      Description

      When invoking the site plugin (with javadoc reporting enabled) for a project that depends on both the main artifact and the tests artifact of another project, the classpath passed to the javadoc command is incorrect.

      For example:
      Project A produces the following artifacts:

      • ProjectA-version.jar (main artifact)
      • ProjectA-version-tests.jar (test classes)

      And project B has dependencies similar to this:

      <dependency>
        <groupId>...</groupId>
        <artifactId>Project1</artifactId>
        <version>...</version>
      </dependency>
      <dependency>
        <groupId>...</groupId>
        <artifactId>Project1</artifactId>
        <version>...</version>
        <classifier>tests</classifier>
        <scope>test</scope>
      </dependency>

      Then only one of the jars is included in the classpath passed to the javadoc command. (Normally it seems to be the main artifact, although on one of my projects it was the tests artifact instead.) This causes lots of warnings, or for some projects causes the build to fail.

      Note that if I explicitly run the javadoc goals (i.e. "mvn javadoc:javadoc" or "mvn javadoc:test-javadoc") then the classpath is populated correctly and no errors are shown. It's only when the site plugin/phase launches it that the classpath is wrong. I've also found that the order of the dependencies within the POM file seems to make a difference in some cases.

      I've attached a zip file containing two projects to reproduce this. To run it:

      1. run mvn install on project1
      2. run mvn site on project2 (to see the warnings) or mvn javadoc:test-javadoc

      The warning looks like this:

      [WARNING] Javadoc Warnings
      [WARNING] D:\code\EclipseWorkspaces_chris\PaymentCard\project3\src\main\java\repro3\MyClass3.java:3: cannot find symbol
      [WARNING] symbol  : class MyClass1
      [WARNING] location: package repro1
      [WARNING] import repro1.MyClass1;
      [WARNING] ^
