--------------------------------------------------------------

This could be categorized as a critical bug, considering that most of the mojo plugins available do not use the latest version of tools. So if someone needs to use the latest version of a tool, antrun is the only option which becomes restricted to ant's inbuilt tasks without this fix. However I was able to make the following work:

<path id="maven-ant-tasks.classpath"					path="${settings.localRepository}/org/apache/maven/maven-artifact-ant/${maven-artifact-ant.version}/maven-ant-tasks-${maven-artifact-ant.version}.jar"/>
<typedef  resource="org/apache/maven/artifact/ant/antlib.xml"
									classpathref="maven-ant-tasks.classpath" />

That is I was able to call "pom", "install" and "deploy" tasks.
maven-artifact-antlib was added as a dependency of the antrun plugin

>             Project: Maven 2.x Antrun Plugin
>          Issue Type: Bug
>    Affects Versions: 1.1
>            Reporter: ttest

> I'm trying to run an ant task during a Maven run. The classes for that Ant task are included in my Maven runtime dependencies(maven.runtime.classpath).
> Here the relevant snippet from my POM:
> <tasks>
> 	<path id="my.maven.runtime.classpath">
> 		<path refid="maven.runtime.classpath"/>
> 	</path>
> 	
> 	<taskdef name="mostGenerator" classname="com.bmw.most.generator.AntTask" classpathref="maven.runtime.classpath"/>
> 	
> 	<mostGenerator configurationFile="mostGenerator.configuration" targetDirectory="target/generated-sources/most"/>
> </tasks>
> This works if I don't provide depedencies in the POM for my plugin. But if I do provide depedencies it doesn't work. I consider this to be a bug since that should have no effect on the behaviour of "maven.runtime.classpath". My first guess is that this is a classloading issue. Probably by providing dependencies the classloaders get messed up and that causes the taskdef to not load the classes from maven.runtime.classpath because echoing the value of maven.runtime.classpath still gives the right classpath.
> I have tried all variants of dereferencing maven.runtime.classpath. Didn't work.
> Also which is very interesting if I hardcode the classpath in the taskdef to absolute pathnames it also does not work.
