Answer 1

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.

Answer 2

I am also using maven configuration and spent almost to compile the project stuff. Later on i came to know that it looking for the schema file i.e. schema.xsd.

If you are using the MAVEN configuration then by default you can put the schema file under the resources directory.

But if you want to specify your path for finding the schema file then you can use the includeSchema tag of schemaDescription in plugin configuration.

                                OR

You can use the effictive pom to search for specific tag also.

Command for effective pom in maven: mvn help:effective-pom
