title: Generate code for multiple swaggers in the same project
body: <p>How do i generate code for multiple swagger files from within the same module/project in one pom.xml.</p>
  
  <p>In my application client had provided a swagger and we have one of the backend API to be called for which they provided swagger. I want to generate code for both of these in the same project. One way i was thinking is create separate module and execute the plugin separately and have those dependencies called out in main module.</p>
  
  <p>How do i generate code from one build plugin? Please point me to existing one if it is a repost. I couldn't find any.</p>
  
  <p>Here is the plugin i configured in pom.xml</p>
  
  <pre><code> &lt;plugin&gt;
              &lt;groupId&gt;io.swagger&lt;/groupId&gt;
              &lt;artifactId&gt;swagger-codegen-maven-plugin&lt;/artifactId&gt;
              &lt;version&gt;2.2.1&lt;/version&gt;
              &lt;executions&gt;
                  &lt;execution&gt;
                      &lt;goals&gt;
                          &lt;goal&gt;generate&lt;/goal&gt;
                      &lt;/goals&gt;
                      &lt;configuration&gt;
                        &lt;inputSpec&gt;${project.basedir}/src/main/ resources/Service.json&lt;/inputSpec&gt;&lt;inputSpec&gt;${project.basedir}/src /main/resources/Client.json&lt;/inputSpec&gt;
                          &lt;language&gt;java&lt;/language&gt;
                          &lt;configOptions&gt;
                              &lt;dateLibrary&gt;java8&lt;/dateLibrary&gt;
                          &lt;/configOptions&gt;
                          &lt;modelPackage&gt;com.service.model&lt;/modelPackage&gt;
                          &lt;environmentVariables&gt;
                              &lt;models/&gt;
                              &lt;supportingFiles&gt;false&lt;/supportingFiles&gt;
                          &lt;/environmentVariables&gt;
                      &lt;/configuration&gt;
                  &lt;/execution&gt;
              &lt;/executions&gt;
          &lt;/plugin&gt;
  </code></pre>
  
  <p>Also tried *.json. At anytime it is taking only one json file and generating the code.</p>
