Maven release process fails randomly when trying to push to sonatype

[markpatton]

Error in logs releasing pass-core:

Error: [ERROR] Failed to execute goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.13:deploy (injected-nexus-deploy) on project pass-core-main: 
Execution injected-nexus-deploy of goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.13:deploy failed: A message body reader for Java class
 com.sonatype.nexus.staging.api.dto.StagingProfileRepositoryDTO, and Java type class 
com.sonatype.nexus.staging.api.dto.StagingProfileRepositoryDTO, and MIME media type text/html was not found -> [Help 1]

This happens after

[INFO] [INFO]  * Closing staging repository with ID "orgeclipsepass-1046".
[INFO] 
[INFO] Waiting for operation to complete...
[INFO] ..................
[INFO] 
[INFO] [INFO] Remote staged 1 repositories, finished with success.

Also note that despite the above failure, in every case the deployment to maven central has succeeded.

These issues seem to be the same:

• https://issues.sonatype.org/browse/OSSRH-51097
• https://issues.sonatype.org/browse/OSSRH-93028

As can be see from the first issue linked https://issues.sonatype.org/browse/OSSRH-51097, this is still happening to folks now. It is caused by heave load on there servers.

I spent a bunch of time digging into the source code. The maven plugin uses the Nexus 2 branch of https://github.com/sonatype/nexus-public. The REST API is based on Jersey. I wanted to see if the interactions could be made more reliable, but the interactions are buried in various abstractions. There are some timeouts that could be increased. See https://help.sonatype.com/repomanager2/staging-releases/configuring-your-project-for-deployment.
We should try setting stagingProgressTimeoutMinutes to something like 10 minutes, the default is 5.

One way to make things better is having the release process be able to be easily restarted.
