Feedback on the example

Hello rules_clojure - I appreciate the thought and effort that went into these rules!

I have been upgrading a project that previously used https://github.com/simuons/rules_clojure.

The example in the examples directory is incomplete so it took me a while to get something running.

• With bazel 5.4.1 I was unable to run anything from the example directory - for example

$ cd examples/setup/default/
$ bazel build //...

• I created a standalone project where I had more success
  https://github.com/humphrej/rules_clojure_example
• I wasn't able to get it working as per the example where the WORKSPACE+BUILD+example.clj are all in the top level folder.
• With a folder underneath the WORKSPACE and using resource_strip_prefix it worked fine
• Other gotchas not present in the original example:
  • aot is mandatory
  • clojure dependencies need to be specified explicitly

Start in examples/setup/default/ by reading WORKSPACE, BUILD, and example.clj, then run bazel build //... with Bazel 5.4.1 to reproduce the reported failure. Compare the standalone rules_clojure_example project, including its resource_strip_prefix, aot, and explicit dependency setup; done means the repository example is complete and builds successfully.
