Trying to get maven antrun plugin to work

Question

Trying to get antrun plugin to work:

To get this to work I have assumed I need to included two entries in pom.xml:

the dependency:

    <dependency>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-antrun-plugin</artifactId>
      <version>1.7</version>
    </dependency>

and the plugin:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>1.7</version>
        <executions>
            <execution>
                <phase>package</phase>
                <configuration>
                    <target name="usage">
                        <echo message="This is how this target is used!"/>
                    </target>
                </configuration>
                <goals>
                    <goal>run</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

I don't know what phase to specify (I only want a standalone process to push my artifact to a remote server - that is the purpose of the antrun plugin, AFAIK, anyway. My intention is to use these ant targets as a way to ease in to migrating my entire build from Ant to Maven). Does my antrun target/s have to be run as part of a phase?

When I try to run this('org.apache.maven.plugins:maven-antrun-plugin:antrun:1.7:package') from STS(debug on), I get the following output:

The above-mentioned 'PluginResolutionException' wiki page gives some advice but I'm none the wiser. (I can see the plugin directory and files in my local m2 repository, so if it can't download it from the central maven repository, why is it not looking in my local repo?)

When I look in '~/.m2/repository/org/apache/maven/plugins/maven-antrun-plugin/1.7', I see these files:

m2e-lastUpdated.properties
maven-antrun-plugin-1.7.jar.sha1
maven-antrun-plugin-1.7.pom.sha1
maven-antrun-plugin-1.7.jar
maven-antrun-plugin-1.7.pom
_maven.repositories

... so surely this means I have the jar dependency and pom file requirement satisfied.

Should I be configuring a proxy? If so, why? What is the purpose of proxy configuration?

Ah. I got it to work. The following dependencies I had declared in pom.xml but outside of the plugin: <dependency> <groupId>ant</groupId> <artifactId>ant-optional</artifactId> <version>1.5.3-1</version> </dependency> <dependency> <groupId>org.apache.ant</groupId> <artifactId>com.springsource.org.apache.tools.ant</artifactId> <version>1.8.3</version> </dependency> <dependency> <groupId>com.jcraft</groupId> <artifactId>jsch</artifactId> <version>0.1.50</version> </dependency> I moved these into the scope of the antrun plugin element. That did the trick. — Jim

For me it worked adding the antrun maven dependencies like this:

<dependency> 
<groupId>ant</groupId> 
<artifactId>ant-optional</artifactId> 
<version>1.5.3-1</version> 
</dependency> 
<dependency>
    <groupId>org.apache.ant</groupId>
    <artifactId>ant</artifactId>
    <version>1.9.2</version>
</dependency>
<dependency>
    <groupId>org.apache.ant</groupId>
    <artifactId>ant-launcher</artifactId>
    <version>1.9.2</version>
</dependency>

<dependency>
 <groupId>com.jcraft</groupId> 
 <artifactId>jsch</artifactId> 
 <version>0.1.50</version> 
 </dependency>

Thanks for posting your fix Jim!!!
