XJC Maven Plugin(jaxb2-maven-plugin) Java 11 Migration Issues

Question

I am currently working on java 11 migration project where jaxb2-maven-plugin has been used for XJC task. As XJC executable is not present in the JDK 11 version, I am getting below mentioned errors.

    [ERROR] Failed to execute goal org.codehaus.mojo:jaxb2-maven-plugin:2.2:xjc (xjc-schema1) on project paymaster-service: Execution xjc-schema1 of goal org.codehaus.mojo:jaxb2-maven-plugin:2.2

Below is my pom.xml

<plugin>
   <groupId>org.codehaus.mojo</groupId>
   <artifactId>jaxb2-maven-plugin</artifactId>
   <version>2.2</version>
   <executions>
      <execution>
         <id>xjc-schema1</id>
         <goals>
            <goal>xjc</goal>
         </goals>
         <configuration>
            <target>2.2</target>
            <schemaFiles>SubmitPaymentBatch/SubmitPaymentRequest.xsd</schemaFiles>
            <packageName>app.test.services.submitpayment.request</packageName>
            <clearOutputDir>false</clearOutputDir>
         </configuration>
      </execution>
</plugin>

I have added necessary dependencies like JAXB, JAXB-IMPL, etc., as per java 11 requirements. But still not able to fix the issues. Do you have any suggested fix for this ? Thank in Advance.

I've just found a workaround for problems with using jaxb2-maven-plugin with Java 11. It consists of adding extra dependencies in pom.xml and adding an extra, dummy XSD file to the project, next to proper XSD files. I've put it altogether in my blog-post here: https://artofcode.wordpress.com/2019/02/26/jaxb2-maven-plugin-2-4-and-java-11/

I have fixed this issue by following below reference link.

https://github.com/davidmoten/jax-maven-plugin

As per the above tutorial reference, I have modified my plugin as below and i am able to fix this.

<plugin>
   <groupId>com.github.davidmoten</groupId>
   <artifactId>jax-maven-plugin</artifactId>
   <version>VERSION_HERE</version>

   <executions>
      <execution>
         <id>xjc-schema1</id>
         <goals>
            <goal>xjc</goal>
         </goals>
         <configuration>
            <target>2.2</target>
            <schemaFiles>SubmitPaymentBatch/SubmitPaymentRequest.xsd</schemaFiles>
            <packageName>app.test.services.submitpayment.request</packageName>
            <clearOutputDir>false</clearOutputDir>
         </configuration>
      </execution>
   </executions>
</plugin>

Hi, remove the dependencies block as it's not needed and the the configuration entries need to be in `` elements as per the `xjc` CLI command. May as well update the version to 0.1.6 (or just write VERSION_HERE so people use latest). — Dave Moten, Apr 09 '19 at 03:52

I was able to solve the issue for JDK11 by adding all dependencies which are listed here: https://github.com/apache/cxf/blob/master/distribution/src/main/release/samples/pom.xml#L251-L290 which the apache.cxf project uses in their example projects starting for JDK9

I had issues with making jaxb working with maven and Java 11 too. My solution looks as follows:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>jaxb2-maven-plugin</artifactId>
  <version>2.5.0</version>
  <executions>
    <execution>
      <id>xjc</id>
      <phase>generate-sources</phase>
      <goals>
        <goal>xjc</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <packageName>de.powerstat.my.generated</packageName>
  </configuration>
  <dependencies>
    <dependency>
      <groupId>com.sun.activation</groupId>
      <artifactId>javax.activation</artifactId>
      <version>1.2.0</version>
    </dependency>

    <dependency>
      <groupId>org.glassfish.jaxb</groupId>
      <artifactId>jaxb-runtime</artifactId>
      <version>2.3.3</version>
    </dependency>

    <dependency>
      <groupId>org.glassfish.jaxb</groupId>
      <artifactId>jaxb-core</artifactId>
      <version>2.3.0.1</version>
    </dependency>

    <dependency>
      <groupId>org.glassfish.jaxb</groupId>
      <artifactId>jaxb-xjc</artifactId>
      <version>2.3.3</version>
    </dependency>

  </dependencies>
</plugin>

Hope this helps others.
