Question
Why Are Compile-time Warnings Suppressed?
Answer
You’ll Notice That ‘build.gradle’ Includes The Following Line? This tells Gradle to suppress all warnings during compilation. The reason for this is that the framework currently has many warnings, most of which are related to generics usage - particularly raw type warnings - e.g. using Class instead of Class<?> This is an artifact switching to Java 5 in Spring 3. As with the Javadoc warnings mentioned above, committers are encouraged to fix these warnings whenever possible. Once the bulk of them are eliminated, we can switch to -Xlint: all. In the meantime, it just creates unnecessary noise in the build output.
