maven deploy + nexus failed on bad request

Question

I am experiencing some problems with my build process.

the build is finishing fine and Jenkins starts to upload files to nexus. everything works well, but then it fails for some reason, the weirdest part is that the file that is mentioned to not be uploaded is actually uploaded and i can find it in nexus.

here is the output:

Answer 1

A colleague of mine just ran into the same problem with maven attempting to upload artifacts twice. We found some help in the forums, links included below. Bae's answer did the trick for us:

Try running mvn -Prelease-profile help:effective-pom. You will find that you have two execution sections for maven-source-plugin

[...]

To fix this problem, find everywhere you have used maven-sources-plugin and make sure that you use the "id" attach-sources so that it is the same as the release profile. Then these sections will be merged. Best practice says that to get consistency you need to configure this in the root pom of your project in build > pluginManagement and NOT in your child poms. In the child pom you just specify in build > plugins that you want to use maven-source-plugin but you provide no executions.

Nexus accepts upload but says it failed and Maven release plugin fails : source artifacts getting deployed twice

Answer 2

snapshot and release confliction also results in 400 bad request. The project you are trying to update may be a snapshot like this in pom:

<version>0.0.1-SNAPSHOT</version>

while the repository in settings.xml rejects snapshot. solution:

<version>0.0.1</version>

This also happens the other way round: trying to deploy a release (version has no snapshot) version to a snapshot repository.
