Why does openapi-generator not create a package.json with typescript-angular?

Question

I am generating code for typescript-angular with the openapi-generator-maven-plugin like this:

<?xml version="1.0" encoding="UTF-8"?>
<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">
  <build>
    <plugins>
      <plugin>
        <groupId>org.openapitools</groupId>
        <artifactId>openapi-generator-maven-plugin</artifactId>
        <version>4.2.0</version>
        <executions>
          <execution>
            <goals>
              <goal>generate</goal>
            </goals>
            <configuration>
              <inputSpec>${project.basedir}/../my_server/openapi.json</inputSpec>
              <generatorName>typescript-angular</generatorName>
              <output>${project.basedir}</output>
              <npmName>myClientRest</npmName>
              <npmRepository>http://localhost:8444/repository/npm-releases/</npmRepository>
              <providedInRoot>true</providedInRoot>
              <apiModulePrefix>my</apiModulePrefix>
              <stringEnums>true</stringEnums>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

What I am missing now is a package.json file so that I could do a npm install. From some older swagger examples it looks like with the swagger plugin a package.json file was generated.

So my question is why is the package.json file not generated and what could I do to get one?

The output of the generator run looks ok to me:

Looks like the description of the plugin is not very clear (at least to me), because it seems that:

<configuration>
  <npmName>myClientRest</npmName>
</configuration>

is wrong and should be replaced with:

<configuration>
  <additionalProperties>npmName=myClientRest</additionalProperties>
</configuration>

or with:

<configuration>
  <configOptions>
    <npmName>tmsClientRest</npmName>
  </configOptions>
</configuration>

to make the generation of package.json and tsconfig.json work.

So my original example should be changed to:
