Question

I’ve got a following problem:

I have configured a ant plugin within my pom.xml file for a verify phase. The task is simply to echo some string to console. The problem is that I see my execution being taken into accoutn, but no tasks get executed. Have anybody encountered similar problem? Below is the code of my pom.xml file:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<description>This is just to test pom inheritance</description>

The output I get when running mvn verify is as follows:

[INFO] Scanning for projects...
[INFO]
[INFO] ------------------------------------------------------------------------
[INFO] Building parentApp 0.0.1-SNAPSHOT

So there is eventually no output between Executing tasks and Executed tasks, but the plugin itself is taken to account. Any idea why?

Answer 1

Possibly the 1.1 version of the maven antrun plugin has bugs.

The following snippet works for me. Note that <mkdir>./hey</mkdir is incorrect syntax for ant mkdir task. Also, task is deprecated in favor of target.

   <plugin>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>1.7</version>
        <executions>
            <execution>
                <id>echodir</id>
                <goals>
                    <goal>run</goal>
                </goals>
                <phase>verify</phase>
                <inherited>true</inherited>
                <configuration>
                    <target>
                        <echo>*************************************************** Build Dir</echo>
                        <mkdir dir="hey"/>
                    </target>
                </configuration>
            </execution>
        </executions>
    </plugin>
