You can specify attributes in the <target/> configuration to execute or not Ant tasks depending some conditions. For example, to skip Ant call, you could add the following:
<project> ... <build> <plugins> ... <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-antrun-plugin</artifactId> <version>1.8</version> <executions> <execution> <phase> <!-- a lifecycle phase --> </phase> <configuration> <target unless="maven.test.skip"> <echo message="To skip me, just call mvn -Dmaven.test.skip=true"/> </target> </configuration> <goals> <goal>run</goal> </goals> </execution> </executions> </plugin> ... </plugins> </build> ... </project>
