Maven Dependency Selection

I am facing a problem with a web-application that i have.

The web-app uses jersey library and specificaly version 1.8.

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.8</version>
    </dependency>

The problem is that an upstream dependency depends on another Jersey version 2.3 which looks like this:

    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-server</artifactId>
        <version>2.3</version>
    </dependency>

This causes me problems as initially Jersey 1.8 is loaded, but then when methods are invoked it seems that are called in Jersey-server 2.3

I would like to know is there anything i can do to exclude the jersey-server that i don't want?

To exclude a transitive dependency:

<project>
...
<dependencies>

 <dependency>
  <groupId>groupid.of.what.needs.jersey</groupId>
  <artifactId>artifactId.of.what.needs.jersey</artifactId>
  <version>1.0</version>
  <exclusions>
    <exclusion>  <!-- declare the exclusion here -->
      <groupId>org.glassfish.jersey.core</groupId>
      <artifactId>jersey-server</artifactId>
      <version>2.3</version>
    </exclusion>
  </exclusions>

</dependency>

But, there's a danger that the other dependency might not be compatible with Jersey 1.8. It would be best to use the same version yourself, if possible.

You can exclude dependencies with this kind of declaration in your dependencies section

<dependency>
  <groupId>your.upstream.dependency.groupid</groupId>
  <artifactId>your.upstream.dependency.artifactid</artifactId>
  <version>[upstream.dep.version]</version>
  <exclusions>
    <exclusion>  <!-- declare the exclusion here -->
      <groupId>org.glassfish.jersey.core</groupId>
      <artifactId>jersey-server</artifactId>
    </exclusion>
  </exclusions> 
</dependency>

reference

Be careful that it may have a very bad impact, especially because you are excluding something that seems newer (i.e version 2.3, but with a different groupid)
