我曾试图用生成的项目来构建apk，但我不断地得到错误。我一直在使用ant clean debug来创建，但我不断遇到错误，因为它无法找到我检查过的build-extras.xml，而build-extras位于以下路径：

C:\Users\svond_000\Documents\dalvik-sdk-8u40-ea3\dalvik-sdk\android-tools\build-extras.xml

那么如何用javafxports和android和ant构建apk呢？
这是我的命令日志，如果有帮助的话：

C:\Users\svond_000\Documents\dalvik-sdk-8u40-ea3\dalvik-sdk\samples\Ensemble8\android\Ensemble8Android>ant clean debug
