Heroku is runnign lein uberjar to build my Clojure app, but I need it to run lein ring uberjar. Can this be configured without forking the buildpack?
I've tried setting the web process to just use lein ring server-headless to start, instead of the standalone jar, but then I get boot timeouts while dependencies are installing.
As described here there is the LEIN_BUILD_TASK configuration variable which you can set.
I'm assuming that setting it's value to ring uberjar should work for you.
If you check the source code of the buildpack, the process fallbacks to uberjar when the LEIN_BUILD_TASK variable is not specified.
