Che Theia build failing with the latest stable yarn

Describe the bug

Che Theia build failing with the latest stable yarn - 1.21.1

Steps to reproduce

Remove node_modules folder and build Che Theia with yarn.

The build is failed with several messages, like: warning package.json: Invalid bin entry for "che:theia" (in "@eclipse-che/theia-generator") or /bin/sh: theia:plugin: command not found

Looks like there’s some issue with creating symlinks in node_modules folder.

Hello @TheRealChssAddct, thanks for your feedback! cc @azatsarynnyy created the following issue: https://github.com/eclipse/che/issues/15771 to track yarn upgrade through the all projects which need these changes.

Same here. Looks it’s similar to #14145.

I found theia:plugin in node_modules/.bin/ on my workspace but it wasn’t. Only theia-plugin is available.

ls node_modules/.bin/

My workspace is on Debian GNU/Linux 9.11.

If my thought is reasonable, theia:plugin is just kept as it for the backward compatibility. And theia:plugin won’t run at least on Windows. (And in my case, also Linux.)

We can upgrade it to theia-plugin now, right ?
