Mezel project is not importable out of the box #39

While trying to import mezel build (i mean the mezel repo itself), these logs are being written to metals.log:

Can you run bazel info in the project.

The error would indicate that output_base should be missing from the bazel info result.

output_base is there 🤔

Thats seems helpful.

Recently a PR was merged to support apple processors, I suppose that may have caused issues?

Can you verify that the problem was introduced between 0.2.6 and 0.2.7?

susliko commented 2 months ago

Trying older versions gives the same results

How to make use of mezel-local.json? I could debug which path causes "No such file or directory"

sbt assembly should produce a target/mezel.jar.

Mezel expects bazel to be on PATH. It seems like you use bazelisk, could that be related to the issue? I use an alias for bazelisk named bazel.
