我正在尝试使用 ant 构建我的 android 项目(它在 eclipse 中运行良好)。我在以下构建失败行中运行错误:
BUILD FAILED
.../android_sdks/tools/ant/build.xml:680: The following error occurred while executing this line:
.../android_sdks/tools/ant/build.xml:693: Compile failed; see the compiler error output for details.
上面的java编译有很多错误，都是cannot find symbol错误。大多数这些符号是添加到 R 文件中的变量。有些是项目中的类。
我使用以下方法设置构建环境:
android update project --path .
我的工具和 platform_tools 都是最新的，我在 android-7 上运行。我刷新了项目，对项目进行了清理，甚至重新启动了 Eclipse。
我对 ant 还很陌生，如果有任何建议，我将不胜感激。
构建失败的输出(根据要求，对于格式问题，我深表歉意):

最佳答案
想通了:
我在 Eclipse 上排除了构建路径中的文件。显然，Ant 的情况并非如此。我没有在我的 Ant 文件中添加这么多文件，而是删除了这些文件，然后一切都解决了。
