Change default output directory

[willhains]

...to ${project.build.directory}/generated-sources/package-info,
since this is where Maven and IDEs expect generated sources to be.

Resolves #7

@willhains I think the output directory must not include the trailing /package-info, otherwise the generated sources are not in the correct package (all preceded with package-info then) and are also not picked up by IntelliJ correctly. I've set it manually now via

<outputDirectory>${project.basedir}/target/generated-sources</outputDirectory>

and now IntelliJ is able to pick @NonNull annotations there.

@neiser This PR has not been merged. Are you using the plugin with this PR applied?

Please note that @bohnman is no longer maintaining this project (see discussion in #6), so with his permission I created a fork with these changes applied, and published it to Central.

Can you try changing your groupId to io.github.willhains? If it still doesn't work, please create an issue in my fork.

Fwiw, I'm using the forked version of this plugin in my project UDTopia, and it works as expected. Both Maven and IntelliJ are picking up the generated sources.

@neiser Postscript on above: There is a related change in #8 which tells Maven (and therefore IntelliJ) to treat the generated package-info directory as a source root. Perhaps this is the issue you are facing.

Both #8 and #9 are included in my fork.

Hope this helps! :)
