I'm playing with the infamous all-subprojects javadocs again, as my original
changes for 0.9 ceased to function with preview release 3.
Arguably, I was not doing things the correct way in the first place, but it was
interesting to discover why it no longer works.
alljavadoc.doFirst()
{
Javadoc task ->
task.project.subprojects.each {
Project subproject ->
task.source = task.source + subproject.javadoc.source
task.classpath = task.classpath + subproject.javadoc.classpath
}
}
Now I get "Cause: Cannot invoke method plus() on null object"
Not sure if this is a DSL or groovy version change, or what.
Anyway, in attempting to find a uniform way of adding to the values, it seems
that source and classpath are both set to null objects (at least as visible via
the implicit get() methods).
Is there a reason that list-type objects are initialized to null (or in the
case of source within SourceTask made to appear to be null) instead of treated
as empty collections? I suspect it might be for performance reasons, or maybe
just a style reason, but it seems inconsistent with many other collections that
are initialized to empty instead of null.
