All, Gerrit ticket: http://gerrit.ovirt.org/#change,2164 was just merged, This commit removes the SharedGwt module from oVirt maven structure, This module aggregated backend source code of three modules: Common, Compat and SearchBackend for UI (gwt) modules during compile phase, This is replaced now by a direct access to the backend modules using sources artifacts, GWT module descriptor of SharedGwt maven module (named: SharedGwt.gwt.xml) contained a list of java classes that should be visible for the GWT compiler, Since this module does not exist anymore, this file was split into three files per backend module: Common.gwt.xml - Contains backend Common code that is visible to GWT compiler. SearchBackend.gwt.xml - Contains SearchBackend code that is visible to GWT compiler. Compat.gwt.xml - Contains backend Compat code that is visible to GWT compiler. To avoid pushing UI related files directly into the backend modules, these files are located in gwt-common module, which contains shared code for UI modules. In short: any backend source code that should be available during UI compilation which exist in Common|Compat|SearchBackend must be included in the appropriate GWT module descriptor according to its parent module. Please contact me if this is causing any issue, Regards, +972-543094949 Asaf.
