Maven jaxb2:xjc failing to generate code

Question

I have added the following plugin into the Maven build in pom.xml

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxb2-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>xjc</goal>
            </goals>
            <configuration> 
                <extension>true</extension>                             
                <clearOutputDir>false</clearOutputDir>
                <schemaDirectory>${basedir}/src/main/resources/xsd</schemaDirectory>
                <schemaFiles>myapp.xsd</schemaFiles>                                                        
                <outputDirectory>${basedir}/src/main/java</outputDirectory>         
                <bindingDirectory>src/main/resources/xsd</bindingDirectory>     
                <bindingFiles>myapp-bindings.xjb</bindingFiles>
            </configuration>
        </execution>
    </executions>                       

</plugin>

Following is the build error.

[INFO] Ignored given or default xjbSources [C:\WorkSpace\MyApp\src\main\xjb], since it is not an existent file or directory.
[INFO] Ignored given or default sources [C:\WorkSpace\MyApp\src\main\xsd], since it is not an existent file or directory.

I am confused, why is the plugin not referring to the paths and files specified in the configuration.

Answer 1

Version 2.1 has changed how sources are specified

http://mojo.codehaus.org/jaxb2-maven-plugin/xjc-mojo.html#sources

e.g

<configuration>
...
  <sources>
     <source>some/explicit/relative/file.xsd</source>
     <source>/another/absolute/path/to/a/specification.xsd</source>
     <source>a/directory/holding/xsds</source>
 </sources>
</configuration>

I'm having a whole world of other problems so sticking with 1.6 as jshark suggested is a good plan

Keefer

Damn, it's likes changes everywhere. I'm migrating a system from JDK7 to JDK11, and it's a whole can of worms with getting XSD working right. – Salpingotomy

how to have the generated classes inside a certain package – Robbie

For Java 11, better to stick with version1.5! See medium.com/@nihatonder87/… – Hunks

Answer 2

version 2.1 has a bug.

You can use <version>2.2</version> with the new syntax:

<configuration>
...
  <sources>
     <source>some/explicit/relative/file.xsd</source>
     <source>/another/absolute/path/to/a/specification.xsd</source>
     <source>a/directory/holding/xsds</source>
 </sources>
</configuration>

You can use <version>1.6</version> with the old syntax:

<configuration>
    ...
    <schemaDirectory>${basedir}/src/main/resources/xsd</schemaDirectory>
    <schemaFiles>myapp.xsd</schemaFiles> 
</configuration>

Answer 3

I had the same problem today, and resolved it by putting:

<version>1.6</version>

on the plugin definition (which is in general good practice to do)

Answer 4

I got it working by setting compiler version to JDK 1.8 and jaxb2-maven-plugin version 1.5 According to the documention it will work with minimum JDK 1.6 [ The link may drop dead if its changed in the site]. For example :

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mntq.jaxb.xsd.to.pojo</groupId>
  <artifactId>XsdToPojo</artifactId>
  <version>0.0.1-SNAPSHOT</version>


  <build>
        <finalName>PersistencePoJO</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
             <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>jaxb2-maven-plugin</artifactId>
            <version>1.5</version>
            <executions>

We can also use as below:

           <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>jaxb2-maven-plugin</artifactId>
            <version>1.5</version>
            <executions>
                <execution>
                    <id>id1</id>
                    <goals>
                        <goal>xjc</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>src/main/java</outputDirectory>
                        <clearOutputDir>false</clearOutputDir>
                        <packageName>com.subu.xsd.model</packageName>
                        <schemaDirectory>src/main/java/schemadir</schemaDirectory>
                        <schemaFiles>XYZ.xsd</schemaFiles>
                    </configuration>
                </execution>
            </executions>
        </plugin>

Answer 6

For the recent ones, you might want to try this (which worked for me)

  <dependencies>
    <dependency>
      <groupId>org.glassfish.jaxb</groupId>
      <artifactId>jaxb-runtime</artifactId>
      <version>2.3.2</version>
    </dependency>
    <dependency>
      <groupId>com.sun.activation</groupId>
      <artifactId>jakarta.activation</artifactId>
      <version>1.2.1</version>
    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>jaxb2-maven-plugin</artifactId>
        <version>2.4</version>
        <executions>
          <execution>
            <id>xjc</id>
            <goals>
              <goal>xjc</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <packageName>......</packageName>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-xjc</artifactId>
            <version>2.3.2</version>
          </dependency>
          <dependency>
            <groupId>com.sun.activation</groupId>
            <artifactId>jakarta.activation</artifactId>
            <version>1.2.1</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>

or (might be a potential solution)

<dependency>
   <groupId>jakarta.xml.bind</groupId>
   <artifactId>jakarta.xml.bind-api</artifactId>
   <version>${jakarta-xml-api.version}</version>
</dependency>

For reference refer this or this.

Answer 7

I resolved it by checking "Force Update of Snapshot/Release" option in eclipse maven update.

It forces it to update all of the related dependencies.

Answer 8

It will be works, if you just add xerces dependency to end of your jaxb plugin declaration. It's so simple: the plugin just need some class to execution. Give it him now :) I. Senatov.

Rauwolfia

No, not needed, because the jaxb2-maven-plugin does not rely on xerces to work. I just tried it, with and without your tip, it wasn't even loaded. I don't understand, why you drop your pom snippet here. Did you read the Exception from the OP? The problem here is, that no Schema was found, not a compile error, due to some missing library. – Mazur

Answer 9

In my case, I had it work by downgrading my jdk compilateur version from jdk 10 to jdk 1.8

Answer 10

In some cases you should use mvn clean before build for example

mvn clean compile

you can try different plugin like
