| <section name="Help with Maven Ant Mojos"> |
| |
| <p> |
| The best sources of information are: |
| </p> |
| <ul> |
| <li><a href="https://maven.apache.org/guides/mini/guide-using-ant.html">Apache Maven Guide to using Ant with Maven</a></li> |
| <li><a href="https://maven.apache.org/plugin-developers/index.html">Apache Maven Plugin Developers Center</a></li> |
| </ul> |

| <section name="New Ant Scripts"> |
| |
| <p> |
| Each ant script requires two files, which have to be named following the conventions for ant plugins: |
| <ul> |
| <li>An ant build file |
| <ul><li>[naming convention: <i>basename</i><b>.build.xml</b>]</li></ul> |
| </li> |
| <li>A <i>mapping document</i> which wires the build file into maven's plugin framework |
| <ul><li>[naming convention: <i>basename</i><b>.mojos.xml</b>]</li></ul> |
| </li> |
| </ul> |
| </p> |
| |
| <p> |
| So if you want to add a new <i>foo-bar</i> ant script you would create a <code>foo-bar.build.xml</code> |
| ant script file and <code>foo-bar.mojos.xml</code> mapping document. |
| </p> |
| |
| <p> |
| Both these files should be located in the |
| <a href="http://svn.apache.org/repos/asf/commons/proper/commons-build-plugin/trunk/src/main/scripts/">src/main/scripts</a> |
| directory. |
| </p> |
| |
| <p> |
| If you want to access variables from the component's <code>pom.xml</code> in the ant script |
| then you need to do two things in the <i>mapping document</i>: |
| <ul> |
| <li>Add the <code><requiresProject>true</requiresProject></code></li> |
| <li>Add <code><parameter></code> elements for each of the variables you |
| want to use.</li> |
| </ul> |
| </p> |
| |
| </section> |
| |
| <section name="Goal Prefix"> |
| |
| <p> |
| This plugin uses <code>commons</code> as the goal prefix. So if you add a new <code>foo-bar</code> |
| goal, then it can be executed on the command line using <code>mvn commons-build:foo-bar</code>. This prefix |
| is defined in this plugin's |
| <a href="http://svn.apache.org/repos/asf/commons/proper/commons-build-plugin/trunk/pom.xml">pom.xml</a>. |
| </p> |
| |
| </section> |
| |
| <section name="Modifying Existing Scripts"> |
| |
| <p> |
| Not alot to say about this except, if you need access to additional variables from the component's |
| <code>pom.xml</code> in the ant build script then you will need to define additional <i>parameters</i> |
| for these in the associated <i>mapping document</i>. |
| </p> |
| |
| </section> |
| |
| <section name="Debugging"> |
| |
| <p> |
| The <i>message level</i> for ant is <i>info</i> by default. Running the plugin goal using a message |
| level of <i>debug</i> can help in discovering problems - for example: |
| <source><![CDATA[ |
| mvn commons-build:jira-page -DantMessageLevel=debug |
| ]]></source> |
