Clojurians Log v2
leiningen
This is probably a FAQ, but Google search did not find me the answer I need.
I have a leiningen project which depends upon few libraries, which are fetched from Maven Central and Clojars.
However, I want to patch one of the libraries and depend upon the patched version of the library.
I successfully rebuilt the library after patching it and I have its jar file locally.
I want my project.clj to declare dependency upon the local jar file rather than upon the Maven Central/Clojars version.
How to specify this in the :dependencies clause in project.clj?
Thanks!
Simplest thing would be to release your jar in Clojars, depend on it, and apply :exclusions so that the original jar won't be depended on
Use lein deps :tree to confirm that the original is zapped
Hope it helps!
For me it is not the simplest thing to do. Requires me to expose half-baked buggy code to the world. The most obvious thing to do is to have a way to depend upon a local jar, and this is what I am looking for.
I found https://clojure.org/reference/deps_edn
It specifies the following format for deps.edn:
;; Local jar
localjar/name {:local/root "path/to.jar"
:exclusions [lib1 lib2]}}[target/name {:local/root "/path/to/target/name-0.11.1-beta-standalone.jar"}]
and got the following error message from lein deps:
java.lang.IllegalArgumentException: Bad artifact coordinates target:name:jar:{:local/root "/path/to/target/name-0.11.1-beta-standalone.jar"}, expected format is <groupId>:<artifactId>[:<extension>[:<classifier>]]:<version>
(there may be inaccuracies, because I censored the real names)
It is not clear to me how to write the expected format in my case.You can also add the .jar to :resources
If you locally install your modified project, you can depend on it as a normal maven dep
Lein doesn’t support local jars like deps
How to do that depends on the other projects build - mvn install or lein install should do this for you
> Lein doesn’t support local jars like deps Not as a first-class feature, but adding a .jar to :resources works Local install is also OK, perhaps a little less reproducible (you'd have to make sure to do the same locally and in CI prior to test running, deployments, etc)
