<para>Thanks to maven, building HBase is pretty easy. You can read about the various maven commands in <xref linkend="maven.build.commands"/>, but the simplest command to compile HBase from its java source code is:
<programlisting>
mvn compile
mvn package -DskipTests
</programlisting>
Or, to clean up before compiling:
<programlisting>
mvn clean compile
mvn clean package -DskipTests
</programlisting>
With Eclipse set up as explained above in <xref linkend="eclipse"/>, you can also simply use the build command in Eclipse. To create the full installable HBase package takes a little bit more work, so read on.
