Clojure dependencies require only JARs to work. Downloading POMs is both a waste of time, space, and bandwidth. In addition POMs create edge cases that we would have to handle, an would rather avoid. For example, the `guice` package which shows up in the classpath includes a JAR named `guice-4.2.2-no_aop.jar`. The issue with that is that there is no corresponding POM in the directory: https://repo1.maven.org/maven2/com/google/inject/guice/4.2.2/ Either we have to make a special case for such packages, or we can just skip POMs entirely and avoid the mess.

# Description
|
|
|
|
This folder contains the scripts and Nix derivations necessary to generate Clojure dependencies for this project.
|
|
|
|
# Usage
|
|
|
|
Running [`generate.sh`](./generate.sh) in a shell that has available `shadow-cljs` and `clojure` should update the `deps.list` and `deps.json` files.
|
|
|
|
# Details
|
|
|
|
By using the following command:
|
|
```sh
|
|
shadow-cljs classpath --force-spawn
|
|
```
|
|
We download the necessary JARs into `~/.m2` folder, but also get the classpath printed into standard output.
|
|
We skip POM files since they are not necessary, and add edge cases we don't want to handle.
|
|
|
|
We then use the classpath in combination with contents of `~/.m2` folder to generate the following files:
|
|
|
|
* `deps.list` - List of JARs relative to the `~/.m2` cache folder.
|
|
* `deps.json` - Full list of JARs including their SHAs.
|
|
|
|
The `deps.list` file is just intermediate and for debugging purposes.
|
|
The `deps.json` is loaded by the derivation in [`default.nix`](./default.nix) and used to produce a derivation that contains all the necessary dependencies:
|
|
|
|
```
