Is it normal for Xcode not to detect if a pre-action failed?

I am using Xcode 4 and I added an preaction to the run scheme, a bash script, but it seems that Xcode is i开发者_如何学JAVAgnoring the exit status of the script and always run, even if the exit code is not zero.

Is this normal? What alternatives do I have for adding a custom step, one that can fail?

Update: I also tried exit 1 for post-action for build but with the same results, always executing without any feedback.

How can I make a custom step that can mark the build as failed?

Not only does it not seem to care about pre-/post-action script exit status, but it doesn't seem to place the output into the build/run logs either. There are I think two separate threads about this buried in Apple's Xcode 4 dev forums. No word on whether this is a bug or a feature.

You can add something like kill $PPID in the run script phase to terminate the xcodebuild (with exit code 70).

When using Xcode, kill $PPID is not a solution, as I was commenting to Farcaller.

My solution is to have the pre-action script generate a header file (e.g. SchemePreActions.h) and make it empty for normal situation, and include it into your code (e.g. into AppDelegate.m).

This way, if you want the pre-actions script to report an error, put there a #error line, like in this real-world example:

if [ $CONFIGURATION == Debug ]; then
    echo "#error AppStore builds must not be in debug configuration" >> SchemePreActions.h
fi

Xcode will report this error very nicely.

It is recommended to have the generated file ignored by git.

As a tip I will add that my pre-actions script always starts with these lines:

echo "//auto-generated. no need to commit"      > SchemePreActions.h
echo "#define SCHEME_${SCHEME_NAME}"            >> SchemePreActions.h
echo "#define SCHEME_NAME @\"${SCHEME_NAME}\""  >> SchemePreActions.h
if [[ ${SCHEME_NAME} =~ "_PROD" ]]; then
    echo "#define PRODUCTION"                   >> SchemePreActions.h
fi

This way, by including SchemePreActions.h, my code can test to see if running under a specific scheme.
