.4
Now for the strange part. This behavior happens when doing 'mvn site:site
site:deploy', but NOT when running 'mvn pmd:pmd' directly.
