[FIXED] How to exclude a single module from Javadoc generation in a Maven multi module project?

Issue

I have a Maven multi module project like this:

foo-parent
    foo-module
    foo-module-new
    foo-other-module1
    foo-other-module2
    pom.xml

And when calling mvn javadoc:aggregate in foo-parent, I want to exclude the module foo-module from Javadoc generation.

Exclusion by package name with the parameter excludePackageNames doesn't work in my case because foo-module and foo-module-new have the same package name.

Solution

Launch the following to generate javadocs only for foo-other-module1 and foo-other-module2 modules (note: always include the aggregator module, in this case foo-parent):

mvn javadoc:aggregate -pl :foo-parent,:foo-other-module1,:foo-other-module2

Since Maven 3.2.1, you can also exclude modules from your reactor, so the above simplifies to

mvn javadoc:aggregate -pl '!foo-module'
