I don't think <includeSchema>**/*.xsd</includeSchema> is valid syntax for jaxb2-maven-plugin:xjc Try omitting that parameter.

If you don't specify schemaFiles it should use all XSD files in the schemaDirectory.

"schemaFiles -- List of files to use for schemas, comma delimited. If none, then all xsd files are used in the schemaDirectory. This parameter also accepts Ant-style file patterns." (see jaxb2-maven-plugin documentation)

BTW, it is usually a good idea to use maven's configuration parameters to refer to a directory. For example, change <schemaDirectory>src/main/resources/xsd</schemaDirectory> to <schemaDirectory>${project.basedir}/src/main/resources/xsd</schemaDirectory>.

Finally, you might also want to refer to this similar SO post.
