Re: [tycho-user] Unable to read repository at http://download.eclipse.org/rt/eclipselink/updates
|
http://download.eclipse.org/rt/eclipselink/updates/compositeContent.xml
lists several zip files as child repositories. this won't work.
It was probably only hidden up to now by the fact that p2 silently ignores broken child repositories by default.
For build reproducibility reasons, tycho has chosen to fail the build in this case [1].
You can override it using -Declipse.p2.atomic.composite.loading.default=false but I don't think that's a good idea.
I think you should open an eclipselink bug for this.

Jan

But is tycho unable to use compressed Update Sites?

I think tycho cannot use Target platform as zip.
only updates sites are supported : http://wiki.eclipse.org/Tycho/Target_Platform

Hello,
today I have a strange problem.
I created a hello world sample app with eclipse, added a target file and configure tycho to build this project as plugin. Eclipse could resolve the target file in a fresh workspace without problems, but tycho throws ...

Is something different in this P2?
I attach my sample project, but you could also create it in 5 minutes with eclipse.
Thanks
Kai
