How to disable the "Optional used as field or parameter type" warning in IntelliJ?
提问by Andrey
Jetbrains has recently decided that java.util.Optional(as well as Guava's com.google.common.base.Optional) shouldn't be used as field or parameter type... thanks, but no thanks... How can this warning be disabled?
Jetbrains 最近决定java.util.Optional（以及 Guava 的com.google.common.base.Optional）不应该用作字段或参数类型......谢谢，但不，谢谢......这个警告怎么可能被禁用？
As a side note: triggering warnings on this specific usage of Optional seems completely unjustified...
附带说明：在 Optional 的这种特定用法上触发警告似乎完全没有道理......
