Describe the bug

The benchmarks are crashing out of the box.

What is the expected behaviour?

It crashes.

How can the behaviour be reproduced?

1. Clone the repo (I'm using main which as of time of report is 97eb463b8c71c60f9ff261db795ee679e4e78767)
2. Copy and paste the provided benchmark examples
3. Observe that it crashes

All 3 provided examples crash with similar logs. For example:

$ TIMBRE_LEVEL=':warn'  clj -M:benchmark run -f :query -q :simple-query -i 10
Compile-time (elision) Timbre min-level: :warn
Syntax error (ClassNotFoundException) compiling at (datahike/impl/entity.cljc:1:1).
datahike.java.IEntity

Could you check what happens if you run clj -T:build compile and then run the benchmarks again? Looks like somehow the java bindings are used in here but I don't understand why it is used in the benchmark. Maybe @jsmassa has also some ideas on what might go wrong here.

Hi @kordano! I had the same issue as the issue reporter, and can confirm that running clj -T:build compile beforehand fixes the benchmarks.

Thanks!

[Ramblurr]

Also can confirm that fixes it. Maybe just add a small note to the docs? Compiling beforehand is painless enough.

$ clj -T:build compile
...
$ TIMBRE_LEVEL=':warn'  clj -M:benchmark run -f :query -q :simple-query -i 10

I am assigning this to me because there should be this in the deps.edn.

I will also improve the docs.
