OK, I'm answering my own question. Found the maven code that evaluates the
expressions, and it seems that the string "plugin" does not get evaluated,
but strings starting with "plugin." such as "plugin.version" DO get
evaluated. The eBook "Better Builds With Maven" indicates (in A.2.1) that
${plugin} should work. Is this a bug?

I'm trying to write a very simple mojo to display a message which will
include the version number of the plugin.
I use the following annotations to access the plugin:
/**
* Plugin descriptor.
* @parameter default-value="${plugin}"
* @required
* @readonly
*/
private PluginDescriptor plugin;
and I do get a PluginDescriptor, but I find that it is completely empty.
getLog().info("Plugin: " +
ReflectionToStringBuilder.reflectionToString(plugin,
ToStringStyle.MULTI_LINE_STYLE));
displays
[INFO] Plugin: [EMAIL PROTECTED]
groupId=<null>
artifactId=<null>
version=<null>
goalPrefix=<null>
source=<null>

classRealm=<null>
artifactMap=<null>
introducedDependencyArtifacts=<null>
name=<null>
description=<null>

Am I trying the wrong approach?
