Intellij Java 2016 & Maven : how to embed dependencies in JAR?

How can I create an executable JAR with dependencies using Maven? 33 answers

I finally managed to generate this JAR with Intellij Java, here is how I do:

add the dependencies in the pom.xml file

go to File -> Project Structure -> Artifacts -> New -> JAR -> From module with dependencies

choose the Main class and click OK

in your project, in src/main, create the "resources" folder

move the "META-INF" (with MANIFEST.MF in it) folder in this "resources" folder

go to Build -> build artifacts to build the JAR

EDIT

A better (and easier way) to do it is adding the following lines in the pom.xml file :

<build>
    <plugins>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>your.MainClass</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
            <executions>
                <execution>
                    <id>make-assembly</id>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

then use the "clean" and "package" maven commands.

The last 3 steps above (about MANIFEST.MF) still seem to be mandatory.

Okay, so you basically want to create a "fat jar" (sometimes called assembly), that contains all its own dependencies (usually, the dependencies are external).

You need to use a Maven plugin for that. Below is a sample assembly plugin configuration jar-with-dependencies:

<project>
  ...
  <build>
    ...
    <plugins>
      <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.6</version>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
        ...
</project>

then, simply run

mvn package
