There is no formatter for 'java' files installed

Hello,

I try to format my java code with visual code.
I have try without configuration (for a default format) > and I have the message : There is no formatter for 'java' files installed
I have tried to follow https://github.com/redhat-developer/vscode-java/wiki/Formatter-settings >> then idem

Environment

• Windows 10
• JDK 12
• 1.51.1
• Java extension version: v0.12.0

Steps To Reproduce

1. Install visual code
2. Init java project (with gradle) then create a new class
3. CTRL + P > format document > There is no formatter for 'java' files installed

As said on https://github.com/redhat-developer/vscode-java/issues/1497
I have tried added "[java]": {"editor.defaultFormatter": "redhat.java"} on settings.json

(Precision : My starting java server is starting and loop at 62% Starting java language server - build parameterized mode .... gradle.eclipse .....)
(will work when I desactivate Gradle importing project (aka "java.import.gradle.enabled": false )
