How to get artificactId of dependencies in Maven? - maven

Question

I have multi-module project. Dependencies are as follows:
<dependencies>
<dependency>
<groupId>com.gwr</groupId>
<artifactId>gwr-commons</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.gwr</groupId>
<artifactId>gwr-places-module</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.gwr</groupId>
<artifactId>gwr-devices-module</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.gwr</groupId>
<artifactId>gwr-events-module</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.gwr</groupId>
<artifactId>gwr-controls-module</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.gwr</groupId>
<artifactId>gwr-logs-module</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
And, under src/main/resources of each module/dependency I have one ZIP file named as <module>-persistence.zip (e.g. C:\gwr-logs-module\src\main\resources\logs-persistence.zip). I want to copy this ZIP file of each module under some other directory let us say C:\users\user\project. I have defined maven-resources-plugin as below:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-presubscriptionfiles</id>
<phase>validate</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${user.home}/${dasmo.storage}/</outputDirectory>
<overwrite>true</overwrite>
<resources>
<resource>
<directory>${basedir}/../gwr-logs-module/src/main/resources</directory>
<includes>
<include>*.zip</include>
</includes>
</resource>
<resource>
<directory>${basedir}/../gwr-devices-module/src/main/resources</directory>
<includes>
<include>*.zip</include>
</includes>
</resource>
<resource>
<directory>${basedir}/../gwr-controls-module/src/main/resources</directory>
<includes>
<include>*.zip</include>
</includes>
</resource>
<resource>
<directory>${basedir}/../gwr-events-module/src/main/resources</directory>
<includes>
<include>*.zip</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
As you see, under resource section I have to hard code each module name. How can I avoid this? Can't we use artifactId of each dependency? If yes, how to use it? Or is there any other way to do this job?
Thank you so much.

You can reduce the <plugin> section in your multi-module POM to the following:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-presubscriptionfiles</id>
<!-- Note: this phase is more appropriate than 'validate' -->
<phase>process-resources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${user.home}/${dasmo.storage}</outputDirectory>
<overwrite>true</overwrite>
<resources>
<resource>
<directory>${project.basedir}/src/main/resources</directory>
<!-- or likewise
<directory>${project.projectDirectory}/src/main/resources</directory>
-->
<includes>
<include>*.zip</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
If you declare your multi-module project as <parent> in any of your sub-module POMs this will be inherited by them (see Introduction to the POM, Project Inheritance) and such performed at each sub-module build.
Note: basedir is deprecated in favor of project.basedir.
See Maven: The Complete Reference, Multi-module vs. Inheritance for further reading.
