I am getting an exception running the maven2 checkstyle plugin.
Since I need a custom checkstyle configuration, I'm running the Checkstyle
plugin version from SVN. I updated around noon today, built and installed
the snapshot.
Previously, running the release plugin and "sun" checks, the plugin ran
without error and I got some results from checkstyle.
I have read the Jira issue about checkstyle config files and read recent
comments in the archive for this mailing list that contain the word
"checkstyle" I have generated and read the new site docs for for the
checkstyle plugin that I just got from SVN.
Here is a bit of the POM:
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-project-info-reports-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>surefire-report-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
<version>2.0-beta-2-SNAPSHOT</version>
<configuration>
<!--
configLocation>config/maven_checks.xml</configLocation-->
<configLocation>../AA-IFS-checkstyle-rules.xml
</configLocation>
</configuration>
</plugin>
</plugins>
</reporting>
NOTE: I get the same error whether I use my xml file (as shown) or
config/maven_checks.xml (which is currently commented out). If I change the
config file name to some non-existent filename, I get a different error
saying that it can't find the config file. My config file was generated by
the eclipse 3.1 checkstyle 4.? plugin.
This bit of POM is in the parent. The error occurs in the 1st child project
that is processed. The parent doesn't have any source and does nothing but
serve as a base POM.
Here is the error: (with -e)
