如果我在依赖树中看不到该库，如何从Maven中排除它？

<dependencies>
    <dependency>
        <groupId>com.example</groupId>
        <artifactId>my-project</artifactId>
        <version>1.0.0</version>
        <exclusions>
            <exclusion>
                <groupId>com.unwanted</groupId>
                <artifactId>unwanted-library</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
</dependencies>
