如何使用调试信息进行eclipse Luna编译？

Question

I am using java8 with eclipse Luna on Ubuntu. And I checked all the options under

Window->Preferences->Java->Compiler->Classfile Generation

but eclipse still don't generate line number and I can't debug on my own code. Does anybody know another settings somewhere that can fix this problem?

Thanks,

It could be that your project doesn't use the settings from Preferences and has project specific settings instead.

If you right-click on the project and then select "Properties"->"Java Compiler" you can see the line "Enable project specific settings" on the top.

If this checkbox is checked, then you have project specific settings, otherwise the settings from Preferences will be used.
