[jbosstools-dev] Upcoming changes in Target Platform: Kepler RC3

[Mickael Istria]

Here is the most interesting ouput I got:

mistria at mistria--rh:~/git/p2diff/org.eclipse.equinox.p2.example.p2diff.packaging/target/products/org.eclipse.equinox.p2.example.p2diff.product/linux/gtk/x86_64$ ./p2diff -mode=ignoreVersions http://download.jboss.org/jbosstools/targetplatforms/jbosstoolstarget/4.30.5.Alpha6-SNAPSHOT/REPO file:/home/mistria/git/jbosstools-target-platforms/jbosstools/multiple/target/jbosstools-multiple.target.repo/
< org.eclipse.update.core [3.2.600.v20130514-1341]
=== Summary ===
http://download.jboss.org/jbosstools/targetplatforms/jbosstoolstarget/4.30.5.Alpha6-SNAPSHOT/REPO contains 1 unique IUs
file:/home/mistria/git/jbosstools-target-platforms/jbosstools/multiple/target/jbosstools-multiple.target.repo/ contains 0 unique IUs

It's interesting, but in this specific case, it doesn't provide much value.
Here is what we would have noticed if we have used it earlier:

< org.eclipse.ecf.provider.filetransfer.httpclient [4.0.300.v20130309-0714]
< org.eclipse.persistence.jpa.jpql.source [2.5.0.v20130425-368d603]

> org.apache.poi [3.9.0.v201303080712]
=== Summary ===
http://download.jboss.org/jbosstools/targetplatforms/jbosstoolstarget/4.30.5.Alpha5/REPO contains 3 unique IUs
http://download.jboss.org/jbosstools/targetplatforms/jbosstoolstarget/4.30.5.Alpha6-SNAPSHOT/REPO contains 2 unique IUs

Which is more interesting (notice the httpclient removal). So it looks 
like this p2 diff tool can definitly help to anticipate some bugs as it 
allows to spot changes in transitive dependencies.

Cheers,
