Mockserver maven plugin: init mockserver expectations from file - maven-failsafe-plugin

Question

I'm using Mockserver maven plugin to mock some requests for integration tests.
My pom.xml looks like:
...
<plugin>
<groupId>org.mock-server</groupId>
<artifactId>mockserver-maven-plugin</artifactId>
<version>5.5.1</version>
<configuration>
<serverPort>1080</serverPort>
<logLevel>DEBUG</logLevel>
<initializationClass>com.mycompany.ExampleInitializationClass</initializationClass>
</configuration>
<executions>
<execution>
<id>run-mockserver</id>
<phase>pre-integration-test</phase>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>stop-mockserver</id>
<phase>post-integration-test</phase>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
...
Problem here is that I have to provide expectations using a class (com.mycompany.ExampleInitializationClass) and I want to provide expectations using a JSON file like described here:
http://www.mock-server.com/mock_server/initializing_expectations.html
I didn't find any way in the plugin configuration to initialize the Mockserver with the property:
-Dmockserver.initializationJsonPath
Is there any way to achieve that? Thanks in advance.

You just have to define initializationJson property specifying path to JSON file with expectations:
<plugin>
<groupId>org.mock-server</groupId>
<artifactId>mockserver-maven-plugin</artifactId>
<version>5.5.1</version>
<configuration>
<serverPort>1080</serverPort>
<logLevel>DEBUG</logLevel>
<initializationJson>expectations.json</initializationJson>
</configuration>
<executions>
...
</executions>
</plugin>
The catch here is that the file path is relative to testClasspath directory (e.g. ${project.basedir}/target/test-classes/), so you have to copy the expectation file there. You may use e.g. maven-antrun-plugin for this (as below) or
maven-resources-plugin.
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<copy file="your/expectations.json" todir="${project.basedir}/target/test-classes/"/>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
