To generate site documentation without running the tests (handy while updating the APTs):
mvn -Dmaven.test.skip=true clean site
To generate javadoc
mvn javadoc:javadoc
To generate javadoc stuffed into a jar file

To create a new non web app Java project (artifact is jar):
mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app
To create a new web app Java project (artifact is war):
mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp
To check the version of Maven:
mvn --version
To run unit tests:
mvn test
To distribute the source code:
mvn assembly:assembly -DdescriptorId=src
To install a jar file on local repo:
mvn install:install-file -Dfile=foo.jar -DgroupId=bar -Dversion=x.y -Dpackaging=jar -DartifactId=blah
To install the oracle ojdbc14_g.jar file on local repo:
Optionally Download the Oracle JDBC driver from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
Q:
cd C:\some\path\to\file\oracle
mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14_g -Dversion=10.2.0.1.0 -Dpackaging=jar -Dfile=ojdbc14_g.jar
Then add a dependency in the pom.xml file similar to the following
<project>
<dependencies>
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14_g</artifactId>
<version>10.2.0.1.0</version>
</dependency>
</dependencies>
</project>
