How to suppress a warning
To suppress a warning, use the @SupressWarnings annotation as shown below:

// This will suppress all the PMD warnings in this class
@SuppressWarnings("PMD")
public class Bar {
void bar() {
  int foo;
}
}// This will suppress UnusedLocalVariable warnings in this class
@SuppressWarnings("PMD.UnusedLocalVariable")
public class Bar {
void bar() {
  int foo;
}
}
Or add the comment //NOPMD to the line where the violation is happening. See below an example of how to suppress an "empty if" warning.

public class Foo {
void bar() {
  int x = 42;
  if (x > 5) { // NOPMD
  }
}
}

How to improve rules or report false positives
Please report to OpenCloud using the form below any improvement you think it can be made to particular rules and false positives that are annoying you.

If you are an advanced user, the source code of the rules is available on the public source code repository here. Please check out the source code, modify and build your own rules jar, and contribute the changes back!
