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);
    }
}
