I'd like to share with you my current procedure, with some manual steps, to create a quarterly release workspace in Liferay Dev Studio.

Update blade

In a command line window, run blade update.

Create a Liferay Workspace

Quarterly releases do not appear in the dropdown. Just pick any Liferay DXP 7.4 version and don't download the bundle.

Update settings.gradle

Make sure you have the latest gradle plugins.

Currently, it is : classpath(group: "com.liferay", name: "com.liferay.gradle.plugins.workspace", version: "10.0.6")

Update gradle.properties

For example, liferay.workspace.product = dxp-2024.q1.6

Run initBundle

Under Gradle Tasks, run bundle -> initBundle

And wait a little bit.

And manually add the server once the download is complete.
