<javac srcdir="src" 
   destdir="build/classes" source="1.6" 
   target="1.6" debug="true" encoding="Cp1252"
   nowarn="true">

但它仍然在输出中引发编译器警告：

[javac] Compiling 73 source files to C:\IKOfficeRoot\Java\ERP\Framework\build\classes

[javac] C:\IKOfficeRoot\Java\ERP\Framework\src\de\ikoffice\util\LoggerFactory.java:49: warning: sun.reflect.Reflection is Sun proprietary API and may be removed in a future release

我也试过

<compilerarg line="-Xlint:-unchecked -Xlint:-deprecation"/>

和

<compilerarg value="-Xlint:none"/>

但这也没有效果.如何清除警告？
