How to use Maven pom to download jar files only to a specific directory?

To download JAR files to a specific directory using Maven's pom.xml configuration, you can use the maven-dependency-plugin and specify the output directory where you want the downloaded JAR files to be stored. Here's how to do it:

  1. Open your project's pom.xml file.

  2. Inside the <build> section, add the maven-dependency-plugin configuration with a <outputDirectory> element specifying the target directory for the downloaded JAR files. For example:

    <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>3.2.0</version> <!-- Use the latest version --> <executions> <execution> <id>copy-dependencies</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <!-- Define the output directory where JAR files will be stored --> <outputDirectory>${project.build.directory}/custom-lib</outputDirectory> </configuration> </execution> </executions> </plugin> </plugins> </build>

    In the above configuration:

    • We use the maven-dependency-plugin and specify the copy-dependencies goal.
    • We set the <outputDirectory> to ${project.build.directory}/custom-lib, which will store the downloaded JAR files in the custom-lib directory within the target directory of your project.

  3. Save the pom.xml file.

  4. Run the following Maven command to download the JAR files and place them in the specified directory:

    mvn package

    After running the command, the JAR files and their transitive dependencies will be downloaded from your project's dependencies and stored in the target/custom-lib directory.

By configuring the maven-dependency-plugin as shown above, you can control the location where the downloaded JAR files are stored during the Maven build process.
