Question: How do I use Maven to create executable jars with dependencies?

I want to package my project into an executable JAR for distribution.

How do I make the Maven project package all the dependency jars into my output JARS?

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>
Copy the code

And then use

mvn clean compile assembly:single
Copy the code

The compile target should be added before Assembly: Single: single, otherwise the code in your own project is not included.

Check out the comments for more details.

Typically, this goal is related to the automated construction phase. This ensures that the JAR is built when MVN install or deploy/publish is performed.

<plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <archive> <manifest> <mainClass>fully.qualified.MainClass</mainClass> </manifest> </archive> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> </configuration> <executions> <execution> <id>make-assembly</id> <! -- this is used for inheritance merges --> <phase>package</phase> <! -- bind to the packaging phase --> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>Copy the code

As a Java programmer, spring Boot is still a must!!

Purpose: Package the specified environment and package a JAR with dependencies.
