Run the prep task of dependent libraries where applicable.
To avoid unnecessarily running in all sub modules, predicated
on :exoscale.project/needs-prep? in the deps edn file.
This is implicitly ran for check, jar, and uberjar and thus is only useful
as a debugging facility.
clojure -T:project prepWhen a :exoscale.project/modules key is present in the project's
configuration, runs through all configured module to call the
prep target instead of running on the project, only accounting
for those having :exoscale.project/needs-prep? set to true.
In standalone projects, the flag is not honored and clojure -X:deps prep
is ran regardless.
