Dev-tools isn’t on maven central or in the datomic-cloud repository.
The e-mail that you received when you requested dev-tools will have a link to maven configuration for dev-tools.
Check to make sure that your ~/.m2/settings.xml has the correct credentials and that your deps.edn has the correct :mvn/repos “cognitect-dev-tools” key and value.
I was able to reproduce what I believe your issue was and deploy a fix.
Check and let me know of 1.0.243 is available for you now via maven.
You may need to clear the local .cpcache in the project directory and delete ~/.m2/repository/com/datomic/dev-local/1.0.243. (I had a bad pom get cached when testing the solution, and I suspect it will happen to most users who encountered this problem)
I hit this issue too, but rm -rf .cpcache ~/.m2/repository/com/datomic/dev-local/1.0.243/ didn’t seem to help at 1st glance.
It turned out that the problem was that I tried to use the Refresh Clojure Deps Projects Cursive operation, but that somehow just gave me this error:
The following errors were found during project resolve: /Users/XXX/.../deps.edn: status code: 401, reason phrase: Unauthorized (401)
The most likely issue is that IntelliJ doesn’t see the same process environment as my shell, hence it tried to access the Cognitect dev-tools maven repo (https://dev-tools.cognitect.com/maven/releases/) without the correct credentials.
The solution is to just run clojure -A:... from a shell, which should successfully download dev-local version 1.0.243.
Subsequent Refresh Clojure Deps Projects actions won’t try to download it, hence they should succeed.
