cxf-codegen-plugin and jaxb-maven-plugin for Java 21 and higher

Question

I am upgrading Java from 1.8 to 21 and spring boot from 2.5 to 3.2.2 for one of my applications ..

I get this error  

    Failed to execute goal org.apache.cxf:cxf-codegen-plugin:3.1.10:wsdl2java (generate-sources) on project :
Execution generate-sources of goal org.apache.cxf:cxf-codegen-plugin:3.1.10:wsdl2java failed: 
    A required class was missing while executing org.apache.cxf:cxf-codegen-plugin:3.1.10:wsdl2java: 

what is the right way to upgrade these plugins , I read a lot of articles online and each one suggets something and when I try those I get some other errors and its also confusing .. could someone kindly point out the right way to replace the cxf-codegen-plugin and jaxb-maven-plugin for Java 21 and higher ..

Here is my POM file

Answer 1

If you are targeting SpringBoot 3, you must know that this major version change includes moving from javax to jakarta based package.

I guess taking the following versions of the two plugins should do the job for you :

• org.apache.cxf:cxf-codegen-plugin : 4.0.3 (jaxb3 - jakarta based)
• org.jvnet.jaxb:jaxb-maven-plugin : 4.0.0 (jaxb4 - jakarta based, jdk11 baseline)
