How can I disable compiler warnings in Eclipse on a file specific basis?

Question

In my Eclipse project are a handful of generated .java files that I need to use for SQLJ and I can't move to a separate project (due to Administrative Overhead). These files are also regularly regenerated so editing them is unfortunately out.

Unfortunately these files generate a few hundred java compiler warnings which drown out the useful warnings I get on files that I actually can edit.

Is there any way in Eclipse to say Ignore all the warnings of a file-by-file basis? Or can I block out a specific sub-directory?

Answer 1

One way to do this is to add @SuppressWarning(...) annotations to the source code.

Another way would be to move the troublesome code to a separate Eclipse project and use per-project compiler settings.

EDIT

Surely, you can partition your code into multiple projects with the appropriate inter-project dependencies?

If not, I'd say you are out of realistic options. (But if you want some unrealistic ones, you could post-process the generated code to add the annotations, hack the Eclipse Java compiler to implement per-file suppression, hack the Eclipse "Problems" view to implement per-file/directory filtering of errors, etc, etc.)

Answer 2

@SuppressWarning annotation?

Per, Stephen's comment, you can find the "Per project compiler settings option here"

Project->Properties->Java Compiler->Errors/Warnings

Enable project specific settings

Answer 3

The "problems" view in eclipse can be filtered; I always have it set to "on selected element and its children only". Granted, this is more of a work-around, but it lessens the impact of having the files in the same project. (Note that even if you must have them in the same project, you can keep them in a separate source folder).
