title: Why does openapi-generator not create a package.json with typescript-angular?
body: <p>I am generating code for <code>typescript-angular</code> with the openapi-generator-maven-plugin like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"&gt;
    &lt;build&gt;
      &lt;plugins&gt;
        &lt;plugin&gt;
          &lt;groupId&gt;org.openapitools&lt;/groupId&gt;
          &lt;artifactId&gt;openapi-generator-maven-plugin&lt;/artifactId&gt;
          &lt;version&gt;4.2.0&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;${project.basedir}/../my_server/openapi.json&lt;/inputSpec&gt;
                &lt;generatorName&gt;typescript-angular&lt;/generatorName&gt;
                &lt;output&gt;${project.basedir}&lt;/output&gt;
                &lt;npmName&gt;myClientRest&lt;/npmName&gt;
                &lt;npmRepository&gt;http://localhost:8444/repository/npm-releases/&lt;/npmRepository&gt;
                &lt;providedInRoot&gt;true&lt;/providedInRoot&gt;
                &lt;apiModulePrefix&gt;my&lt;/apiModulePrefix&gt;
                &lt;stringEnums&gt;true&lt;/stringEnums&gt;
              &lt;/configuration&gt;
            &lt;/execution&gt;
          &lt;/executions&gt;
        &lt;/plugin&gt;
      &lt;/plugins&gt;
    &lt;/build&gt;
  &lt;/project&gt;
  </code></pre>
  
  <p>What I am missing now is a <code>package.json</code> file so that I could do a <code>npm install</code>.
  From some older swagger examples it looks like with the swagger plugin a <code>package.json</code> file was generated.</p>
  
  <p>So my question is why is the <code>package.json</code> file not generated and what could I do to get one?</p>
  
  <p>The output of the generator run looks ok to me:</p>
