title: Maven p16: Assembly, java-with-dependencies date: 2012-3-14 23:50:03 tags: maven,maven-assembly

The standard jar created will not include any dependencies included, as a quick way around this you can create a jar with dependencies. This is all the byte code included in the same jar, ergo it will be large.

In the build then plugins tag:

	<plugin>
		<artifactId>maven-assembly-plugin</artifactId>
		<configuration>
			<descriptorRefs>
				<descriptorRef>
					jar-with-dependencies
				</descriptorRef>
			</descriptorRefs>
		</configuration>			
	</plugin>

We're using the assembly plugin, and configuring it to create a description jar-with-dependencies.

This won't be created automatically. We'll have to run mvn install assembly:assembly to create a jar in target/itsname-jar-with-dependencies.jar

To ensure it is created automatically, change its configuration to tell it to run on execution by specifying a executions -> execution, with the phase and the configuration within that.

	<plugin>
		<artifactId>maven-assembly-plugin</artifactId>
		<executions>
			<execution>
				<id>itsname</id>
				<phase>package</phase>
				<goals>
					<goal>single</goal>
				</goals>
				<configuration>
					<descriptorRefs>
						<descriptorRef>
							jar-with-dependencies
						</descriptorRef>
					</descriptorRefs>
				</configuration>
			</execution>
		</executions>
	</plugin>
