xcode build error

I haven't touched iphone development for one year. Today I have to update my app which has some problem on iphone OS 4.x, however I got a mystery when I rebuilt the project after renewing the iphone development certificate.

Command /bin/sh failed with exit code 1
Justis Publishing Ltd:no such identity Line Location Tool:0



I have to admit that I did try this code sign certificate(Justis Publishing Ltd) last year before I opened an account with Apple (costed $99), and this cert was expired, so I deleted it in Keychain.

I am quite sure I chose the correct development certificate which was downloaded from my account on iphone development portal. In XCode IDE, I poked around every corner, but failed to get rid of this error.


My gut feeling told me this problem lied in the project setting, so I decided to have a look with the Terminal.

First of all, I went to the project setting folder(the ".xcodeproj" actually is a folder).

grep -i "Justis" *.*

The above grep command result said the string "Justis" did exist in the file project.pbxproj!

With nano, I saw the following in this file

/* Begin PBXShellScriptBuildPhase section */
3F3B364F0FD01DF6001754F2 /* ShellScript */ = {
isa = PBXShellScriptBuildPhase;
buildActionMask = 2147483647;
files = (
);
inputPaths = (
);
outputPaths = (
);
runOnlyForDeploymentPostprocessing = 0;
shellPath = /bin/sh;
shellScript = "if [ \"${PLATFORM_NAME}\" == \"iphoneos\" ]; then\nplatform=/Developer/Platforms/iPhoneOS.platform\nallocate=${platform}/Developer/usr/bin/codesign_allocate\nexport CODESIGN_ALLOCATE=${allocate}\ncodesign -fs \"Justis Publishing Ltd\" \"${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}\"\nfi\n";
};
/* End PBXShellScriptBuildPhase section */

I have no idea how and when I added this section to this project, but I think I don't need this section at all, so I deleted it and saved the file, then reopened Xcode, and rebuilt my project, Bingo! I got everything right!

Like all other IDE, Xcode is not omnipotent. Sometime, you have to look into Makefile(here the project.pbxproj file), isn't it?
