在我的项目中，我使用ant来构建我的apk包。每次升级我的android sdk后，我都必须调整我的构建脚本。谁能告诉我如何找到更改文件？
这是我的问题：第一次构建：控制台引发错误：
BUILD FAILED
build.xml:140: Missing attribute renderscriptSupportOutOut
错误脚本位置是：
<dependency
libraryFolderPathOut="project.library.folder.path"
libraryPackagesOut="project.library.packages"
libraryManifestFilePathOut="project.library.manifest.file.path"
libraryResFolderPathOut="project.library.res.folder.path"
libraryBinAidlFolderPathOut="project.library.bin.aidl.folder.path"
libraryNativeFolderPathOut="project.library.native.folder.path"
libraryRFilePathOut="project.library.rfile.path"
jarLibraryPathOut="project.all.jars.path"
buildToolsFolder="${sdk.dir}/build-tools"
targetApi="15"
verbose="${verbose}" />
第二次构建，添加“renderscriptSupportOutOut”属性后，控制台引发错误：
BUILD FAILED
build.xml:140: dependency doesn't support the "renderscriptSupportOutOut" attribute
这是我的 buid.xml 部分：
