P2 repositories intermittent failures [message #1796597]

Hello,
My target platform was failing to reload for many days. It started working, worked for a day, and started failing again. It is very frustrating not being able to do maven tycho builds from the command line OR reload the target platform within Eclipse OR even update eclipse.

We are trying to hit http://download.eclipse.org/releases/photon/.

Is there any way to become completely independent of the eclipse P2 repositories?? From what I read, even mirroring won't help because that only mirrors the artifacts and not the xml files. This is having a serious impact on my development team.

Thanks.

My suggestion is to set up a Nexus OSS repository and proxy the repositories. Vogella has a tutorial with the details.

Your developers configure their ~/.m2/settings.xml to reference the proxy.

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <mirrors>
    <mirror>
      <id>nexus-eclipse-photon</id>
      <mirrorOf>photon,eclipse-photon,http://download.eclipse.org/releases/photon</mirrorOf>
      <url>http://nexus.example.com:8081/nexus/content/repositories/eclipse-photon</url>
      <layout>p2</layout>
      <mirrorOfLayouts>p2</mirrorOfLayouts>
    </mirror>
  </mirrors>
</settings>

Thanks Brian. I will try and execute the steps in that tutorial.

Eclipse software updates, target platform within Eclipse, and maven eclipse tycho builds were all working fine. Suddenly they all stopped working. Nothing else has changed. I don't know if the eclipse servers are having issues over the last 24 hours.

It must have been an issue with the Eclipse servers. It all started working again. Thanks for your pointer about how to build my own p2.

There was some snafu with download.eclipse.org. It's worth checking the cross-project-issues-dev mailing list if it happens again.

Use of a proxy will shield you from such an outage, should result in much faster build times for your developers, and reduces the load on the Eclipse Foundation servers. It's a win-win-win all around, IMHO.
