Dart pub工具的返回码是什么？ [英] What are the return codes for the Dart pub tool

问题描述

我将在批处理文件中迭代地启动pub get和pub build，我需要测试错误的返回码。返回代码似乎没有记录在Dart文档中。

I'm going to be launching "pub get" and "pub build" iteratively in a batch file, and I need to test the return codes for errors. The return codes don't seem to be documented in the Dart docs. Does anyone know what they are, or where they're documented?

推荐答案

我发现这些：

• 搜索
  
• 在此处定义常量值，可以使用exit_codes的_internal / pub / bin / pub.dartrel =nofollow> pub.dart ：（复制自 exit_codes.dart ）

• search in pub.dart for 'exit_codes' to see which constants are used
• the constant values are defined here: (copied from exit_codes.dart)

library pub.exit_codes;

/// The command completely successfully.
const SUCCESS = 0;

/// The command was used incorrectly.
const USAGE = 64;

/// The input data was incorrect.
const DATA = 65;

/// An input file did not exist or was unreadable.
const NO_INPUT = 66;

/// The user specified did not exist.
const NO_USER = 67;

/// The host specified did not exist.
const NO_HOST = 68;

/// A service is unavailable.
const UNAVAILABLE = 69;

/// An internal software error has been detected.
const SOFTWARE = 70;

/// An operating system error has been detected.
const OS = 71;

/// Some system file did not exist or was unreadable.
const OS_FILE = 72;

/// A user-specified output file cannot be created.
const CANT_CREATE = 73;

/// An error occurred while doing I/O on some file.
const IO = 74;

/// Temporary failure, indicating something that is not really an error.
const TEMP_FAIL = 75;

/// The remote system returned something invalid during a protocol exchange.
const PROTOCOL = 76;

/// The user did not have sufficient permissions.
const NO_PERM = 77;

/// Something was unconfigured or mis-configured.
const CONFIG = 78;
