Suppress Unnecessary @SuppressWarning("deprecation")

[alexkoay]

Is there any way to suppress such errors?
I'm using protobuf to generate some Java code and a ton of such warnings (the only ones) are appearing.

Alternatively is there a way to configure the LS to ignore certain files / directories / packages?

Yes. Though not well documented :

If you create a file under your workspace folder called .settings/org.eclipse.jdt.core.prefs and populate it with :

org.eclipse.jdt.core.compiler.problem.unusedWarningToken=ignore

This should disable it. There's an issue (with PR) that will hopefully simplify this process a lot by introducing a code action to autmoatically allow ignoring these options. redhat-developer/vscode-java#1791 .

You can also customize the location of the settings file with java.settings.url . There is a pretty good description of this at https://github.com/redhat-developer/vscode-java/wiki/Settings-Global-Preferences but the property discovery is what we hope to improve.

Marking this as closed. The issue I referenced from above is where we hope to make it easier to discover these (once I get some time to finish off the PR).
