<p>We need the ability to bind a Mojo to a custom LifeCycle.</p>

<p>Our specific use case is to be able to perform extra tasks during release that need to occur at times other than the small window provided by the maven-release-plugin's run-preparation-goals and run-perform-goals phases. In particular we need Mojos to execute during the scm-commit-development and scm-commit-rollback phases.</p>

<p>So we need the ability to bind our plugin's Mojos to those phases.</p>

<p>I would think that there are probably many other use cases, for other custom LifeCycles, not only for the release-plugin.<br />
A mechanism for binding Mojos to custom LifeCycles provides a much cleaner mechanism for plugins like the release-plugin that are aware that they need to integrate with other plugins.</p>

<p>I would like to propose a syntax similar to:</p>
<table class="wysiwyg-macro" data-macro-name="code" style="background-image: url(/plugins/servlet/confluence/placeholder/macro-heading?definition=e2NvZGV9&amp;locale=en_GB&amp;version=2); background-repeat: no-repeat;" data-macro-body-type="PLAIN_TEXT"><tr><td class="wysiwyg-macro-body"><pre>
&lt;plugin>
	&lt;groupId>com.yarris.maven.plugins&lt;/groupId>
	&lt;artifactId>maven-subclipse-tags-plugin&lt;/artifactId>
	&lt;version>1.3&lt;/version>
	&lt;executions>
		&lt;execution>
			&lt;-- Bind to the release-plugin:scm-commit-development phase. -->
			&lt;phase>org.apache.maven.plugins:maven-release-plugin:scm-commit-development&lt;/phase>
			&lt;goals>
				&lt;goal>update-property&lt;/goal>
			&lt;/goals>
		&lt;/execution>
	&lt;/executions>
&lt;/plugin>
</pre></td></tr></table>
<p>where the groupId and artifact binding of the phase follow the same defaulting process at that used to define dependencies. That is the above binding could be rewritten as:</p>
<table class="wysiwyg-macro" data-macro-name="code" style="background-image: url(/plugins/servlet/confluence/placeholder/macro-heading?definition=e2NvZGV9&amp;locale=en_GB&amp;version=2); background-repeat: no-repeat;" data-macro-body-type="PLAIN_TEXT"><tr><td class="wysiwyg-macro-body"><pre>
&lt;-- Bind to the release-plugin:scm-commit-development phase. -->
&lt;phase>maven-release-plugin:scm-commit-development&lt;/phase>
</pre></td></tr></table>
<p>or even</p>
<table class="wysiwyg-macro" data-macro-name="code" style="background-image: url(/plugins/servlet/confluence/placeholder/macro-heading?definition=e2NvZGV9&amp;locale=en_GB&amp;version=2); background-repeat: no-repeat;" data-macro-body-type="PLAIN_TEXT"><tr><td class="wysiwyg-macro-body"><pre>
&lt;-- Bind to the release-plugin:scm-commit-development phase. -->
&lt;phase>release:scm-commit-development&lt;/phase>
</pre></td></tr></table>
<p>The other (IMHO poorer) option would be to include the LifeCycle of the release-plugin as part of the Maven core.</p>

<p>Without this proposal we will</p>
<ul>
	<li>need to continue to maintain a version of release-plugin that includes extra phases required to simulate this behaviour</li>
	<li>not be able to open-source the subclipse-tags-plugin (which is of benefit to anyone using Eclipse+Subversion) as it needs the hooks provided by our hacked version of the release-plugin.</li>
</ul>

<p>I'd really like to use a base version of the release-plugin and I'd really like to be able to provide the subclispe-tags-plugin to the community.</p>
