Suppress unchecked warnings in ant

Question

Hi there,
I wish to suppress warnings such as these in my ant build;
[javac] Note: Some input files use unchecked or unsafe operations.
[javac] Note: Recompile with -Xlint:unchecked for details.Going on what the javac ant task allows and what javac itself says to do I think I should have something like;
<javac srcdir="${srcDir}" destdir="${classDir}">
     <!-- This is only allowed for the srcDir.  Do not do this anywhere else -->
     <compilerarg line="-Xlint:"-unchecked""/>
</javac>But this doesn't appear to do what I want. Anyone know exactly how to get these warnings suppressed?

Answer 1

Hers's an example (just compile on command line);
import java.util.ArrayList;
public class CompilerTest
public static void main(String args[])
ArrayList list = new ArrayList();
list.add("John");
System.out.println("Element in list: "+list.get(0));
}Compiling with;
1. Ordinary compilation
javac CompilerTest.java
Note: CompilerTest.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.2. -Xlint:unchecked
javac -Xlint:unchecked CompilerTest.java
CompilerTest.java:22: warning: [unchecked] unchecked call to add(E) as a member
of the raw type java.util.ArrayList
list.add("John");

1 warningI want something which does the opposite of this (i.e. doesn't warn me at all about unchecked warnings.
3. -Xlint:-unchecked (this is what the compiler help tells me to do, see the non-standard options section on
http://java.sun.com/javase/6/docs/technotes/tools/windows/javac.html#options)
javac -Xlint:-unchecked CompilerTest.java
Note: CompilerTest.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
