we migrate from Artifactory a week ago, and we were using Artifactory Deploy Plugin to post build deploy our artifact.

As we went to Nexus, we now use the Post build deploy feature of embedded Maven Project plugin.

Everything seems to works, but the maven-metadata.xml are not updated when artifacts are uploaded.

I run many tests, and mining into logs (as we got a Apache Front of our Nexus), and i saw that the plugin download (twice) the maven-metadata from Nexus, and upload one just after (that the normal behaviour - except the twice thing).

After re-reading the apache logs, the metadata is simply not deployed. The log show the metadata of the artifact version, not the mave-metadata.xml with all version. We have tested without nexus, by deploying in a file system. The behaviour is the same, and the issue is still here. So Nexus is not involved.

But when i look into the file (maven-metadata.xml) the new snapshot version is not present. As our integration process rely on this metadata, we are some kind of blocked (the workaround is to schedule a task in Nexus to rebuild metadata, but this is not "live")

Am I missing something ?

Here is the apache log :
