Android Studio how to run gradle sync manually?

Question

Android studio should have this button in the toolbar marked "Sync project with Gradle Files"

EDIT: I don't know when it was changed but it now looks like this:

EDIT: This is what it looks like on 3.3.1
OR by going to File -> Sync Project with Gradle Files from the menubar.

WARNING: --recompile-scripts command has been deprecated since gradle's version 5.0. To check your gradle version, run gradle -v.

./gradlew --recompile-scripts

it will do a sync without building anything.

---

Alternatively, with command line in your root project

./gradlew build

It will sync and build your app, and take longer than just a Gradle sync

To see all available gradle task, use ./gradlew tasks

In Android Studio 3.3 it is here:

According to the answer https://stackoverflow.com/a/49576954/2914140 in Android Studio 3.1 it is here:

This command is moved to File > Sync Project with Gradle Files.

Keyboard shortcut lovers can add a shortcut for running gradle sync manually by going to File -> Settings -> Keymap -> Plugins -> Android Support -> Sync Project with gradle files (Right click on it to add keyboard shortcut) -> Apply -> OK and you are done. Choose any convenient key as your gradle sync shortcut which doesnot conflict with any other shortcut key, (I have choosen Shift + 5 as my gradle sync key), so next when you want to run gradle sync manually just press this keyboard shortcut key.

I presume it is referring to Tools > Android > "Sync Project with Gradle Files" from the Android Studio main menu.
