Configuring Generation of Plugin Descriptor
To configure the generation of the plugin descriptor, add the following to the project's POM:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-plugin-plugin</artifactId>
<version>3.15.1</version>
<configuration>
<goalPrefix>plugin</goalPrefix>
<outputDirectory>target/dir</outputDirectory>
</configuration>
</plugin>
</plugins>
...
</build>
...
</project>
The goalPrefix parameter will set the goal prefix for the plugin that is specified in the descriptor. The outputDirectory parameter, on the other hand, specifies the target ___location of the generated plugin descriptor.
Example
For instance, if we make reference on MyMojo from maven-my-plugin which is generated by the Maven Archetype Plugin, i.e.:
mvn archetype:create \ -DgroupId=org.apache.maven.plugin.my \ -DartifactId=maven-my-plugin \ -DarchetypeArtifactId=maven-archetype-mojo
The plugin descriptor generated by mvn package should be:
<plugin>
<description></description>
<groupId>org.apache.maven.plugin.my</groupId>
<artifactId>maven-my-plugin</artifactId>
<version>1.0-SNAPSHOT</version>
<goalPrefix>my</goalPrefix>
<isolatedRealm>false</isolatedRealm>
<inheritedByDefault>true</inheritedByDefault>
<mojos>
<mojo>
<goal>touch</goal>
<description>Goal which touches a timestamp file.</description>
<requiresDirectInvocation>false</requiresDirectInvocation>
<requiresProject>true</requiresProject>
<requiresReports>false</requiresReports>
<aggregator>false</aggregator>
<requiresOnline>false</requiresOnline>
<inheritedByDefault>true</inheritedByDefault>
<phase>process-sources</phase>
<implementation>org.apache.maven.plugin.my.MyMojo</implementation>
