Compilation errors of the tag version v1.6.0

[danabit]

I noticed that compiling the tag version v1.6.0, while compiling the geostore-rest-impl part, you get the following errors:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project geostore-rest-impl: Compilation failure: Compilation failure:
[ERROR] E:\Mapstore2_Projects_Repository\AbitatWebGisProject\geostore_abitat\src\modules\rest\impl\src\main\java\it\geosolutions\geostore\services\rest\impl\RESTUserGroupServiceImpl.java:[50,7] error: RESTUserGroupServiceImpl is not abstract and does not override abstract method getAll(SecurityContext,Integer,Integer,boolean,boolean) in RESTUserGroupService
[ERROR] E:\Mapstore2_Projects_Repository\AbitatWebGisProject\geostore_abitat\src\modules\rest\impl\src\main\java\it\geosolutions\geostore\services\rest\impl\RESTUserGroupServiceImpl.java:[153,4] error: method does not override or implement a method from a supertype

The same thing does not happen if you compile the version of the tag v1.5.0 instead.
