You can use a JDK 1.5 annotation to suppress PMD warnings, like this:
// This will suppress all the PMD warnings in this class @SuppressWarnings("") public class Bar { void bar() { int foo; } }
Alternatively, you can tell PMD to ignore a specific line by using the "NOPMD" marker, like this:
public class Bar { // 'bar' is accessed by a native method, so we want to suppress warnings for it private int bar; //NOPMD }
You can use whatever text string you want to suppress warnings, for example, here's how to use TURN_OFF_WARNINGS as the suppressor:
$ cat Foo.java public class Foo { void bar() { int x = 2; // TURN_OFF_WARNINGS } } $ ./pmd.sh Foo.java text unusedcode -excludemarker TURN_OFF_WARNINGS No problems found! UnusedLocalVariable rule violation suppressed by //NOPMD in /home/tom/pmd/pmd/bin/Foo.java
Note that PMD expects the //NOPMD marker to be on the same line as the violation. So, for example, if you want to suppress an "empty if statement" warning, you'll need to place it on the line containing the "if" keyword, e.g.:
$ cat ~/tmp/Foo.java public class Foo { void bar() { int x = 42; if (x > 5) { // NOPMD } } } $ java net.sourceforge.pmd.PMD ~/tmp/Foo.java text basic No problems found! $
