```auto
_$ shadow-cljs watch modern-cljs_

```

**Error Prompt:**

```auto
Invalid Filename, got cljs/modern_cljs/core.cljs but expected modern_cljs/core.cljs (or .cljc)

```

**My shadow-cljs.edn file:**

```auto
    {:source-paths ["src"]
     :dependencies []
     :builds {:modern-cljs {:output-dir "public/js"
                            :asset-path "/js"
                            :target :browser
                            :modules {:main {:entries [modern-cljs.core]}}
                            :devtools {:http-root "public"
                                       :http-port 8080}}}}

```

**Directory Structure (inside _modern-cljs_ folder):**

build.boot package.json public shadow-cljs.edn src

```auto
./public:
index.html js

./public/js:
cljs-runtime main.js manifest.edn

./src:
cljs

./src/cljs:
modern_cljs

./src/cljs/modern_cljs:
core.cljs login.cljs

```

As the error shows the expected filename is `modern_cljs/core.cljs` but you have `cljs/modern_cljs/core.cljs`. So you should be using `:source-paths ["src/cljs"]`. The expected name is expected to be found on any of the `:source-paths` or in your `:dependencies`.
