Eliminating recursive Maven dependency

Let's say I'm developing project A that depends on projects B and JUnit-11.

A -> junit-11 and B

      

        
        
        
      

    

Project B depends on projects C and JUnit-8. but it is already packaged and I have no control over its contents.

B -> junit-8  and C

      

        
        
        
      

    

The C project also depends on jUnit-8.

C -> junit-8

      

        
        
        
      

    

Now the problem is when I try to build my project (project A) it also gets jUnit-8 which breaks the compilation. I can exclude project B's dependency on jUnit-8 when defining this in my pom.xml, but that does not apply to project C's dependency. As a result, jUnit-8 is still loading and breaking my project.

here is the associated pom.xml:

Project A (My Project) :pom.xml:
<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.11</version>
    </dependency>

    <dependency>
        <groupId>B</groupId>
        <artifactId>B</artifactId>
        <version>1.0</version>
        <exclusion>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>       
        </exclusion>

    </dependency>
</dependencies>

Project B (Existing project):pom.xml:
<dependencies>
       <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.8</version>
        </dependency>
       <dependency>
            <groupId>C</groupId>
            <artifactId>C</artifactId>
            <version>1.0</version>
        </dependency>
</dependencies>

Project C (Existing project):pom.xml:
<dependencies>
       <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.8</version>
        </dependency>
</dependencies>

      

        
        
        
      

    

Any advice on how to define a recursive exception excluding jUnit-8 across all sub-dependencies?
