Answer 1

I am able to reproduce your error. This has nothing to do with Jersey; it's an error you're making with Maven. mvn clean exec:java says: "delete all the .class files and then try to run the Main .class file". Since you deleted it, Maven can't find it. Here's a solution:

mvn clean compile exec:java

This should fix the problem in your question. This says "delete all the .class files, recompile them from source and then try to run the Main .class file"

To get past the next error you'll see, delete the test line from the client dependency in the pom.xml:

    org.glassfish.jersey.core
    jersey-client
    test

To:

    org.glassfish.jersey.core
    jersey-client
