this looks like it's from ant; we would need more context (links to full logs) to be able explain what this means and how to get rid of the warning.
Maybe Krzysztof can chime in here.

One thing I can recommend is to set property tycho.localArtifacts=ignore [1] for full builds.

Maven has the behaviour to include artifacts installed into the local repo by previous builds into the dependency resolution space.
While this is required for partial rebuilds of multi-module builds, it may cause unexpected locally installed versions of artifacts being picked by the p2 resolver.
Set this property on the commandline (-Dtycho.localArtifacts=ignore) or globally in settings.xml so that artifacts installed into the local repo are not considered by the p2 resolver.

Also, if you want more precise control over the binary target platform, using a PDE target file will let you pick which IUs from which repo you want to be visible to the build [2].
Just adding the whole p2 repo in pom.xml will make any IU in that repo available to the build which may not be what you want.

Another thing, I have some doubts whether the eclipse platform build is currently cycle-free in the sense that there are artifacts being built from source but there are also older versions of the same artifact in the target platform.  Example:

org.eclipse.equinox.concurrent is being built in the platfrom build http://git.eclipse.org/c/equinox/rt.equinox.bundles.git/tree/bundles
, but it's also referenced binary in http://git.eclipse.org/c/platform/eclipse.platform.releng.aggregator.git/tree/eclipse-parent/pom.xml?h=R4_2_maintenance as apart of the ECF p2 repo 
http://download.eclipse.org/rt/ecf/3.5.6/site.p2 

This is something tycho can't fix and I wonder if there is a bug open in CBI for this?

Jan

Besides solving this specific issue, I'd appreciate any quick tips on how to make builds more repeatable .... across machines, environments, etc. For one example, occasionally I see messages in the log that says 

warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds 

What? 

I've also heard people say things like "yeah, sometimes if things act funny I have wipe out my local repos and start fresh and then its ok". That's certainly understandable for the phase we (Platform) are in, but is that a common practice? Any one have any pointers to how to make your builds more reliable and repeatable? 

Thanks,

Hi Everyone,

I'm a little stumped on Bug 398201 [1] an was hoping maybe someone on this list might have any ideas.

What's strange about this issue is that when I run this same build on my laptop it works just fine. I'm using maven 3.0.4 and Oracle JDK 1.6 (also tried 1.7). Strangely when building on build.eclipse.org we encounter the issue described in Bug 398201. It seems to have issues resolving 2 packages:

[ERROR] Bundle org.eclipse.equinox.ip - Missing Constraint: Import-Package: javax.servlet; version="2.1.0"
[ERROR] Bundle org.eclipse.equinox.ip - Missing Constraint: Import-Package: javax.servlet.http; version="2.1.0"


I've even tried copying over my JDK from my laptop to build.eclipse.org but the failure persists. The fact that it works on my laptop but not on build.eclipse.org makes me suspect environment but other than maven and JDK I'm not sure what else could be different.
