Pass maven properties to maven-antrun-plugin

Problem:

You want to bundle a your application jar files with other software artifacts but as maven names your jar file as magic-app-${project.version}.jar your maven-antrun-plugin fails to pick it up on its own.

Solution:
This was a persistent irritant as every time we upgraded our applications' version we needed to manually enter the same version name to build.properties and only then we can package latest jars for release.

After exploring certain unsatisfactory solution like;

• using-maven-to-output-the-version-number-to-a-text-file
• how-can-i-get-maven-to-write-a-property-into-a-property-file-at-package-time

Finally, got some hints from;

• maven-antrun-plugin examples 

Update your pom as shown below to export maven properties to ant build at run time.

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>1.7</version>
        <executions>
          <execution>
            <phase>package</phase>
            <configuration>
              <target>
                <property name="release.version" value="${project.version}" />                <ant antfile="build.xml" />
              </target>
            </configuration>
            <goals>
              <goal>run</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

 Hope that helps.

Running Java in debug mode using Apache Ant

Configure your Java task as given below;

<java classname="org.zero.Main" fork="true" failonerror="true">
            <sysproperty key="DEBUG" value="true" />
            <jvmarg value="-Xdebug" />
            <jvmarg value="-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8999" />
            <jvmarg value="-Xnoagent" />
            <jvmarg value="-Djava.compiler=none" />
            <arg value="${project.root}/conf/preferences.xml" />
            <classpath refid="project.classpath" />
        </java>

Further,  configure your eclipse debug remote application to listen to the specified port (8999 in this case).

Also, add Thread.sleep(1000); as the first line in your main method.

Execute Java task and try connecting from eclipse, you may need to increase the thread sleep time.
