Maven Include Dependencies in JAR Artifact

Internal

• Maven jar Plugin
• Maven dependency Plugin

Overview

There are situations when we want to extract some of the dependencies and bundle them with the JAR artifact, merged with the artifact classes. This is done using the jar plugin and the dependency plugin together, as described below.

Configure the Maven dependency plugin to unpack dependencies, or just some of them, in the directory that will be archived by the jar plugin:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>3.0.0</version>
    <executions>
        <execution>
            <id>unpack-some-dependencies</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>unpack-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/classes</outputDirectory>
                <includes>**/SimpleStateless.class</includes>
                <overWriteReleases>false</overWriteReleases>
                <overWriteSnapshots>false</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
             </configuration>
         </execution>
    </executions>
</plugin>
