Xcode5 xcodebuild failed when the precompile header includes Pods-environment.h and execute pod install before xcodebuild

Question

Simplified version of build script is:

# change Podfild here 
pod install
xcodebuild

It works with Xcode 4.6, but with Xcode5-DP5 it failed.

fatal error: file '/path/to/myproject/Pods/Pods-environment.h' has been modified
  since the precompiled header
  '/Users/hiroshi/Library/Developer/Xcode/DerivedData/MyProject-gfmuvpipjscewkdnqacgumhfarrd/Build/Intermediates/PrecompiledHeaders/MyProject-Prefix-dwjpvcnrlaydzmegejmcvrtcfkpf/MyProject-Prefix.pch.pch'
  was built

Answer 1

It succeeded after changed buildactions like this.

# change Podfild here 
pod install
xcodebuild clean build

I guess Xcode5 won't re-precompile the precompile header only the default build buildaciton, need to do clean first.
