How this problem can be fixed? Which branch are you building ? Can you pastebin the full log ? My guess is you built just in the time between clean of the staging area was done so the composite site don't have these bits yet - but hard to say without knowing when and what you built exactly. /max

The problem is org.jboss.tools.tests is not part of http://download.jboss.org/jbosstools/updates/nightly/core/trunk/plugins/

Pushing process can be implemented different way to avoid this issue, I saw it many times and it is a bit annoying. I remember we spend some time with Nick to tackle it, but problem seems still here. Idea behind this fix is really simple: 1. Leave old published bits as is on the server side and just upload new ones 2. Update compositeArtifacts.xml first and include uploaded update site from step 1 3. Update compositeContent.xml: include new uploaded update site from step 1 and remove oldest one 4. Update compositeArtifacts.xml and remove oldest one 5. Remove oldest update site folder Note there are no operations related to renaming/moving previously uploaded update sites and that the key point to have previously uploaded sites available while new one is in uploading stage. It should significantly reduce amount of errors because we keep two update sites for each jbosstools-module, so at least one update site is always available through composite update site for module. There could be still problems for builds with slow connection, but connection should be slow enough to live through at least two builds for jbosstools module. This could be implemented as maven plug-n and number of builds to keep in composite could be a good candidate for configuration parameters. It is not really critical but nice to have.

Considering it takes couple hours to execute and you have to do that again and sometimes again until it works, it is not really convenient.

bing! builds would stop failing so often.

In fact for the future we can even save space by publishing only changed bits (need to fix qualifier for features/plugins) and it would let to: 1. Decrease time for syncing with download.jboss.org; 2. Have installation history actually working and let people use nightly updates and roll back to previous version if something is wrong; 3. Increase speed of local/jenkins builds, because no more full downloads for dependencies

This sounds like something we should get done during the current "down time" before we're in the middle of a new Alpha1 code freeze cycle. Denis, is there an existing JIRA for this, or would you like me to open one?
