I\'m using maven 2.0.9 with Eclipse 3.3.2.
I\'m used to launching a fresh build once per day by a mvn clean install.
Then, if I refresh my Eclipse project,
The maven plugin does not hide away the target directory. It does however use the maven target folders to configure eclipse. So target/classes and target/test-classes are used by eclipse, and eclipse filters these folders out. This is done by "mvn eclipse:eclipse" as well as by the m2eclipse plugin. What is left visible is everything in the target directory besides these two folders (the generated jar file for example).
You can create a filter for the package explorer, but that will not influence the "open resource".
