It appears that newly-added src/test/cljs_build/npm_deps_test/invoke.cljs was not included in a recent commit.
If you do
lein test :only cljs.build-api-tests/test-npm-deps-invoke-cljs-3144
you can repro the issue with
ERROR in (test-npm-deps-invoke-cljs-3144) (FileInputStream.java:-2)
Uncaught exception, not in assertion.
actual: java.io.FileNotFoundException: src/test/cljs_build/npm_deps_test/invoke.cljs (No such file or directory)
