Maven Failed to initialize ear modules: Unknown artifact type[zip] for release-documentation

Question

Environment:

• Java 11
• Maven 3.6.3

I added the following dependency on submodule pom.xml EJB and the problem came up

    <dependency>
        <groupId>com.sun.xml.ws</groupId>
        <artifactId>jaxws-ri</artifactId>
        <version>2.3.3</version>
        <type>pom</type>
    </dependency>

I have no issues with the following commands:

mvn dependency:resolve
mvn dependency:tree

No clue how to find out what is happening...

Try excluding the documentation. You may also have to exclude samples.

       <dependency>
          <groupId>com.sun.xml.ws</groupId>
          <artifactId>jaxws-ri</artifactId>
          <version>2.3.3</version>
          <type>pom</type>
          <exclusions>
            <exclusion>
                <groupId>com.sun.xml.ws</groupId>
                <artifactId>release-documentation</artifactId>
            </exclusion>
            <exclusion>
