# `mix masu.release_check`
[🔗](https://github.com/hattoriai/masu/blob/v0.1.0/lib/mix/tasks/masu.release_check.ex#L1)

Checks the built files before a release of Masu.

    $ mix masu.release_check

This task is for work on Masu itself; the `release` alias runs it
after `mix masu.build` and before `mix hex.publish`. In any project
but Masu, it stops with an error. It fails when:

  * one of the four bundle files (`masu.esm.js`, `masu.cjs.js`,
    `masu.css` and `masu-sumi.css`) is missing from `priv/static`,
    or is empty (the empty files that CI makes are not a build);
  * `priv/static` holds any other file or directory;
  * the `version` of `package.json` is not the version of `mix.exs`.
