Thanks @pauldraper for your contribution. Disabling compression sounds like a reasonable default. Also you could achieve a similar effect by using Your code looks good. Could you implement a new test that sets the |

We shouldn't scope this. The setting is already prefixed with debian. I just realised it after reading the tests.

If this is a bit too much refactoring for you, I can adjust that after merging.

It seems that debian... keys are scoped to the Debian config whenever possible.

This more a bug then a feature :( I think we clean this up in another PR. Thanks a lot for your work :)
Representative example:
A Play project takes 30 seconds for
dpkg-debto build a 70MB deb with compression.The same project takes 1 second to build a 79MB deb without compression.
Since JARs are already compressed archives, a sensible default is to not compress them again. (In fact, I'd be surprised if the small gains in client downloads weren't almost entirely overcome by the time to decompress.)
Users can use
debianNativeBuildOptionsto override options fordpkg-debif they would like a different compression type, level, etc.
