Maven

Maven is a Java project management tool.

• Maven is similar to Ant but simpler.
• A Maven project is any directory with a project.xml file in it

• project.xml defines the project object model (POM)
• maven.xml defines goals

The repository holds common libraries. These libraries must be installed into the repository. Under windows, the repository is normally found in:

c:\Documents and Settings\<User>\.maven\repository

Maven uses plugins to execute goals. Within a project's directory, a plugin is called as follows:

mavin <plugin>:<goal>
e.g. maven java:compile

The plugins are written in Jelly

If a plugin has a default goal, it can be executed by:

maven <plugin>

• Constants can be defined in %HOME%/build.properties
• They are referenced by ${constant.name}

• Download maven and follow installation instructions
• Set the environment variable MAVEN_HOME to
• Create a local repository by running

%MAVEN_HOME%\bin\install_repo.bat %HOME%\.maven\repository

Installing jars

You can define where the remote repository is held by changing the maven.repo.remote value in project.properties

maven.repo.remote = http://www.ibiblio.org/maven

http://www.ibiblio.org/ is an open source maven repository,

• maven.xml - contains project specific goals, preGoals and postGoals

Tell Eclipse where the Maven repository is by setting the MAVEN_REPO variable in Window→Preferences→Build Path→Classpath Variables. On Belfast the repository is in c:\java\maven-v.vv\repository

You can change into any maven-enabled project directories and type:

maven eclipse

and a .project and .classpath will be create automatically.

Import into Eclipse and rebuild
