I use Tycho already a couple of months now. But yesterday I got an issue during building my application with Tycho. On first look, it was a repository that was down. But today I have the same issue and not only on the general Eclipse 4.7 repo but on other repo's.
I use those repositories in my target file:
<repository location="http://download.eclipse.org/eclipse/updates/4.7/" />
<repository location="http://download.eclipse.org/technology/epp/packages/oxygen" />
<repository location="http://download.eclipse.org/nattable/releases/1.5.0/repository/"/>
<repository location="http://download.eclipse.org/releases/oxygen/"/>
<repository location="http://download.eclipse.org/nebula/snapshot/"/>
<repository location="http://download.eclipse.org/nebula/incubation/snapshot/"/>
<repository location="http://download.eclipse.org/nattable/snapshots/latest/repository/"/>
The error that I'm getting when I build it on my dev and on my build server is:
[ERROR] Failed to resolve target definition D:\Jenkins\workspace\Client Staging\neon\neon.target: Failed to load p2 metadata repository from location http://download.eclipse.org/eclipse/updates/4.7/: Unable to read repository at http://download.eclipse.org/eclipse/updates/4.7. HTTP Server 'Bad Gateway' : http://download.eclipse.org/eclipse/updates/4.7/R-4.7.3a-201803300640/content.xml.xz: HttpComponents connection error response code 502. -> [Help 1]
Does someone know how to fix this? I need this to build my application on an automatic way and deploy the application on different locations.
The full Maven errors looks like:

The problem was an unstable p2 repository. Didn't changed anything and today it's working just fine.
