Nick Williams commented on MJAVADOC-449:
----------------------------------------
I'm seeing something slightly different, and I'm hoping someone here can help
me understand if this is a different manifestation of this bug (and, if so, if
this fix will still work) or if I have actually done something wrong (and how
to fix it). I'd also love if anyone here has any idea about how soon this bug
fix will be released. I'm not using Java 9. I'm using Java 8. I need my project
to be compatible with all Java LTS, which means at this time that my project
must be compatible with Java 8 and 11.
In my project, all of my packages have {{package-info.java}} with Javadoc and
copyrights in them. When building, I'm getting an error very similar to others'
errors above.
This example error is from the {{licensing-licensor-base}} module:
{code}
[INFO] --- maven-javadoc-plugin:3.0.1:jar (make-javadoc) @
licensing-licensor-base ---
[ERROR] no module descriptor for
io.oddsource.java.licensing:licensing-licensor-base
[ERROR] no module descriptor for io.oddsource.java.licensing:licensing-core
{code}
And this one is from {{licensing-licensor-ui-core}}:
{code}
[INFO] --- maven-javadoc-plugin:3.0.1:jar (make-javadoc) @
licensing-licensor-ui-core ---
[ERROR] no module descriptor for
io.oddsource.java.licensing:licensing-licensor-ui-core
[ERROR] no module descriptor for io.oddsource.java.licensing:licensing-core
[ERROR] no module descriptor for
io.oddsource.java.licensing:licensing-licensor-base
{code}
However, and this is the key difference (I think), in my case, aggregation does
NOT fail (in Java 8*). Aggregation completes, the Javadoc artifact is correct,
and the build completes successfully. In a sense, one could argue that there's
nothing wrong and I can ignore the errors. However, I really don't like seeing
{{[ERROR]}} in my builds, for reasons that I think will be obvious to most
devs. So is this the same bug, and will the fix resolve those errors for me? Or
am I actually doing something wrong here?
(*I have not yet moved on to trying to build on Java 11. So that's TBD.)
The project source can be found at
https://github.com/OddSource/java-license-manager. The current commit
displaying this behavior as of this comment is {{db8c534}}.
