然后，您使用条件型if语句，以检查该命令的返回代码。
Many similar tasks must be scripted separately because ant lacks support for loops, inheritance, and conditional processing; therefore, build code is duplicated and is sometimes redundant.
很多类似任务必须单独编写脚本，因为Ant缺乏对循环、继承和条件处理的支持；因而构建代码将出现重复，以致产生冗余代码。
This little piece of code shows the conditional if statement.
这一小段代码显示了条件型if语句。
You can code conditional WebSphere TX map logic within map rules using the PRESENT function, which tests to see if a particular data object is found in a data structure.
可以在映射规则中使用present函数编写有条件的WebSphereTX映射逻辑，这个函数检查在数据结构中是否可以找到某个数据对象。
For example, if the conditional is marked "likely" then the compiler can place the True portion of the code immediately following the branch (which will not be taken).
例如，如果一个条件标上了“likely”，那么编译器可以把代码的True部分直接放在分支指令后面(这样就不需要执行分支指令)。
I don't need to write custom tasks, for instance, because a Rake build script is Ruby (as opposed to XML); therefore, if I need some conditional logic, I can easily code it where I need it.
例如，我不必编写定制任务，因为Rake构建脚本是Ruby(而不是XML)；因此，如果我需要某种条件逻辑，那么很容易在需要的地方编写这种逻辑。
You have a date field, a postal code, a field whose input is conditional upon the content of another, and so on.
