我有一个曾经用ant构建的Android项目，但是现在不再构建。
问题是我的build.xml中包含的某些jar文件在当前的AndroidSdk中不再存在：
$ ant -v
[...]
dropping /.../AndroidSdk/tools/lib/anttasks.jar from path as it doesn't exist
dropping /.../AndroidSdk/tools/lib/sdklib.jar from path as it doesn't exist
dropping /.../AndroidSdk/tools/lib/androidprefs.jar from path as it doesn't exist
[...]
build.xml:46: taskdef class com.android.ant.SetupTask cannot be found
哪个是包含这些文件的最新Android SDK？
