我在Android项目中导入了 aspectjtools.jar ，但是当我运行项目时（无论我是否在代码中使用.jar），eclipse都会显示以下警告：
[2012-03-05 16:34:20 - AndroidExample] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.aspectj.ajdt.internal.compiler.CompilerAdapter$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

在多次显示相同的警告后，Eclipse停止工作，我必须重新启动它。
我尝试使用Maven，但它显示了相同的警告，并在显示警告1分钟后，项目编译但不能正常工作。
如何解决这个问题？
