How to Automatically Copy Dependencies to target/lib with Maven?

Automatically Copying Dependencies to target/lib with Maven

When running mvn clean install, the target folder usually only contains the project's JAR file, excluding runtime dependencies. To address this, the maven-dependency-plugin can be configured to copy these dependencies into the desired directory.

Solution:

Implement the following configuration within the project's POM.xml file:

<plugin>
  <artifactId>maven-dependency-plugin</artifactId>
  <executions>
    <execution>
      <phase>install</phase>
      <goals>
        <goal>copy-dependencies</goal>
      </goals>
      <configuration>
        <outputDirectory>${project.build.directory}/lib</outputDirectory>
      </configuration>
    </execution>
  </executions>
</plugin>

This configuration directs the copy-dependencies goal to run during the install phase. The outputDirectory parameter specifies the destination path for the copied dependencies, which in this case is the target/lib folder.

By adding this configuration, the mvn clean install command will now copy all runtime dependencies into the target/lib folder, ensuring their availability for deployment or further processing.
