How do you exclude a specific JAR file in Maven?

In Maven, you can use the tag to exclude files from a specific jar package.

Assuming we have a dependency as follows:

<dependency>
    <groupId>org.example</groupId>
    <artifactId>example-artifact</artifactId>
    <version>1.0.0</version>
</dependency>

If we want to exclude a specific JAR file from a dependency, we can add an tag to the dependency and specify the groupId, artifactId, and version number of the file we want to exclude. For example:

<dependency>
    <groupId>org.example</groupId>
    <artifactId>example-artifact</artifactId>
    <version>1.0.0</version>
    <exclusions>
        <exclusion>
            <groupId>com.example</groupId>
            <artifactId>example-library</artifactId>
        </exclusion>
    </exclusions>
</dependency>

The configuration above will exclude the file of the example-library jar package in the example-artifact dependency.

Be mindful that excluding a file from a particular JAR package may cause the dependencies to not work properly, so it is important to understand the impact on the project before excluding it.
