Maven builds on file changes

Question

Is there anything already out there that would help with either / both of following?

• Perform a Maven install when a file within that module changes
• Perform a Maven install on the module and its dependencies if they have changed

I'm pretty sure I've heard of a Maven option to build dependencies as well but struggling to find anything from Googling...

Perhaps this isn't going to be Maven specific but instead involve a file watching tool that is OS specific, if so I would be interested in hearing about tools for Windows (XP).

Answer 1

Even though the answer comes late, I was looking for the same thing and I found https://github.com/rzymek/watcher-maven-plugin . Maybe someone else will be looking for the same thing.

Answer 2

I tried @Adrian's solution, but I couldn't get it working.

I found this maven package, https://github.com/fizzed/maven-plugins#watcher-fizzed-watcher-maven-plugin , that will watch for file changes, and I was able to get it working pretty quickly.

Answer 3

To building a module and its dependencies, use: mvn -pl :module -amd

Automated builds are usually triggered from a version system like subversion or git. Then you can use continuous integration tools like Jenkins.

There's also mvn reactor:make-scm-changes, which detects what modules have local changes vs. the configured scm system.
