title: go build: no Go files in /msfs2020-go-master
body: <p>Im trying to rebuild a golang github repository to apply some minor changes.</p>
  <p>The go application Im trying to modify is the following <a href="https://github.com/lian/msfs2020-go" rel="nofollow noreferrer">https://github.com/lian/msfs2020-go</a>
  Please use the provided github link to inspect the file tree.</p>
  <p>I used the master branch and extracted it to <code>/user/Documents/msfs2020-go-master</code></p>
  <p>If I call <code>go build</code> from <code>/user/Documents/msfs2020-go-master</code> the output equals: <code>no Go files in /user/Documents/msfs2020-go-master</code></p>
  <p>I tried deleting the <code>go.mod</code> and recreating it with <code>go mod init github.com/lian/msfs2020-go</code> followed with a <code>go mod tidy</code>
  but still <code>no Go files in /user/Documents/msfs2020-go-master</code></p>
  <p>Here the current <code>go.mod</code></p>
  <pre><code>module github.com/lian/msfs2020-go
  
  go 1.16
  
  require github.com/gorilla/websocket v1.4.2
  </code></pre>
  <p>And here the <code>go.sum</code></p>
  <pre><code>github.com/gorilla/websocket v1.4.2 h1:+/TMaTYc4QFitKJxsQ7Yye35DkWvkdLcvGKqM+x0Ufc=
  github.com/gorilla/websocket v1.4.2/go.mod h1:YR8l580nyteQvAITg2hZ9XVh4b55+EU/adAjf1fMHhE=
  </code></pre>
  <p>The master was build with 1.14 and Im using 1.16 golang.
  All my test go applications/modules run/build/install fine at a &quot;Hello World&quot; developing level.</p>
  <p>What did I do wrong? I gladly accept any input and will provide additional information's if requested.</p>
