How do I repair a cxf-codegen-plugin throwing an error in POM

Question

I want to use cxf-codegen-plugin to generate-sources with wsdl2java in my camel maven project.

I added the plugin as follows to my pom.

<plugin>
   <groupId>org.apache.cxf</groupId>
   <artifactId>cxf-codegen-plugin</artifactId>
   <version>3.2.4</version>
   <executions>
     <execution>
       <id>generate-sources</id>
       <phase>generate-sources</phase>
       <configuration>
         <wsdlOptions>
           <wsdlOption>
             <wsdl>src/main/resources/wsdl/BookService.wsdl</wsdl>
           </wsdlOption>
         </wsdlOptions>
       </configuration>
       <goals>
         <goal>wsdl2java</goal>
       </goals>
     </execution>
   </executions>
 </plugin>

This throws an error in the pom...

Execution generate-sources of goal org.apache.cxf:cxf-codegen-plugin:3.2.4:wsdl2java failed: A required class was missing while executing org.apache.cxf:cxf-codegen-
 plugin:3.2.4:wsdl2java: javax/xml/bind/annotation/adapters/HexBinaryAdapter ----------------------------------------------------- realm = plugin>org.apache.cxf:cxf-codegen-

I tried other example projects like https://github.com/sigreen/camel-cxf-soap-client and got similar errors in the pom Since I am sure it worked back in 2015 when this project was committed, I assume it is a version mismatch today.

If someone has a recent project with cxf-codegen-plugin that would help.

Answer 1

I kept making changes based on details in the error stacks that kept changing with each change. Here is the final plugin entry in the pom that was clean...

<plugin>

            </plugin>

Answer 2

I changed my jdk version from 11 to 8 and it works for me

Answer 3

for the following configuration:

<plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>11</source>
                    <target>11</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.cxf</groupId>
                <artifactId>cxf-codegen-plugin</artifactId>
                <version>3.5.2</version>
                <executions>
                    <execution>
                        <id>generate-sources</id>
                        <phase>generate-sources</phase>
                        <configuration>
                            <!-- <sourceRoot>${project.build.sourceDirectory}/generated-sources/cxf</sourceRoot>-->
                            <wsdlOptions>
                                <wsdlOption>
                                    <wsdl>src/main/resources/9874.wsdl
                                    </wsdl>
                                </wsdlOption>
                            </wsdlOptions>
                        </configuration>
                        <goals>
                            <goal>wsdl2java</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

I used this dependency and it worked well:

        <dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-cxf</artifactId>
            <version>3.17.0</version>
            <scope>provided</scope>
        </dependency>
