Maven calling Ant

Question

I have a Maven project, I want Maven to "call" some target of ant, I’ve seen that there is a plugin "Maven-antrun-plugin" there on the apache site, but I can’t understand any example, someone could give me a simple example, like creating a . jar(I know you can do this in Maven)just to know more or less how it works.

Using the maven-antrun-plugin you can use a file ant external.

As an example, let’s consider this build.xml containing a target for

<?xml version="1.0"?>
<project name="stack-test">
    <target name="showJavaVersion">
        <exec executable="java">
            <arg value="-version" />
        </exec>
    </target>
</project>

And refer to it in the build of our pom.xml as follows:

<plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <executions>
        <execution>
            <id>compile</id>
            <phase>compile</phase>
            <configuration>
                <target>
                    <ant antfile="${basedir}/build.xml">
                        <target name="showJavaVersion" />
                    </ant>
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>

While executing the life Cycle Compile(mvn compile) we’ll have a similar exit:

Using directly on pom.xml, regardless of the build.xml, the equivalent configuration would be this:

<plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <executions>
        <execution>
            <id>compile</id>
            <phase>compile</phase>
            <configuration>
                <target name="showJavaVersion">
                    <exec executable="java">
                        <arg value="-version" />
                    </exec>
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>
