Maven Antrun Not Executing Tasks

Question

I'm using Maven AntRun plugin 1.6 and from their example I cannot code the following ant task to be executed.

Example url: http://maven.apache.org/plugins/maven-antrun-plugin/examples/classpaths.html

I just get the following message when I execute mvn antrun:run. No ant target defined - SKIPPED

What am I doing wrong?

Here's my POM:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
            <version>1.6</version>
            <executions>
                <execution>
                    <id>compile</id>
                    <phase>compile</phase>
                    <configuration>
                        <target>
                            <property name="compile_classpath" refid="maven.compile.classpath" />
                            <property name="runtime_classpath" refid="maven.runtime.classpath" />
                            <property name="test_classpath" refid="maven.test.classpath" />
                            <property name="plugin_classpath" refid="maven.plugin.classpath" />

                            <echo message="compile classpath: ${compile_classpath}" />
                            <echo message="runtime classpath: ${runtime_classpath}" />
                            <echo message="test classpath:    ${test_classpath}" />
                            <echo message="plugin classpath:  ${plugin_classpath}" />
                        </target>
                    </configuration>
                    <goals>
                        <goal>run</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

Answer 1

Since you have configured the maven antrun plugin in your pom.xml, you only need to call the lifecycle goal configured for the plugin. In this case

mvn compile

This will do the needful.

Answer 2

try this

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
            <version>1.7</version>
            <executions>
                <execution>
                    <id>default-cli</id>
                    <configuration>
                        <target>
                            <property name="compile_classpath" refid="maven.compile.classpath" />
                            <property name="runtime_classpath" refid="maven.runtime.classpath" />
                            <property name="test_classpath" refid="maven.test.classpath" />
                            <property name="plugin_classpath" refid="maven.plugin.classpath" />

                            <echo message="compile classpath: ${compile_classpath}" />
                            <echo message="runtime classpath: ${runtime_classpath}" />
                            <echo message="test classpath:    ${test_classpath}" />
                            <echo message="plugin classpath:  ${plugin_classpath}" />
                        </target>
                    </configuration>
                    <goals>
                        <goal>run</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

note the id

<id>default-cli</id>

and run the command

mvn antrun:run

reason for doing this way: if you don't actually want to "compile", running "mvn compile" to execute something else could be counter productive.
