Regarding eclipse Kepler SR1
Hi,
I remember that a unused private methods were getting a warning from the compiler.
I don't know if it's changed switching to Kepler (or a previous release) or if it is project settings, because I'm working on a new project where the eclipse settings are shared.
I even couldn't find the setting in the eclipse compiler settings.
回答1:
go to your project on "Package Explorer", right-click on it and choose "properties". Then inside properties "Java Compiler", "Errors/Warnings". Check the box with "Enable project specific settings". Scroll down to the section where it says "Unnecessary code" and check them to "Warning"
回答2:
The setting is Preferences > Java > Compiler > Errors/Warnings > Unnecessary code > Unused private member.
回答3:
Go to
Windows --> Preferences --> Java --> Compiler --> Errors/Warnings
Under Unnecessary Code section you can find Unused private member
Change it to Warning
回答4:
It could be your company/ project uses other eclipse plugins which allow code analysis with lets say sonar and the eclipse static code analysis thatfore has been fully disabled.
I am still using the Indigo version of eclipse but i assume you can see what youre looking for under Window->Preferences->Java->Compiler->Errors/Warnings

Change settings from preferences. Here is some illustration.
