[cbi-dev] Building platform maintenance branches in offline mode

[Phil Mason <phil.mason@xxxxxxxxxxxx>]

Hi all,

I'm trying to get various R4_x_maintenance branches to build with mvn --offline. The process I'm using is as follows:

Build with a command line like this (actual command is a little more complicated and given at the end of the email):
mvn  -Dmaven.repo.local=/home/pmason/temp-mvn-repo -Declipse.p2.mirrors=false clean verify

That build succeeds and I then archive the maven repo and attempt to rerun the build with 
mvn --offline  -Dmaven.repo.local=/home/pmason/temp-mvn-repo -Declipse.p2.mirrors=false clean verify

which I think should work because everything that is needed for the build to work has already been downloaded and stored in /home/pmason/temp-mvn-repo.

This works as expected with R4_4_maintenance but with R4_3_maintenance it fails with the following message:

> Failed to load p2 metadata repository from location http://download.eclipse.org/egit/updates-3.2: 
> Repository system is offline and no local cache available for 
> http://download.eclipse.org/egit/updates-3.2 -> [Help 1]

The file that causes this problem is eclipse-sdk-prereqs.target and I've looked in tmp-mvn-repo and it contains the three things listed for that location:  org.eclipse.egit.core, org.eclipse.jgit and javaewah with the correct version of each and a p2artifacts.xml.

I've compared the eclipse-sdk-prereqs.target in R4_4 and R4_3 and the only differences seem to be the version numbers of the units.

Is there a way that I can make the build show where it is actually looking for the repository (I'm already using -X and -e)? The trace suggests it is calling SimpleMetadatRepositoryFactory.getLocalFile so I guess that either it can't find the p2Artifact.xml or it is malformed though it looks the same in R4_4 and R4_3.

Thanks in advance for any suggestions you can offer.

All the best

The actual build command I have to use is more like this but I don't think the additions should make a difference:

mvn -X -e --offline --toolchains ~/toolchains.xml  -Pbree-libs -Dmaven.repo.local=~/mvn-repo -Declipse.p2.mirrors=false  clean verify  2>&1 | tee build_log.txt
