Rebuild app without updating discourse?

Is it possible to ./launcher rebuild app without updating discourse?

You could, but you would have to specify the exact commit hash in your app.yml file.

Can you please give me an example how this would be setup?

In app.yml uncomment

#version: tests-passed

and replace tests-passed with the commit hash something like

version: f7a335a64e7146166d5fdaedcfee816997f2822d

You can find the commit hash in github if you click on the commit that you want.

Come posso trovare il commit necessario?
Ad esempio, ho la versione 2.4.0 beta2 e voglio rimanere su questa versione.

Vai su GitHub, consulta i tag e seleziona quello corrispondente alla versione desiderata.
