Can you explain what is meant by a transitive dependency in the context of package management or project dependencies?

A transitive dependency is a dependency that comes into a project not directly, but through another dependency.

For example, if your project depends on library A, and library A in turn depends on library B, then library B is a transitive dependency for your project.

Managing transitive dependencies is important to avoid version conflicts and redundant libraries. In build systems like Maven or Gradle, transitive dependencies are automatically pulled in, but their versions can be overridden or excluded.

Example in Maven:

<dependency>
    <groupId>org.example</groupId>
    <artifactId>libraryA</artifactId>
    <version>1.0</version>
    <exclusions>
        <exclusion>
            <groupId>org.example</groupId>
            <artifactId>libraryB</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Here, we exclude the transitive dependency libraryB to control its version or remove it altogether.
