请提供带有堆栈跟踪的完整 ant 输出.您可能使用了不匹配的 sdk/目标平台版本.这可能会导致使用 build.xml 中不受支持的构建系统功能.升级您的 sdk，并使用 android 工具更新构建配置:

Please, provide full ant output with stack trace. You're probably using mismatched sdk/target platform versions. This might cause use of unsupported build system features from your build.xml. Upgrade your sdk, and update build configuration with android tool:

android update project --name --target --path
