Re: [cross-project-issues-dev] [epp-dev] Photon aggregation jobs are stu

New build is no better. It seems that simrel is processing jars from platform in some ways. The sums of plugins from platform don't match those from contributed repository.

I have no idea why the aggregator is doing that. I'm still investigating. 

I guess we won't be able to release M7 @ 10am EDT.

See below the debug info I gathered.

A new aggregation build is running with the latest version of the aggregator (incl Alex's patch). 

We need to talk about the future of the Eclipse Desktop IDE simrel tooling, but let's build M7 first ;) 

Thanks.

I cannot resist to mention that this kind of bugs shows how obsolete and not-so-well maintained and regularly erroneous in its understanding of p2 is the SimRel aggregator compared to Tycho; and that building the Simultaneous Release on top of such bugged and unpopular software is a major risk for our community, and causes always the same individual (fortunately often courtesy of the Foundation mostly, but not only) to spend major efforts in cutting the fire.

The only sustainable path for SimRel is to move away from CBI aggregator and a lot of related Ant scripts and start building on state of art and well used and maintained Maven and Tycho.
Driven by my concerns about CBI aggregator, I've provided several related usable pieces of work on this topic:

* a pom.xml can already be used to build simrel with a plain `mvn clean verify` (delegating to CBI aggregator so far)
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=500769 contains proposals of a migration to Tycho and some discussions.

I'd gladly welcome help to move forward with it.

In the meantime, good luck to those who still have the patience to fix the CBI aggregator ;)
