Is there anything obvious this error indicates when building an uberjar?

It seems related to my inclusion of a dependency on https://github.com/juxt/tick Is there a way to figure out which form is causing this when it's read?

@jjttjj According to follow-up on that issue, it should be fixed in tools.build 0.8.3 onward -- what version are you using?

2023-03-08T19:35:51.119699Z

Using 9.3 so it shouldn't be that. Will get a minimal repro done today

Data readers can include reader conditionals now iirc

Cljs will read the cljs branch of this file

2023-03-07T16:27:40.991809Z

Yeah I saw that. I've now found that adding:

:conflict-handlers {"^data_readers.clj[cs]?$" :warn}

in my call to build/uber seemed to "fix" this for my situation. When I do that I don't get a warning for any data-readers conflicts, and the necessary data_readers.cljc ends up in the jar. Might be relevant that I'm using a :bb reader conditional, that doesn't immediately seem like the problem though. I'll see if I can get a minimal repro at some point.

@alexmiller Seems like a bug that uber tries to merge data_readers.cljc files without supporting reader conditionals?

2023-03-07T19:44:17.344539Z

Thanks for that @seancorfield

seancorfield 2023-03-06T20:59:07.282789Z

It sounds like a data_readers file in one of your dependencies contains a reader conditional for clj/s support -- and it can't be read as EDN.

2023-03-06T21:01:13.742059Z

Ah, that explains it, thanks!
