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,

To solve this problem here is what I did:
Install Groovy Monkey for Eclipse
Created a Bean Shell Script "UpdateMavenDerived_Beanshell.gm" to mark any directory named target as derived.

-----------Cut below here for script--------------

/*
 * Menu: Find System Prints > Beanshell
 * Script-Path: /GroovyMonkeyScripts/monkey/UpdateMavenDerived_Beanshell.gm
 * Kudos: Bjorn Freeman-Benson & Ward Cunningham & James E. Ervin
 * License: EPL 1.0
 * LANG: Beanshell
 * DOM: http://groovy-monkey.sourceforge.net/update/plugins/net.sf.groovyMonkey.dom
 */
out.println("Setting target directories to derived status.");
var projects = workspace.getRoot().getProjects();
for ( var i = 0; i < projects.length; i++) {
    var project = projects[i];
    if (project.isOpen()) {
        out.println("Project: " + project.getName());
        var members = project.members();
        for ( var j = 0; j < members.length; j++) {
            if (members[j].getName().equals("target")) {
                out.println("setting derived status on: "+ members[j].getFullPath());
                members[j].setDerived(true);
            }
        }
    }
}

I had some issues because some solutions here only work for some views, so I made an illustrated summary.

_{Tested in Eclipse 4.4 (Luna), should work like this since 3.7 according to other answers here.}

Package Explorer

Package Explorer View Menu → Filters... → check Name filter patterns and input target.

Be careful, this will hide all folders and files named target, not just the default maven build directory! The Project Explorer view has a better option without this issue.

Package Explorer Menu Package Explorer Dialog

Project Explorer

Project Explorer View Menu → Custom View... → search for "maven" and check Maven build folder.

Checking this option hides the build directory as defined in the projects pom.xml configuration.

Did you try configuring the "Java Element Filters" option dialog box, (through the top-right arrow of the project explorer) ?

If needed, you can define your own ViewerFilter

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".

Reconfigure "clean" in Maven not to delete target directory:

<plugin>
    <artifactId>maven-clean-plugin</artifactId>
    <configuration>
        <excludeDefaultDirectories>true</excludeDefaultDirectories>
        <filesets>
            <!-- delete directories that will be generated when you 
                 start the develpment server/client in eclipse  
            -->
            <fileset>
                <directory>target</directory>
                <includes>
                    <include>**/*</include>
                </includes>
            </fileset>
        </filesets>
    </configuration>
</plugin>
