How to resolve “javadoc: warning - Multiple sources of package comments found for package a.b.c”?

问题

I am very much outdated, but I have just upgraded my project to use JDK 1.5 from JDK 1.4, and now when running mvn javadoc:javadoc, I encounter the following javadoc warnings:

[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.a"
[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.b"
[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.c"
[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.a"

What do I need to do to fix them? Has anything changed from JDK 1.4 to 1.5?

Thanks!

This thread in the Oracle forums discusses this.

Maybe you need a new version of maven?
