Re: [tycho-dev] build failures with latest snapshot

Optional/greedy makes target platform (and thus build result) unstable.
I think Tycho should either always ignore optional dependencies or
require them.

I would at least want the resolver to always be greedy and add
optional dependencies to the target if they are available. I guess it
would be too harsh to fail by default if an optional dependency can't
be resolved and not all optional dependencies are required at
compile-time anyways.

Do you mean treat all optional dependencies as required during during

Thanks for the responses. I'll update our build accordingly.

For the record, here is the bug for handling optional dependencies
during compile-time:

  351842: builds fails when implicit target is used and optional
dependency is specified as non greedy in p2.inf
  https://bugs.eclipse.org/bugs/show_bug.cgi?id=351842

I would prefer if optional dependencies were resolved by default and
didn't need to be specified in the build.properties.

For optional dependencies, I think it is common to have optional runtime
dependencies that are required for compilation, so I think we need a way
to decouple compile- and run- time dependencies. Currently,
jars.extra.classpath can be used to express compile-only dependencies,
but I am not sure if this is the best solution going forward.

For feature id matching bundle ID... just don't do it. I realize this
will cause migration problems, but this never worked reliably
before and there are no plans to support artifactId != bundle/feature ID
in Tycho going forward (see [1]).

Since the latest Tycho snapshot release Mylyn builds are starting to
fail. From a quick glance, there are two changes: Optional
dependencies are no longer resolved (we use implicit targets in
nightly builds) and Maven artifact ids are now expected to match
feature and plug-in ids.

Concerning the optional dependencies, is the Tycho behavior going to
change again or do these now need to be marked as greedy in all
manifests (assuming that's the cause of the problem)?

Changing artifact ids is easy but what is the recommended strategy in
case a plug-in and feature use the same id?

Thanks,

Steffen
