Selectively Turning off certain buildpacks

[mattmadhavan-gmail]

IIs it possible to selectively turn off certain buildpacks from being auto-detected and brought in?

It depends on the buildpack. All buildpacks have a set of detection criteria. If the criteria for the buildpack you want to disable is something that you can externally influence, like a file existing or an env variable being set, then yes. You can disable those buildpacks by preventing that criteria from being met.

Not all buildpacks have external criteria though and some are required to get successful builds.

That's all very generic, sorry, but it really does depend on the buildpacks. Which buildpacks are you using?
