Disable the default-jar execution


I am using Maven Assembly plugin to pack a jar file.

But when I run mvn package, maven always trigger the [jar:jar {execution: default-jar}] to create a default jar file.

So I will have 2 jar files (one created by Assembly plugin and one created by Maven jar which i don't want to be created).

How can I turn off the default-jar execution?

In my pom.xml, I am using: <packaging>jar</packaging>.

I don't want to change it to <packaging>pom</packaging>.

  • (...) So i will have 2 jar files (one created by assembly plugin and one created by maven jar which i dont want to be created).

    Looks like you're doing pretty complicated things. Maybe Maven is not the right tool in your case.

    How can I turn off the execution: default-jar.

    You can set the <phase> of the corresponding execution to something unknown, like none:

      <plugin>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.3.1</version>
        <executions>
          <execution>
            <id>default-jar</id>
            <phase>none</phase>
          </execution>
        </executions>
      </plugin>
      <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.2</version>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
        <executions>
          <execution>
            <id>make-assembly</id>
            <!-- this is used for inheritance merges -->
            <phase>package</phase>
            <!-- append to the packaging phase. -->
            <goals>
              <goal>single</goal>
              <!-- goals == mojos -->
            </goals>
          </execution>
        </executions>
      </plugin>
    

    This seems to work as long as you're providing something else to be installed, like an assembly (I only tested install). But of course, this is a hack.
