The Maven team is pleased to announce the Eclipse plugin 1.5 release!

http://maven.apache.org/reference/plugins/eclipse/

The Maven Eclipse plugin generates eclipse configuration files, such as .classpath, .project as well as
allowing Maven to execute as an external tool within Eclipse.

Fixed in this version

o Absolute paths were being generated in .classpath. Relative paths are now output

Note that this plugin has been tested with Maven 1.0 rc1. Using it with
another version of Maven is at your own risk! :-)

You can download and install the Eclipse plugin by using

maven -DgroupId=maven -DartifactId=maven-eclipse-plugin -Dversion=1.5 plugin:download

Have fun!
