Rollup does not error when full plugin name is passed onto the command line

[TimvdLippe]

• Rollup Version: 2.18.0
• Operating System (or Browser): n/a
• Node Version (if applicable): n/a
• Link to reproduction (IMPORTANT, read below): https://repl.it/repls/DistortedBasicJavadocs#.replit

Expected Behavior

Specifying a plugin name that does not have any effect should return an exit code 1. E.g. The following command should fail:

npx rollup -c --plugin rollup-plugin-terser

For the code snippet:

console.log('main entry');

const this_should_be_minified = 42;

function addAFunction() {
  return this_should_be_minified;
}

console.log(addAFunction());

Actual Behavior

The commandline silently accepts the name, but does not do anything. E.g. it rolls up, but does not minify and keeps the original source file intact.

The correct version should have been

npx rollup -c --plugin terser

If you run this command, then it correctly minifies and exits cleanly:

console.log("main entry");console.log(42);
