--------------------------------------
Hi [~faizel]! I've pushed a fix for this [1]. Need to add more tests to check
all our tools, as I've checked only maven plugin so far.

> DataChannelMetaData is null during cgen execution
> -------------------------------------------------
>
> Key: CAY-2658
> URL: https://issues.apache.org/jira/browse/CAY-2658
> Project: Cayenne
> Issue Type: Bug
> Components: cgen
> Affects Versions: 4.2.M2
> Environment: Mac OS X 10.15.4
> Cayenne 4.2.M2
> Reporter: Faizel Dakri
> Assignee: Nikita Timofeev
> Priority: Minor
> Fix For: 4.2.M2
>
>
> During cgen execution, the {{DataChannelMetaData}} instance is not set upon
> data map load. It looks like {{CgenModule}} does not bind to the
> {{ExtensionAwareHandlerFactory}}, nor does it load the {{InfoExtension}}, so
> when the data map is loaded, the metadata instance is null. This causes
> metadata lookups to fail from the {{MetadataUtils}} class that is supplied to
> the velocity context during class generation.
> I *think* fix is to have {{CgenModule}} bind to the
> {{ExtensionAwareHandlerFactory}} and then let {{ProjectModule}} contribute
> the {{InfoExtension}}.
