I have a problem with accessing credentials from ~/.aws file with lein I’m using the `datomic.client.api` library, that has a function called `client` which takes in a map that contains a named profile in the `~/.aws/credentials` like so:

(client {
               :server-type :ion
               :region "us-east-1" ;; e.g. us-east-1
               :system "humboi-march-2021"
               :endpoint ""
               :creds-profile "humboi" ;;;;;;;;; NAMED PROFILE
               :proxy-port 8182
  })

However, when I do `lein run` or lein repl, I get the error that `profile file cannot be null`:

Syntax error (ExceptionInfo) compiling at (/private/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/form-init6639201664669188954.clj:1:125).
profile file cannot be null

However, when I create an uberjar and run that, I get no such error. What might be causing this and how do I fix it?

getting a full stacktrace would be a good first step you can accomplish so with :jvm-opts ["-Dclojure.main.report=stderr"]

sorry, nothing comes to mind. I'd double-check that ~/.aws/credentials exists, has correct syntax and that the clojure can slurp it (i.e. that there are no File permissions issues) if that fails, you might have better luck in #datomic

zendevil.eth16:03:50

I tried at #datomic but they say that they don’t actively use leiningen, and this seems to be a leiningen issue

vemv17:03:11

honestly it doesn't look like a Leiningen issue to me. Leiningen does not affect the set of available files for the JVM to read. the only 'special' thing it might do is setting a PWD. But it shouldn't matter because ~/.aws is not a filename relative to the PWD

quoll18:03:13

This may just be me, but I’m encountering a new problem after I updated to Leiningen 2.9.5 recently. Some dependencies aren’t making it into the dependency tree for my projects. Say I have project A, which depends on project B, and then project B depends on an external lib C. When I build B everything works fine, and the .pom file deployed to Clojars includes the reference to C (as expected). But then when I go back to project A, it fails to build. Running lein deps :tree shows that C is missing (as if I’d excluded it). I can explicitly include a dependency on C, and it works, but I’m wondering why this is happening. The first time it happened was with a dependency on Cheshire failing to pick up part of jacksonXML. In this case, Asami depended on Zuko, which used Cheshire. Part of the dependency tree for Asami looks like this: Asami

[org.clojars.quoll/zuko "0.4.6"]
   [cheshire "5.10.0"]
     [com.fasterxml.jackson.core/jackson-core "2.10.2"]
     [com.fasterxml.jackson.dataformat/jackson-dataformat-cbor "2.10.2"]
     [com.fasterxml.jackson.dataformat/jackson-dataformat-smile "2.10.2"]
     [tigris "0.1.2"]

This was perfectly correct. Then I have a project which depends on Asami. The :dependency section for that project is:

:dependencies [[org.clojure/clojure "1.10.2"]
                 [org.clojure/clojurescript "1.10.773"]
                 [prismatic/schema "1.1.12"] 
                 [org.clojars.quoll/asami "2.0.0-alpha4"]
                 [aysylu/loom "1.0.2"]]

This ought to pick up everything that is in Asami, right? But it failed to run. When I looked at the deps tree, I got this:

[org.clojars.quoll/zuko "0.4.6"]
     [cheshire "5.10.0"]
       [com.fasterxml.jackson.dataformat/jackson-dataformat-cbor "2.10.2"]
       [com.fasterxml.jackson.dataformat/jackson-dataformat-smile "2.10.2"]
       [tigris "0.1.2"]

I’d expect this if I’d had an exclusion, but I didn’t. I got around it by adding an explicit dependency:

[com.fasterxml.jackson.core/jackson-core "2.10.2"]

It bothered me that I couldn’t see what was causing it, but it had an easy workaround, so I got back to what I was doing. But then it happened again in another project, and I had to work around it again. So I’m checking in to see if anyone else has been seeing anything like this. Or maybe I’m doing something weird and I didn’t notice when I changed it.

vemv17:03:07

> This ought to pick up everything that is in Asami, right? But it failed to run. When I looked at the deps tree, I got this: sometimes in a the given deps :tree report, the line you're looking for might reside under some other leaf e.g. jackson deps can be scattered across the report

vemv17:03:55

A more interesting behavior we found is that deps :tree would not render at all some items that actually are computed. I believe lein classpath never lies, whereas lein deps :tree is more of a best-effort explanation of what is being computed Feel free to ask over Webex if this sounds like a good lead :)

quoll00:03:33

Unfortunately, it’s not. It’s (intentionally) a small dependency tree. Asami has the dependency, and uses it. Asami-Loom picks up Asami, Loom, and not much else. For some reason, it wasn’t picking up jackson-core as a transitive dependency. It wasn’t that deps :tree didn’t show it, it’s that the application wouldn’t start, since Cheshire complained. deps :tree was what revealed that jackson-core was missing. I can’t for the life of me see why. Importing it explicitly fixed it. But it SHOULD have come in transitively. Other projects using Asami were bringing it in. But this one didn’t.

vemv00:03:12

weird! no :managed-dependencies in play either?

quoll03:03:10

I’m actually unaware of that option, so that’s a definite “no”
