Plugin order causes issues

[zcuric]

Hi, when trying to fix the build for vue-plyr (https://github.com/redxtech/vue-plyr/issues/60) by updating to bili@4 (see here: https://github.com/zcuric/vue-plyr/pull/1) I encountered an issue when using specific babel config with vue files (I was trying to solve this actually: https://github.com/rollup/rollup-plugin-babel/issues/260).

Error I got was this:

error Failed to bundle src/index.js in cjs format

Stack Trace:
SyntaxError: /Users/zdravko/Code/vue-plyr/src/VuePlyr.vue: Unexpected token (1:0)

After debugging, we concluded that was probably because of order of plugins, which we test by moving https://github.com/egoist/bili/blob/28b1a197eb41dac2582814253f6b2b9226310d21/src/index.ts#L290-L301

to here: https://github.com/egoist/bili/blob/28b1a197eb41dac2582814253f6b2b9226310d21/src/index.ts#L216

In bili@3 this wasn't an issue, probably because of the way the plugins were defined, array was used in that config.

So, there should be a way to define the plugin priority or order of execution to fix these kind of errors.

It should be fixed in 4.5.2

So isn't this done?! Why not to close?

I encountered problems using @rollup/plugin-eslint.

// bili.config.ts
import { Config } from 'bili';

const config: Config = {
  input: 'src/index.ts',
  output: {
    format: ['cjs', 'esm']
  },
  plugins: {
    '@rollup/plugin-eslint': {
      throwOnError: true
    }
  }
};

export default config;

The problem is that bili puts this plugin in last place, so it's linting transformed code and not the original one.
