Build ID: Eclipse 3.7 (Indigo) Steps to reproduce: 1.) Install Eclipse Platform Runtime Binary, eg http://download.eclipse.org/eclipse/downloads/drops/R-3.7-201106131736/ download.php?dropFile=eclipse-platform-3.7-win32.zip 2.) Launch Eclipse 3.) Help > Install New Software... pick http://download.eclipse.org/releases/indigo 4.) Install "Mobile and Device Development > Target Management Terminal" --> Following Lucene optional bundles are installed silently as a side-effect: org.apache.lucene.highlighter_2.9.1.v20100421-0704.jar org.apache.lucene.memory_2.9.1.v20100421-0704.jar org.apache.lucene.misc_2.9.1.v20100421-0704.jar org.apache.lucene.queries_2.9.1.v20100421-0704.jar org.apache.lucene.snowball_2.9.1.v20100421-0704.jar org.apache.lucene.spellchecker_2.9.1.v20100421-0704.jar
Created attachment 199494 [details] patch v1, adding p2.inf to make dependencies non-greedy The underlying problem for installing optional runtime dependencies as a side-effect has been discussed on bug 247099. In fact the p2 publisher will be changed in the Juno timeframe, to no longer cause this. For the Indigo time frame, it is possible to explicitly mark optional runtime dependencies non-greedy by adding a p2.inf file. This approach is in-line with the approach on bug 247099, it just makes the fix explicitly which will be done implicitly in the future. Attached patch adds the necessary p2.inf for org.apache.lucene .
+1 Martin, feel free to commit and release. :)
IMHO, this is a "breaking" change ... I'm sure you can imagine some might depend on this behavior. But, I don't know of anyone who does, or anyone who would complain. But ... at some point ... this "potentially breaking change in maintenance release" should be announced on cross-project, with some indication of how to get "old" behavior (i.e. refer to those optional bundles explicitly in feature) and give community a chance to complain ... just in case. To be clear, I am not 'objecting' to this change (though, don't like it much ... I did open bug 349515 so the help system would stop depending on the umbrella lucene bundle ... which is a better fix, imho, but, again, I know there is a real problem here and I'm not that picky how fixed ... just commenting and cross referencing bug entries).
(In reply to comment #3) > IMHO, this is a "breaking" change ... I'm not sure it really is. The umbrella bundle has optional dependencies on the other bundles. This is stated as optional in the manifest. Any client that rely on any optional API must be prepared that it's not available all the time. If not it's a violation of the optional contract (IMO). Clients using Import-Package won't notice because p2 will install the bundles for them automatically.
Is this required for Indigo SR1? Or will Juno suffice? I ask since I do not see it released to a build yet? Waiting on anything? Change your mind?
I think this will be indirectly fixed by bug 368999, in Juno M5. So, will mark this as "won't fix" since patches not applied, no change to Lucene bundle directly, and since won't be fixed for Indigo. Also, see bug 365693 which might complicate things?
Feel free to reopen if I have misunderstood anything.
