Configuring Maven to run within Eclipse.

1. Eclipse has an embedded version of Maven which you can use. Assuming that you want to use Maven within Eclipse and outside of it, download Maven from http://maven.apache.org/download.cgi, extract it and set the M2_HOME environment variable such that it points to your local Maven installation directory.

2. Set JAVA_HOME environment variable so that it points to the JDK which you want to use.

3. Append %JAVA_HOME%\bin and %M2_HOME%\bin to the Path so that the jdk and mvn executables can be executed from anywhere.

4. Now open an Eclipse Workspace and go to Window > Preferences > Maven > Installations. If you want to use your standalone installation instead of using the embedded one, you can change it here.

5. If you have a specific Maven settings file which you want to use, then dump that settings.xml file under the .m2 folder of your User home directory.

6. Once this is done, you can easily use Maven from within eclipse.(File > Import > Maven > Existing Maven Projects) or create a new one (File > New > Maven > Maven Project). Once you have a project in your workspace, you can run different Maven goals on it by right clicking on the Project and selecting what you want from the Run As option.
