java - JAXB maven plugin not generating classes -


i trying generate java files xsd, below code doesn't generate. if uncomment outputdirectory, works delete folder first. adding clearoutputdir = false not generating anything.

<build>         <plugins>             <!-- jaxb xjc plugin invokes xjc compiler compile xml schema java classes.-->             <plugin>                 <groupid>org.codehaus.mojo</groupid>                 <artifactid>jaxb2-maven-plugin</artifactid>                 <executions>                     <execution>                         <goals>                             <goal>xjc</goal>                         </goals>                     </execution>                 </executions>                 <configuration>                     <!-- package in source files generated. -->                     <packagename>uk.co.infogen.camel.message</packagename>                     <!-- schema directory or xsd files. -->                     <sources>                         <source>${basedir}/src/main/resources/xsd</source>                     </sources>                     <!-- working directory create generated java source files. -->                     <!--<outputdirectory>${basedir}/src/main/java</outputdirectory>                     <clearoutputdir>false</clearoutputdir>-->                 </configuration>             </plugin>         </plugins>     </build> 

i getting message:

[info] --- jaxb2-maven-plugin:2.2:xjc (default) @ service-business --- [info] ignored given or default xjbsources [/users/aaa/development/workspace/infogen/infogen_example/service-business/src/main/xjb], since not existent file or directory. [info] no changes detected in schema or binding files - skipping jaxb generation. 

the first thing should never, ever, generate code inside src/main/java. generated code should not version-controlled , can deleted @ any-time since regenerated anyway.

generated code should located under target, build directory of maven. jaxb2-maven-plugin generate classes default under target/generated-sources/jaxb , there's no reason change that. if you're using eclipse, need add folder buildpath right-clicking , selecting "build path > use source folder".

when running maven, run mvn clean install: clean target folder , regenerate scratch: leads safe , maintainable build. you'll find solve problem: since generated classes deleted before build, correctly re-generated during next build.

of course, if generation process long , don't want each time, can run maven mvn install , configure plugin not remove generated classes setting clearoutputdir false. note that, while build faster, may not detect subsequent errors in xsd if updated.
