How do I get my project's runtime dependencies copied into the target/lib
folder?
As it is right now, after mvn clean install
the target
folder contains only my project's jar, but none of the runtime dependencies.
This question is related to
java
maven
dependencies
maven-2
maven-3
A simple and elegant solution for the case where one needs to copy the dependencies to a target directory without using any other phases of maven (I found this very useful when working with Vaadin).
Complete pom example:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>groupId</groupId>
<artifactId>artifactId</artifactId>
<version>1.0</version>
<dependencies>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.1.1</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<phase>process-sources</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${targetdirectory}</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Then run mvn process-sources
The jar file dependencies can be found in /target/dependency
You can use the the Shade Plugin to create an uber jar in which you can bundle all your 3rd party dependencies.
If you're having problems related to dependencies not appearing in the WEB-INF/lib file when running on a Tomcat server in Eclipse, take a look at this:
You simply had to add the Maven Dependencies in Project Properties > Deployment Assembly.
Just to spell out what has already been said in brief. I wanted to create an executable JAR file that included my dependencies along with my code. This worked for me:
(1) In the pom, under <build><plugins>, I included:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<archive>
<manifest>
<mainClass>dk.certifikat.oces2.some.package.MyMainClass</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
(2) Running mvn compile assembly:assembly produced the desired my-project-0.1-SNAPSHOT-jar-with-dependencies.jar in the project's target directory.
(3) I ran the JAR with java -jar my-project-0.1-SNAPSHOT-jar-with-dependencies.jar
This works for me:
<project>

<profile>
<id>qa</id>

<plugins>
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>

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

</build>

All you need is the following snippet inside pom.xml's build/plugins
:
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
The above will run in the package
phase when you run
mvn clean package
And the dependencies will be copied to the outputDirectory specified in the snippet, i.e. lib
in this case.
If you only want to do that occasionally, then no changes to pom.xml are required. Simply run the following:
mvn clean package dependency:copy-dependencies
To override the default location, which is ${project.build.directory}/dependencies
, add a System property named outputDirectory
, i.e.
-DoutputDirectory=${project.build.directory}/lib
You can use the the Shade Plugin to create an uber jar in which you can bundle all your 3rd party dependencies.
Try something like this:

<artifactId>maven-jar-plugin</artifactId>

<addClasspath>true</addClasspath>

<mainClass>MainClass</mainClass>

<configuration>
<outputDirectory>
${project.build.directory}/lib
</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
mvn install dependency:copy-dependencies
Works for me with dependencies directory created in target folder. Like it!
The best approach depends on what you want to do:
Take a look at the Maven dependency plugin, specifically, the dependency:copy-dependencies goal. Take a look at the example under the heading The dependency:copy-dependencies mojo. Set the outputDirectory configuration property to ${basedir}/target/lib (I believe, you'll have to test).
Hope this helps.

If you want to deliver a bundle of your application jar, together with all its dependencies and some scripts to invoke the MainClass, look at the appassembler-maven-plugin.
The following configuration will generate scripts for Window and Linux to launch the application (with a generated path referencing all the dependency jars, download all dependencies (into a lib folder below target/appassembler). The assembly plugin can then be used to package the whole appassembler directory to a zip which is installed/deployed along with the jar to the repository.

If you make your project a war or ear type maven will copy the dependencies.
If you're having problems related to dependencies not appearing in the WEB-INF/lib file when running on a Tomcat server in Eclipse, take a look at this:
You simply had to add the Maven Dependencies in Project Properties > Deployment Assembly.
If you want to do this on an occasional basis (and thus don't want to change your POM), try this command-line:
mvn dependency:copy-dependencies -DoutputDirectory=${project.build.directory}/lib
If you omit the last argument, the dependences are placed in target/dependencies
.

It's a heavy solution for embedding heavy dependencies, but Maven's Assembly Plugin does the trick for me.
@Rich Seller's answer should work, although for simpler cases you should only need this excerpt from the usage guide:
<project>
<build>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2.2</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
