Re: [cbi-dev] CBI Rebasing platform to M7

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

org.eclipse.help.base currently requires
Lucene 2.9 at compile time. However, at runtime it is possible to use it
with Lucene 3.5. There is only one help class that does not work with Lucene
3.5, and that code path can easily be avoided depending on how you configure
Lucene. This is a short term situation for the Juno release. Eclipse Platform
ships with Lucene 2.9, but the Orion project requires Lucene 3.5 for other
reasons. They both use the help system so the wider runtime dependency
was needed. After Juno we intend to move the platform up to the newer lucene
version. Details are in bug 340563 [1].

So, if you could force the build to
use Lucene 2.9 at compile time, while still allowing the wider runtime
dependency, that would be the ideal solution for Juno.

Subject	[cbi-dev] CBI Rebasing platform to M7

Hi Everyone,

I'm rebasing the CBI build to M7 and ran into an issue below. After doing
some searching I discovered that newer versions of org.apache.lucene has
a new function that needs to be implemented which org.eclipse.help.base
is not implementing as far as I can tell. Doing a bit more searching I
discovered a commit [1] where the upper bound for org.apache.lucene was
removed. If I revert this change I can proceed with the build.

I guess the CBI build pulls from orbit a version of org.apache.lucene that
is too new so commit [1] causes us to no longer be able to build.

I was wondering what the best course of action here should be? 
Should platform upstream revert this change?
