Maven deploy multi module project only if all modules build successfully

Question

I have a maven multi module project with several modules. I want to deploy them (mvn deploy) only if they all pass a full mvn install (which includes the tests).

Currently, I run a mvn install on the project. If all modules pass, I run mvn deploy to do the deployment. The problem I see is the waste of time calling mvn twice (even if I skip tests on the second run).

Does anyone have an idea on this?

EDIT: I have learned that using Artifactory as a repository manager and the maven-artifactory-plugin with your maven setup will add the atomic deploy behaviour to the mvn deploy command. See the Build Integration section in the Artifactory documentation.

Answer 1

Take a look at the deployAtEnd parameter of Maven Deployment plugin: http://maven.apache.org/plugins/maven-deploy-plugin/deploy-mojo.html

Answer 2

This is a bit tricky. Maven is not atomic when it executes the build life-cycle. So a broken set of artifacts may end up in a repository.

One solution I know is Nexus Pro: http://www.sonatype.com/Products/Nexus-Professional/Features - it allows you to promote builds or define certain repos as staging. So only verified versions get promoted to be used. Maybe artifactory has something similar - I just don't know.

If that solution is too expensive you probably need to create a cleanup build or profile to remove artifacts that where already uploaded. My first guess would be to write a Maven plugin to use the the proxy remote API or maybe the maven features are already sufficient. But since deploy means update the meta-data xml files too I dont think there is a delete - not sure on this either.
