xjc tool configuration on my ant build.xml is

<xjc destdir="${src.java.generated.dir}" package="task.config" readonly="false" removeOldOutput="yes" extension="true">
            <classpath>
                <pathelement location="${libs.dir}/jaxb/jaxb-xjc-4.0.2.jar"/>
            <pathelement location="${libs.dir}/jaxb/jaxb-jxc-4.0.2.jar"/>
            <pathelement location="${libs.dir}/jaxb/jaxb-core-4.0.2.jar"/>
            <pathelement location="${libs.dir}/jaxb/jaxb-impl-4.0.2.jar"/>
            </classpath>
            <schema dir="${config.location}" includes="task.xsd" />
            <binding dir="${config.location}" includes="task.xjb" />
            <produces dir="${src.java.generated.dir}/task/config" />
            <arg value="-no-header" />
        </xjc>

Tried many solutions like:

a. Adding the jaxb-xjc-4.0.2.jar,jaxb-jxc-4.0.2.jar,jaxb-core-4.0.2.jar,jaxb-impl-4.0.2.jar in classpath as mentioned in the above code. b. Tried adding the mentioned jars in build.path too but still same error.

anyone please assist on to resolve this?

  • Does this answer your question? [java.lang.NoSuchFieldError: REFLECTION](https://stackoverflow.com/questions/25765238/java-lang-nosuchfielderror-reflection) – aled Jun 05 '23 at 11:31
  • Thanks for the quick response @aled checked the link you shared but it did not help much, all my jaxb jars are of same versions. I also tried to add many other jaxb jars too like javax.activation-1.2.0.jar,javax.activation-api-1.2.0.jar etc in classpath as well as build.path but still same error – user4888455 Jun 05 '23 at 12:29

  • You should share the full classpath used. Unfortunately ANT doesn't has dependency management like Maven so it is hard sometimes to say how jars may be conflicting. – aled Jun 06 '23 at 13:05
  • There are several other answers here that may be related to your issue https://stackoverflow.com/a/46414630/721855, https://stackoverflow.com/a/50251510/721855 , https://stackoverflow.com/questions/65632952/include-library-for-jaxb-into-jar-file-without-using-maven. Have you searched for other answers here? Note that you seem to using the old com.sun.xml.bind that are deprecated and removed in Java 11. You should upgrade: https://blog.payara.fish/how-to-update-an-application-using-jaxb-from-jdk-8-to-jdk-11 – aled Jun 06 '23 at 13:19
