Calling this target in webclient will generate and build the client screens as well as the standard client screens.
Note: As is the case with a normal build, if the build client is called prior to a build generated after model / metadata changes have been made, the client build can fail. Normally the failure would be the result of the changes made in the client UIMs / VIMs to use new features implemented on the server and then rebuilding the client without first rebuilding the server.
With evidence generation, any change made to the EUIMs / server XMLs will be automatically generated the next time the client generation occurs. This is why it is important to generate the server first if those changes affect the façade layer in any way.
