Possible to add dependency within leiningen plugin dynamically?
Eg: I have a leiningen plugin I'm building that calls some jdbc stuff, but the specific driver would be specified in the project that brings in my plugin as a dependency. Would this be possible? If so, how would I go about it? Was looking into leinjacker, but having trouble accomplishing what I want.

Re: Possible to add dependency within leiningen plugin dynamically?
Shantanu, thanks for the reply; yes, that definitely seems like a similar
situation. I will take a close look at that code tomorrow.
Here is the example that you requested:
Entry point for the plugin:
https://github.com/ckuttruff/clj-sql-up/blob/master/src/leiningen/clj_sql_up.clj
Function that is called:
https://github.com/ckuttruff/clj-sql-up/blob/master/src/clj_sql_up/migrate.clj
Example project.clj that uses the plugin:
(defproject foo 0.1.0
:plugins [[clj-sql-up 0.1.0]]
:clj-sql-up {:database jdbc:postgresql://localhost:5432/slackz?slackz})
Leiningen call:
lein clj-sql-up migrate
** Note: I know there are some existing tools to manage db migrations, but
I'm developing this in large part to learn more about leiningen / writing
plugins.
Thanks again,
-Chris

Re: Possible to add dependency within leiningen plugin dynamically?
Brilliant! worked perfectly for me... found the magic you were referring to in load-deps ( https://github.com/kumarshantanu/lein-servlet/blob/master/plugin/src/leiningen/servlet.clj#L35 ) and the pomegranate/add-dependencies call ( https://github.com/cemerick/pomegranate/blob/master/src/main/clojure/cemerick/pomegranate.clj#L57 ) Thanks so much for sharing... btw, how does that require work for the pomegranate when it isn't listed in your project.clj dependencies. seems like some chicken and egg type problem -Chris On Thursday, July 11, 2013 12:19:03 AM UTC-7, Shantanu Kumar wrote: On Thursday, 11 July 2013 12:24:34 UTC+5:30, Chris Kuttruff wrote: Eg: I have a leiningen plugin I'm building that calls some jdbc stuff, but the specific driver would be specified in the project that brings in my plugin as a dependency.

Pomegranate is included as one of Leiningen's dependency so it's available to all leiningen plugins by default. More specifically, Leiningen depends on Leiningen-core, which in turn depends on Pomegranate as you can see at the URLs below: https://github.com/technomancy/leiningen/blob/master/project.clj#L9 https://github.com/technomancy/leiningen/blob/master/leiningen-core/project.clj#L11 Shantanu -- -- You received this message because you are subscribed to the Google Groups Clojure group.
