[jira] [Created] (MJAVADOC-570) --add-modules expects comma-separated arguments

["Gili (JIRA)" <ji...@apache.org>]

Gili created MJAVADOC-570:
-----------------------------

             Summary: --add-modules expects comma-separated arguments
                 Key: MJAVADOC-570
                 URL: https://issues.apache.org/jira/browse/MJAVADOC-570
             Project: Maven Javadoc Plugin
          Issue Type: Bug
          Components: javadoc
    Affects Versions: 3.1.0
            Reporter: Gili


It's quicker for me to explain this problem that produce a minimal testcase for it. In AbstractJavadocMojo line 5079 we invoke:
{code:java}
addArgIfNotEmpty( arguments, "--add-modules", JavadocUtil.quotedPathArgument(addModulesLine ) );{code}
This gets converted to {{addArgIfNotEmpty()}} with {{splitValue=true}} which means that comma-separated values get converted to newline-separated values. 

{{--add-modules}} does not like this and does not consume the subsequent arguments (they probably get treated as source files instead).

We should be invoking {{addArgIfNotEmpty()}} with {{splitValue=false}} instead.

If I provide a PR for this, do you still need a testcase?
