Bill,
I've sent the anttask code to your mail adress .
Your mojo configuration looks ok (by eyeball inspection).
The default expression of each parameter is ${name}.
defaultValue will be used when expression evaluates to null.
So as long as you don't configure ${name} on the mvn command line or in
the plugin configuration, defaultValue is used.
The parameter is marked readonly and required so I prefer to use
expression to set is value.
I don't want users to override this value to make the build reproduceable.

Martin,
Thanks a lot.
It will very appreciated if you can send your anttask me.
btw, you said, I need to define a path as a readonly parameter
of type java.util.List and set expression to ${maven.project.classpath},
is it "expression" tag, or "defaultValue" tag.
I guess the mojo should me like this,
<mojo>
<goal>get-classpath</goal>
<call>get-classpath</call>
<description>get classpath</description>
<parameters>
<parameter>
<name>dependencyclasspath</name>
<property>dependencyclasspath</property>
<required>true</required>
<readonly>true</readonly>
<defaultValue>${maven.project.classpath}</defaultValue>
<type>java.util.List</type>
<description>maven dependency
classpath.</description>
</parameter>
</parameters>
</mojo>
is that right?
Regards,
Bill

Bill,
See http://www.nabble.com/forum/ViewPost.jtp?post=2661163&framed=y.
The classpaths are not available to the ant project by default. You need
to define a path as a readonly parameter of type java.util.List and set
expression to e.g ${maven.project.testClasspath}.
Since the parameter is not a String, it is added to the projects as a
reference, with key name equal to the parameter name.
Then, you need an anttask to convert the list into a path.
I've the anttask code available, also sent it to John Casey but got no
reply yet. I can give you the code in case you are interested.

Hello,
Thanks to the guide,
http://maven.apache.org/guides/plugin/guide-ant-plugin-development.html
I have successfully developed some simple ant plugin. but when I run an ant
script to refer the maven classpath, I got
[ERROR] BUILD ERROR
[INFO]
---------------------------------------------------------------------------
-
[INFO] Failed to execute: Executing Ant script: /test.build.xml
[get-classpath]: Failed to execute.
Reference maven.dependency.classpath not found..
even I tried use a parameter with
<defaultValue>${project.runtimeClasspathElements}</defaultValue>
<type>java.util.Set</type>
I am using maven 2.0.2, Here is the source:
test.build.xml
<project>
<target name="get-classpath">
<echo>Try to get the classpath</echo>
<property name="out" refid="maven.dependency.classpath" />
<echo>out: ${out}</echo>
</target>
</project>
test.mojo.xml
<mojo>
<goal>get-classpath</goal>
<call>get-classpath</call>
<description>get classpath</description>
</mojo>
in the plugin pom.xml, do have following configuration:
<artifactId>maven-plugin-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-plugin-tools-ant</artifactId>
<version>2.0.1</version>
</dependency>
</dependencies>
btw, from the link
http://www.nabble.com/Support-for-mojos-written-in-Ant-t863193.html#a234229

seems we don't need to manually add any "maven.dependency.classpath" refids
to ANT,
that already happens behind the scenes. But why can't my ant script get
that reference?
Thanks in advance.
Bill
