Expectation Initializers with mockserver java not load


I use mockserver (mock-server) on my java project and now I want to start it with a persistent Expectation Initializers with the mvn command. I tested it with a json file and it work correctly, but when I use or rather start it with an Expectation Initializers (Java file) the configuration is not load on startup from the mock-server, because the file was not found.
The command used is:

mvn -Dmockserver.initializationClass="mockserver.ExpectationInitializer" mockserver:run

The structure of my example project is: enter image description here

And my pom.xml:

The following error, which I get when I start the command:

Thank you for your help :)


Solution

  • Your code is in the test package. In my case, I'm using these dependencies.

        <dependency>
          <groupId>org.mock-server</groupId>
          <artifactId>mockserver-netty</artifactId>
          <version>${mock-sever-netty-version}</version>
        </dependency>
        <dependency>
          <groupId>org.mock-server</groupId>
          <artifactId>mockserver-client-java</artifactId>
          <version>${mock-sever-netty-version}</version>
        </dependency>
    

    with this properties

      <properties>
        <mock-sever-netty-version>5.13.2</mock-sever-netty-version>
        <apche-http-version>4.4.1</apche-http-version>
      </properties>
    

    Then I have a principal class that sets the initializer class

    public class Application {
    
        public static void main(String[] args) {
            System.setProperty("mockserver.initializationClass",
                ExpectationInitializerMock.class.getName());
            ClientAndServer mockServer = startClientAndServer(1080);
        }
    }
