how to build project after code changes without mvn clean install?

I have a project in eclipse, a java app with appengine sdk and maven as my builder.

The .class files are not refreshed until i launch clean install, so every change i do in code i have to run:

• mvn clean install
• mvn eclipse:clean
• mvn eclipse:eclipse

and then try to launch my app.

Help me please it's really annoying. Thanks
