Hi:

When I run ant, a lot of warnings are printed out on the screen. It is very=
 daunting. It makes new people to feel, as first response, this is broken. =
But actually, the build is successful. I pasted a few warning messages belo=
w. In our real code, there are hundreds of them.

    [javac] /abc/efg/MyTools.java:125: warning: [unchecked] unchecked call =
to add(E) as a member of the raw type java.util.List
    [javac]             recursiveDirectoriesToBuild.add(workingDir);
    [javac]                             ^
    [javac] /abc/efg/MyTools.java:212: warning: [unchecked] unchecked call =
to Vector(java.util.Collection<? extends E>) as a member of the raw type ja=
va.util.Vector
    [javac]             return new Vector(v2);
....

I know one solution, the basic solution, is to going to the code and use Ja=
va Annotation feature to add "Ignore Warning etc" at those places. But ther=
e are so many places and the code were written by different people. We don'=
t want to modify the code! I am wondering if ant has a feature to turn off =
the warning messages.=20

This is my ant script to build:
	<target name=3D"compile" depends=3D"prepare">
		<javac srcdir=3D"${src.dir}" destdir=3D"${build.dir}" compiler=3D"modern"=
 fork=3D"yes" debug=3D"on">
			<classpath refid=3D"project.classpath"/>
			<compilerarg value=3D"-Xlint"/>
		</javac>
	</target>

To be honest, I do not know the feature "-Xlint" etc.

Thank you very much.
