Project: Maven 2.x Javadoc Plugin
Issue Type: Bug
Affects Versions: 2.2
Reporter: Greg Luck
I have two projects which use the javadoc plugin. Ehcache and JPam.
Both started giving this error in the last few days:
[INFO] Velocity successfully started.
[INFO] [javadoc:javadoc]
[WARNING] No docletpath option was found. Please review <docletpath/> or
<docletArtifact/> or <doclets/>.

Reverting to 2.0 by adding a version identifier of 2 fixes the problem:
<!-- javadoc -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.0</version>
</plugin>
If 2.0 works and 2.2 does not, is this a bug in 2.2 javadoc, or is it a bug in
the parent project: org.apache.maven.plugins. The version in 2.2 is 4, in 2.0
it was 3.
<parent>
<artifactId>maven-plugins</artifactId>
<groupId>org.apache.maven.plugins</groupId>
<version>4</version>
</parent>
I am working around by staying on 2.0.
