OSX/Bash - 检测构建失败

Question

直接从bash使用Xcodebuild,如何检测失败？无论如何,退出代码始终为0.我意识到有一个"FAILED"或"SUCCEEDED"纹理输出,但是不是更优雅的方式吗？

此外,我有时使用"make"(尤其是我的基于Qt的版本).有没有办法从构建脚本中检测make失败？

Answer 1

即使构建失败,xcodebuild也总是返回0.要检测错误,您可以使用如下脚本:

build_errors_file=build_errors.log

# Pipe errors to file
xcodebuild 2>$build_errors_file

errors=`grep -wc "The following build commands failed" $build_errors_file`
if [ "$errors" != "0" ]
then
    echo "BUILD FAILED. Error Log:"
    cat $build_errors_file
    rm $build_errors_file
    exit 1
fi
rm $build_errors_file

# ... continue

我确认在使用archive选项运行xcodebuild时不会打印**BUILD FAILED**,所以看起来要查找的字符串是'以下构建命令失败'.

也许这取决于 Xcode 的版本或者可能是如何失败的。这是我检查 $? 时得到的结果 找不到某些包含文件后：

...
/Users/davidb/Source/icanvas/iCanvas-project/iCanvas-target/iPhone/ConversationViewController.m:21:9: fatal error: 'CanvasKit/CKActionSheetWithBlocks.h' file not found

        ^

** BUILD FAILED **
