Suggestion : contribute "extract variable" and "extract method" Code Action kinds

[dlicois]

Hello,

vscode-java introduced "extract to variable" and "extract to method" refactoring as quick-fixes a while ago. #303 #459

However, the extension doesn't contribute Code Action kinds or commands, as the typescript extension does.

Code Action kinds are specified by extensions using the enhanced CodeActionProvided API

https://code.visualstudio.com/docs/editor/refactoring#_keybindings-for-code-actions

https://github.com/Microsoft/vscode/blob/758206be09ddfaac46e941a77375ec34ed928b4b/extensions/typescript-language-features/src/features/refactor.ts#L107

Adding "refactor.extract.function", "refactor.extract.constant" and "refactor.extract.variable" code action kinds would allow contribution to keybinds for direct "extract method" refactoring. Which would be useful for vscode-eclipse-keybindings extension (Alt+Shift+m and Alt+Shift+l keybinds).

should be doable now that the server returns code actions. we need to adjust the code action kinds on the server side though.

The server side already adjusted the code action for refactor.extract. Need update for organize import, the PR should be ready by the end of this week.

See eclipse-jdtls/eclipse.jdt.ls#909

Key mappings can now point to

• refactor.extract.function
• refactor.extract.variable
• refactor.extract.constant
