Update Triquetrum to Neon

[cxbrooks]

I attempted upgrading Triquetrum to Neon, but in the end there were problems and the update needed to be backed out.

Hudson was failing to download Gunnar's P2 repo. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=491951#c35

The error message was:

Caused by: org.eclipse.equinox.p2.core.ProvisionException: Communication with repository at https://eclipseguru.github.io/missing-swt-fragments failed. at org.eclipse.equinox.internal.p2.repository.CacheManager.createCache(CacheManager.java:202) at org.eclipse.tycho.p2.remote.RemoteRepositoryCacheManager.createCache(RemoteRepositoryCacheManager.java:66) at org.eclipse.equinox.internal.p2.metadata.repository.SimpleMetadataRepositoryFactory.getLocalFile(SimpleMetadataRepositoryFactory.java:66) at org.eclipse.equinox.internal.p2.metadata.repository.SimpleMetadataRepositoryFactory.load(SimpleMetadataRepositoryFactory.java:88) at org.eclipse.equinox.internal.p2.metadata.repository.MetadataRepositoryManager.factoryLoad(MetadataRepositoryManager.java:57) at org.eclipse.equinox.internal.p2.repository.helpers.AbstractRepositoryManager.loadRepository(AbstractRepositoryManager.java:768) at org.eclipse.equinox.internal.p2.repository.helpers.AbstractRepositoryManager.loadRepository(AbstractRepositoryManager.java:668) at org.eclipse.equinox.internal.p2.metadata.repository.MetadataRepositoryManager.loadRepository(MetadataRepositoryManager.java:96) at org.eclipse.tycho.p2.remote.RemoteMetadataRepositoryManager.loadRepository(RemoteMetadataRepositoryManager.java:61) at org.eclipse.tycho.p2.remote.RemoteMetadataRepositoryManager.loadRepository(RemoteMetadataRepositoryManager.java:53) at org.eclipse.tycho.p2.target.TargetDefinitionResolver$LoadedIULocation.loadRepository(TargetDefinitionResolver.java:288) ... 28 more Caused by: java.net.SocketTimeoutException: connect timed out

Under Mac OS X and RHEL, mvn compile was complaining about:

Oddly, this also happens in the current head with Mars.1, after reverting the pull requests.

For this bug to be close, we need to upgrade Triquetrum to Neon so that the splash screen shows Neon instead of Mars and the binaries need to be created by Tycho on the Hudson Triquetrum site at https://hudson.eclipse.org/triquetrum/job/triquetrum/.

In theory, the plan is to ship the Science2016 Release on Neon, so this has Science2016Release as a mile stone.

Ok, I was able to build in my branch and get the installers for other platforms.

The key thing was to edit the top level pom.xml and remove

<module>org.eclipse.triquetrum.dependencies</module>

However, I messed up the merge some how, so I reverted that pull request.

The issue was that the python work was not compiling.

While running mvn install, the error was:

[ERROR] Cannot resolve project dependencies:

Triquetrum has been updated to use Neon and the Hudson build for Mac shows Neon in the splash screen and works.

We are using the swt fragments from Gunnar's P2 repo. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=491951#c35
