问题描述
好像xcodebuild将所有内容都打印到stdout.
Seems like xcodebuild prints everything to stdout.
$ /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project test.xcodeproj build -target test -configuration Debug -jobs 3 2>err
# xcodebuild stdout with bunch of warnings and errors
$ cat err
** BUILD FAILED **
The following build commands failed:
CompileC _build/test.build/Objects-normal/x86_64/test.o /Users/me/test/test.cpp normal x86_64 objective-c++ com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)
那不能让我的IDE(QtCreator)正确解析输出.
That doesn't let my IDE(QtCreator) correctly parse the output.
实际上，clang将错误和警告打印到stderr.但是xcodebuild出于某种原因将所有内容重定向到strdout.除了 1&& 2 之外，是否有办法使xcodebuild向stderr打印错误和警告?
And clang, actually, prints errors and warnings to stderr. But xcodebuild redirects everything to strdout for some reason. Is there a way to make xcodebuild print errors and warnings to stderr except 1>&2?
推荐答案
是否可以尝试使用-quiet选项运行命令，如下所示.
Can you try running the command with -quiet option as follows.
# Do not print any output except for warnings and errors
/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project -quiet
因此，您可以仅使用-quiet选项传递警告和错误，并且可以使用 2>仅过滤错误../errors.log
So you can just pipe warnings and errors by using -quiet option and to filter only error you can use 2> ./errors.log
/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project -quiet test.xcodeproj build -target test -configuration Debug -jobs 3 2> ./errors.log
还有其他检查工具，例如 xcpretty 和 xcbeautify .
There are other tools to check such as xcpretty and xcbeautify.
