are there any examples of how to use maven-jar-plugin?

Question

I am very new to Maven and would like to see an example of how one uses the maven jar plugin. I already visited here but did not find any examples. On the documentation page, there were some parameters listed for this goal but what I was looking for is how one places them in the 'goal' or 'executions' tag. Thanks.

You usually don't use the jar plugin. If you set the packaging to jar, the goal jar:jar gets executed automatically.

If you want to configure the jar plugin, do it like this:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
        <excludes>
            <exclude>**/*.xml</exclude>
        </excludes>
    </configuration>
</plugin>

(Example: exclude all xml files from the jar)

There is no need to add any goal or execution blocks, a global configuration block is valid for all executions.

Reference:

• jar:jar goal
• Built-in lifecycle bindings
