[jira] [Updated] (CAY-1622) Generated classes shouldn't produce
serialVersionUID compiler warning (ROP super only)
[ https://issues.apache.org/jira/browse/CAY-1622?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrus Adamchik updated CAY-1622:
---------------------------------
Summary: Generated classes shouldn't produce serialVersionUID compiler warning (ROP super only) (was: Generated classes shouldn't produce serialVersionUID compiler warning)
The moment I closed this, I realized that the patch may be useful for the ROP superclass. So reopening, and changing the title to ROP
> Generated classes shouldn't produce serialVersionUID compiler warning (ROP super only)
> --------------------------------------------------------------------------------------
>
> Key: CAY-1622
> URL: https://issues.apache.org/jira/browse/CAY-1622
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 3.0
> Reporter: Bob Harner
> Priority: Minor
> Attachments: serial-version-uid.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.
