I\'m wondering if there is a way to force Heroku to recompile the slug without pushing new commits and/or updating the config variables.
Why would I want to do this?
Slug compilation is invoked with a git pre-recieve hook, so the only way to recompile is to push a new commit.
For completeness see this article on Heroku for the slug compiler. It discussed the use of the pre-recieve hook to invoke the slug compile process under the Compilation heading.
Looks like this is not yet available. However, a feature request has be opened on the heroku github repo
It also mentions "an alternate way to build that is not reliant on git push
"
