CXF codegen maven plugin doesn't work OpenJDK 11

Question

I have been working with JDK 9 & 10 and CXF codegen plugin 3.2.5 and 3.2.6 with no problems but, today I'm trying to update my codebase from Oracle JDK 10 to OpenJDK 11 build 28, but I'm always getting the same error:

this is my pom.xml that use CXF codegen plugin:

<plugin>

Am I missing something? As far as I know this should work the same way that in JDK 9 and 10. There is an issue https://issues.apache.org/jira/browse/CXF-7741 that talk about JDK 11 compatibility, but again this is for CXF framework not for the plugin (I think).

This issue will be resolved in cxf 3.3.0 (https://issues.apache.org/jira/browse/CXF-7852)

For now, you can run mvn install in the mvn-plugins directory of https://github.com/apache/cxf to build the plugins, and set version in pom to 3.3.0-SNAPSHOT

Edit: Plugin is in the apache snapshots repo, so probably better to get it from there:

<pluginRepositories>         
   <pluginRepository>
      <id>apache.snapshots</id>
      <name>Maven Plugin Snapshots</name>
      <url>http://repository.apache.org/snapshots/</url>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
    </pluginRepository>
</pluginRepositories>
<build>
  <plugins>
    <plugin>
      <groupId>org.apache.cxf</groupId>
      <artifactId>cxf-codegen-plugin</artifactId>
      <version>3.3.0-SNAPSHOT</version>
...

Note (2019-01-28): The plugin is now released, we can add the dependency as usual:

<dependency>
  <groupId>org.apache.cxf</groupId>
  <artifactId>cxf-codegen-plugin</artifactId>
  <version>3.3.0</version>
  <type>maven-plugin</type>
</dependency>
