the plugin so that it only converts the contracts and generates the stubs. To achieve

that, you need to configure Spring Cloud Contract Verifier plugin in exactly the same way
|

as you would for a provider. You need to copy contracts stored in
|
||||
<code class="literal">src/test/resources/contracts</code> and generate WireMock JSON stubs using the
|
||||
<code class="literal">mvn generateStubs</code> command. By default, the generated WireMock mapping is stored in a
|

directory named <code class="literal">target/mappings</code>. From these generated mappings, your project should

create additional artifacts with a classifier of <code class="literal">stubs</code> for easy deployment to the maven

repository.</p><p>Here is a sample configuration:</p><pre class="programlisting"><span xmlns:d="http://docbook.org/ns/docbook" class="hl-tag"><plugin></span>
