Ant exec:重定向标准输出但不是标准错误 [英] Ant exec: redirecting standard out but not standard error

问题描述

我有一个 exec 任务，我使用 outputproperty 属性将其输出放入一个属性中.该命令可能会向 stderr 打印一些错误，我不希望将这些错误包含在输出中(因为输出被馈送到另一个命令中)，而是要打印给用户.所以我将输出和错误重定向到单独的属性和 echo 错误属性.不得不 echo 错误似乎有点麻烦.是否可以重定向 exec 的输出但在 stderr 或 stdout 上留下错误?我认为这意味着将 error 属性设置为某个神奇的值，但我无法弄清楚该值是什么.

I have an exec task whose output I am putting into a property using the outputproperty attribute. The command may print some errors to stderr, I do not want the errors to be included in the output (since the output is being fed into another command) but rather to be printed out to the user. So I am redirecting the output and error into separate properties and echo the error property. It seems kind of a hack to have to echo the error. Is it possible to redirect the output of an exec but leave error on stderr or stdout? I assume it means setting the error attribute to some magical value but I cannot figure out what that value is.

推荐答案

尝试移除 error 或 errorproperty 属性并添加 logError="true".

Try removing error or errorproperty attributes and adding logError="true".
