I have a following configuration of the plugin
If war.plugin.version is set to 2.0.1 then resulting war does not contain tech_*.properties files in its WEB-INF/classes directory.
If war.plugin.version is set to 2.1.1 then files are present.
As far as I can see this change in the behavior occurred silently - it is not mentioned in anywhere changelogs.
Is it done intentionally?
