+1 for ignore with a possible compromise that if you create an bundle (OSGi) project then it could be set to warning. Also note that it seems the API tooling team is trying to get in tooling that would flag cases where you evolved the code but not the package version number so John, you second concern should be addressed.

There is a pretty large user community that is happy to version only at the plugin level, so it's not clear that the absence of package versions is wrong. The problem I see with the quick fix is that people may run it once to get rid of the warning, and then fail to evolve the version number as the package changes. I think it's better to have no package versions than to have package versions that are never incremented in a meaningful way. Also, x-internal packages generally don't need version numbers.

If we use something other than IGNORE, there will be billions of warnings, keep that in mind. I personally think that versioning is an advanced concept and we should becareful how we display that information to beginners. In PDE, we have to be very careful and not alienate beginners. If we want to enforce the rule of versioning everything, maybe this is something we can do in a future version of Eclipse.

Re: [equinox-dev] Fw: [Bug 214801] [api tools] consider Export-Package as API
the EMF issue is that they use some stuff from the org.eclipse.core.runtime bundle. That bundle is tied directly to org.eclipse.osgi. EMF needs to get off the old runtime stuff. This is independent of how they spec their dependencies. We should IMHO spec package versions regardless of whether or not we use import package. Others cannot use import package safely if we do not spec them. p2 uses import package alot and we will have to start specing versions. We already have tooling place that tells us about api changes relative to another version etc. The trick right now is to get the version number management in place and at the package level. the API tools team has commented that this should be doable but they have alot of other stuff going on and need to assess the priorities.

You need to, as part of the release process, use tooling, like japitools, to examine each package for changes, including non-backwards compatible changes. Then, at the end of the release, the package and bundle version numbers can be properly increased. We do this in the OSGi release process.
