Using maven-assembly-plugin with local dependencies

Question

    <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
            <archive>
                <manifest>
                    <mainClass>com.company.Main</mainClass>
                </manifest>
            </archive>
        </configuration>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>single</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

The problem is I have some local dependencies I'd like to keep in the project.

I defined them in pom.xml like so:

    <dependency>
        <groupId>groupid</groupId>
        <artifactId>local</artifactId>
        <version>1.1</version>
        <scope>system</scope>
        <systemPath>${basedir}/lib/local-utilities-1.1.jar</systemPath>
    </dependency>

Now when I package the whole thing maven-assembly-plugin packs only dependencies that are automatically downloaded and available in repo... That's probably because those local JARs are available in compile phase, not in package phase (correct?).

How can I make this plugin include those dependencies as well? I tried changing <scope> to package and other phases, but apparently that's not allowed by Maven.

Start using a repository manager or use [Stephen Collony's plugin](https://github.com/stephenc/non-maven-jar-maven-plugin) which is a better solution than `system scope`. — khmarbaise, Oct 21 '14 at 15:38

You need to "manually" copy those dependencies so that the packager can include them.

<build>
        <pluginManagement>      
            <plugins>
                <!-- Ignore/Execute plugin execution -->
