Subject [jira] [Updated] (CAY-1622) Generated classes shouldn't produce serialVersionUID compiler warning
Date Wed, 05 Oct 2011 08:41:34 GMT


Dzmitry Kazimirchyk updated CAY-1622:

    Attachment: serial-version-uid.patch

Since we couldn't come to final decision about this issue on the dev list, I'm reverting committed
changes and attaching them as a patch.

> It is probably a good idea for Cayenne not to produce any compiler warnings, but auto-generated
entity classes always have the "The serializable class _Foo does not declare a static final
serialVersionUID field of type long" compiler warning.  
> The @SuppressWarnings("serial") annotation will get rid of the warnings, but of course
it is not recommended to manually update the generated  classes.
> Users could configure the IDE to ignore these warnings (yuk), but then other team members
will still see them.
> Another option is to for users to set up a custom velocity template to include this annotation.
> But the best solution would be for Cayenne to either automatically generate either the
serialVersionUID itself or the @SuppressWarnings("serial") annotation that suppresses the
compiler warning.
