Update #1: All these annotations are still valid in Eclipse 3.4 and 3.5, there have been no new SuppressWarning arguments added in those versions of the JDT compiler.

If you are a Java developer and use the new @SuppressWarnings annotation in your code from time-to-time to suppress compiler warnings you, like me, have wondered probably about a million times already just exactly what are the supported values that can be used with this annotation.

The reason the list isn’t easy to find is because it’s compiler specific, which means Sun may have a different set of supported values than say IBM, GCJ or Apache Harmony.

Fortunately for us, the Eclipse folks have documented the values they support (As of Eclipse 3.3), here they are for reference:

all to suppress all warnings
boxing to suppress warnings relative to boxing/unboxing operations
cast to suppress warnings relative to cast operations
dep-ann to suppress warnings relative to deprecated annotation
deprecation to suppress warnings relative to deprecation
fallthrough to suppress warnings relative to missing breaks in switch statements
finally to suppress warnings relative to finally block that don’t return
hiding to suppress warnings relative to locals that hide variable
incomplete-switch to suppress warnings relative to missing entries in a switch statement (enum case)
nls to suppress warnings relative to non-nls string literals
null to suppress warnings relative to null analysis
rawtypes to suppress warnings relative to un-specific types when using generics on class params
restriction to suppress warnings relative to usage of discouraged or forbidden references
serial to suppress warnings relative to missing serialVersionUID field for a serializable class
static-access to suppress warnings relative to incorrect static access
synthetic-access to suppress warnings relative to unoptimized access from inner classes
unchecked to suppress warnings relative to unchecked operations
unqualified-field-access to suppress warnings relative to field access unqualified
unused to suppress warnings relative to unused code
