DefaultSourceDirectorySet needs an overload for srcDir(List<Object> srcDir)

DefaultSourceDirectorySet.java

//SourceDirectorySet set 
//List<Object> someList
set.srcDirs( someList ) //fails
set.srcDirs( someList.toArray() ) //workaround

The failing call invokes srcDirs(Object) and the subsequent failure is in doGetSrcDirTrees(), in the else branch where fileResolver.resolve(path) throws an error.

Cannot convert the provided notation to a File or URI: [the provided list].
  The following types/formats are supported:
    - A String or CharSequence path, for example 'src/main/java' or '/usr/include'.
    - A String or CharSequence URI, for example 'file:/usr/include'.
    - A File instance.
    - A URI or URL instance.

The workaround invokes the srcDirs(Object…) overload.
