如何在javadoc：fix中修复“ MavenInvocationException”

Question

I'm getting this Exception if I try to execute the goal javadoc:fix.

Execution default-cli of goal org.codehaus.mojo:clirr-maven-plugin:2.2.2:check failed: Invalid byte tag in constant pool: 15

If I remove all sourcecode from the src/main/java location it works perfectly fine. If I add a new class to the empty directory it works fine. But when I revert the deletion the error comes back.

So I think my sourcecode is "broken" where have I to search to find the "broken" file ?

Here is the pom.xml:

If I clear my local repo I get only a Warning "[WARNING] No previous artifact has been deployed, Clirr is ignored."

But as soon I change the Version higher and there a two versions of my artifact in my repo I still get the error.

I think I have found the important part in the javadoc-maven-plugin https://github.com/apache/maven-javadoc-plugin/blob/master/src/main/java/org/apache/maven/plugins/javadoc/AbstractFixJavadocMojo.java

Line: 193-205 - Why it is hardcoded ? Line: 450 The Try / catch to execute the Clirr

Answer 1

According to the stacktrace the actual library causing problems is bcel. It might work if you add a new version as plugin dependency to your maven config.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <!-- .... other stuff -->
    <dependencies>
      <dependency>
         <groupId>org.apache.bcel</groupId>
         <artifactId>bcel</artifactId>
         <version>6.3.1</version>
      </dependency>
    </dependencies>
</plugin>

If that doesn't work, i would go for this workaround. Find the classes that causes the problem and exclude them.

To find the classes that cause problems:

1. Add an exception breakpoint to org.apache.bcel.classfile.ClassFormatException
2. Start the maven generation in debug mode
3. Wait till the breakpoint is reached
4. Look at the org.apache.bcel.classfile.ClassParser.parse activation frame, i would expect to see the classname in one of the variables or fields. (Maybe you need to look around further down the stack).
5. Exclude the class (maybe the whole package)
6. Repeat at 2
