Question

I am using maven assembly plugin. in my pom.xml, pakaging type: jar and i dont use maven jar plugin.

Whenever i run mvn clean package, it create 2 jar files: one is from maven assembly, another one is created by default (due to packaging type =jar). I want to keep only the jar file created by assembly plugin only. How to do that?

You may have your reasons but I doubt that it is a good solution to skip the default jar being built and deployed.

Anyhow here is how you can disable the default jar being built.

<build>
    <plugins>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.3</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <id>make-assembly</id>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <!-- some configuration of yours... -->
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.3.1</version>
            <executions>
                <execution>
                    <id>default-jar</id>
                    <!-- put the default-jar in the none phase to skip it from being created -->
                    <phase>none</phase>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
