How can you use a dependency from the plugin's dependency scope in the maven-antrun-plugin? - maven

Question

We have a profile that uses maven-antrun-plugin to run a downloaded JAR.
Exhibit A: (this works)
We can reference the downloaded JAR using the property ${maven.dependency.com.foobar.target-jar.jar.path} (Can I use the path to a Maven dependency as a property?). But in this solution, the custom dependency and repository information isn't limited to just the scope of the profile.
<project>
...
<repositories>
<repository>
<id>thirdparty</id>
<name>Third Party</name>
<url>
[URL for the repository that holds the target JAR]
</url>
<layout>default</layout>
</repository>
</repositories>
...
<dependencies>
<dependency>
<groupId>com.foobar</groupId>
<artifactId>target-jar</artifactId>
<version>1.0.0</version>
</dependency>
</dependencies>
...
<profiles>
<profile>
<id>runJARprofile</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<inherited>false</inherited>
<executions>
<execution>
<id>run-jar</id>
<phase>package</phase>
<configuration>
<target name="runJar" fork="true">
<java jar="${maven.dependency.com.foobar.target-jar.jar.path}" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
...
</project>
Exhibit B: (haven't gotten it working)
Here, we moved the dependency and repository information into the profile. Maven downloads the artifact successfully, but we no longer know how to reference it by property.
<project>
...
<profiles>
<profile>
<pluginRepositories>
<repository>
<id>thirdparty</id>
<name>Third Party</name>
<url>
[URL for the repository that holds the target JAR]
</url>
<layout>default</layout>
</repository>
</pluginRepositories>
...
<id>runJARprofile</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<inherited>false</inherited>
<dependencies>
<dependency>
<groupId>com.foobar</groupId>
<artifactId>target-jar</artifactId>
<version>1.0.0</version>
</dependency>
</dependencies>
<executions>
<execution>
<id>run-jar</id>
<phase>package</phase>
<configuration>
<target name="runJar" fork="true">
<java jar="${?????}" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
...
</project>

Answer 1

I crated a POM similar to your Exhibit B here and got the following message during a mvn package -P runJARprofile:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.8:run
(run-jar) on project so-36848518: An Ant BuildException has occured:
Cannot execute a jar in non-forked mode. Please set fork='true'.
[ERROR] around Ant part ...<java jar="${my:test:jar}"/>...
I changed the respective line to:
<java jar="${my:test:jar} fork="true"/>
and:
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
