How to abort build if run script phase gives an error
提问by GorillaPatch
I would like to use a run scripts target to tag my revision in mercurial and upload it to a server. I created a new run scripts target that depends on the other target building my app, then I added two run script phases directly one after another.
我想使用运行脚本目标在 mercurial 中标记我的修订并将其上传到服务器。我创建了一个新的运行脚本目标，它依赖于构建我的应用程序的另一个目标，然后我一个接一个地直接添加了两个运行脚本阶段。
Now my question: how can I prevent executing run script phase #2 if run script phase #1 gives an error (return code of script is unequal 0)?
现在我的问题是：如果运行脚本阶段 #1 出现错误（脚本的返回代码不等于 0），我该如何阻止执行运行脚本阶段 #2？
The second script would upload the files to a server, so I only want to execute this phase if everything went right until then.
第二个脚本将文件上传到服务器，所以我只想在一切顺利的情况下执行这个阶段。

A solution would be to generally stop building when errors occur:
解决方案通常是在发生错误时停止构建：
XCode -> Preferences -> Building -> Build options "Continue building after errors".
XCode -> 首选项 -> 构建 -> 构建选项“错误后继续构建”。
If you uncheck that, the build will stop if your script returns something unequal 0 and the second script will not be executed. If you use xcodebuild, the name for the setting is "PBXBuildsContinueAfterErrors".
如果取消选中，如果您的脚本返回不等于 0 的值，则构建将停止，并且不会执行第二个脚本。如果您使用 xcodebuild，则该设置的名称为“PBXBuildsContinueAfterErrors”。

Your first script can abort the build with "exit 1", like this:
您的第一个脚本可以使用“exit 1”中止构建，如下所示：
if [ error ] then
echo "There are some errors, etc..."
exit 1
fi

exit(1)does the job for me. Adding an echo "error:will flag it up as an error within Xcode.
exit(1)为我做这项工作。添加一个echo "error:将在 Xcode 中将其标记为错误。
echo "error: Everything has failed!"
exit 1
