Shadow-cljs: Depending on latest core.async breaks shadow-cljs

Created on 18 Jan 2018  路  1Comment  路  Source: thheller/shadow-cljs

Depending on [core.async "0.4.474"] causes shadow-cljs not to start, 0.3.465 works though.

shadow-cljs - config: /home/asp/projects/logview/shadow-cljs.edn version: 2.0.133
shadow-cljs - updating dependencies
shadow-cljs - dependencies updated
shadow-cljs - starting ...

I bumped the version shadow-cljs uses in version [email protected].

The issue was related to AOT compilation.

  • Starting shadow-cljs without the newer version first would AOT compile against the core.async version used by shadow-cljs itself (was 0.3.465).
  • The AOT compile only happens when the shadow-cljs version changes so it would not recompile when only core.async changes.
  • The newer core.async version however removed the Mutex class which the old AOT classes still tried to access.
  • I really hate AOT.
