Hi,I downloaded from sourceforge.net this Liferay Developer Studio installer (CE) 3.9.0 M1 for Linux:

LiferayWorkspacewithDevStudioCommunityEdition-202007030640-linux-x64-installer.run

I installed it under Ubuntu 20.04 with Amazon Corretto JDK 11 by invoking the installer without errors. I can also import the default Liferay workspace created by the installer. But this is for 7.2-ga2 and I want one for 7.3.3 GA4.
When I try to create a new Liferay workspace for product version portal-7.3-ga4 (in a new Eclipse workspace) the creation of the workspace stops with an error message "Can not find Liferay Gradle project builder". The portal bundle is not even downloaded. The same error occurs for product versions portal-7.3-ga3 and portal-7.3-ga2.

When I go back to product version portal-7.3-ga1 it works, the portal bundle gets downloaded and I get a new Liferay workspace.

Here are screenshots of the problem:



Is this a known bug in the 3.9.0 M1? Is there a workaround?

Thanks,
Thomas
