Can I trigger a Jenkins job using a Maven dependency?

Question

I have multiple Jenkins Jobs built using Maven:

Job 1: Builds WebApp and deploys war to artifactory
Job 2: Builds Core and deploys jar to artifactory

WebApp has a dependency on Core.

Is it possible for Jenkins to parse the POM, see that WebApp has this dependency on Core and thus triggers Job 2 before building WebApp? This would ensure WebApp uses an up-to-date, latest Core.jar

I can achieve this mechanism via the Jenkins Parameterized Trigger plugin's Pre-Steps feature but I would ideally like to handle this from the POM.

Thanks.

Answer 1

Yes there is.

1. you need to set up the jobs as Maven Job

2. In Job A select the checkbox: Build whenever a snapshot dependency is build.

Apparently this only works, if the dependency is a snapshot dependency.
