I get an error saying unknown annotation when I use the @testVisible KW in my class, when using the force.com IDE, however it works fine in the developer console.

Is there a bug? do I need to update the version of my IDE? I know that this annotation came out last year...https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_classes_annotation_testvisible.htm

Eclipse IDE for Java Developers

Version: Helios Service Release 2 Build id: 20110218-0911

Force.com IDE

Version: Summer '13 (28.0.1)

  • Is there any reason why you aren't keeping your IDE up to date?

You need to updated the IDE and force.com plugin. Older version of IDE does not recognize the latest keywords and throws error
