Issue
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:
And my pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

The following error, which I get when I start the command:
$ mvn -Dmockserver.initializationClass="mockserver.ExampleInitializationClass" mockserver:run

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);
}
}
