I started to develop Java in visual studio code but on our legacy project there are hundreds of unused fields. I'm getting 300+ warnings that "The value of the local variable XXXX is not used."
How can I ignore these warnings?

There is a file in the in the project root folder .settings/org.eclipse.jdt.core.prefs.
Add the following line, or edit it if exist:
org.eclipse.jdt.core.compiler.problem.unusedLocal=ignore
UPD: If you want edit more of your preferences, check this link.

Hi, I already found that issue but the thing is I have still different warnings so I need to ignore every warning

Hi again. I removed most of warnings and only TODO's remain atm and this will became solution
Adding onto simply_sideways's answer.
If above settings don't work, you can add "java.settings.url":"/yourPathTo/org.eclipse.jdt.core.prefs" to settings.json file.
Visit https://github.com/redhat-developer/vscode-java/wiki/Settings-Global-Preferences for more settings global preferences.

Not a java expert but following worked for me in vscode
- Open Java Formatter Settings With Preview via vscode command palette
- It should create java-formatter.xml file in the .vscode directory
- Based on previous answers, I added following line to the end of this file
<setting id="org.eclipse.jdt.core.compiler.problem.unusedLocal" value="ignore"/>

Adding onto Vlad's answer for those that come across this question later:
It may be obvious for a more experienced developer but I spent time looking for that .settings folder in a new project, unaware that I could/should just create it myself if it didn't exist. Don't waste your time like me. Create the .settings folder and org.eclipse.jdt.core.prefs file yourself, then add Vlad's code (org.eclipse.jdt.core.compiler.problem.unusedLocal=ignore). That link he gave helped me generalize to other issues.
Also, VS Code may hide a .settings folder that does already exist. To show it, open your settings.json file and add:
"files.exclude": {
"**/.settings": false
}
