Command PhaseScriptExecution failed with a nonzero exit code

Reproduction steps

I'm not able to reproduce with the example project here, but here's how I got the error with our project:

1. Generate a project with bazel build mode
2. Build the app
3. Generate again with xcode build mode
4. Build the app

Expected behavior

No error.

Since this file is created based on this check: https://github.com/buildbuddy-io/rules_xcodeproj/blob/main/tools/generator/src/Generator/CreateFilesAndGroups.swift#L600, it would seem there is a bug here, or calling it: https://github.com/buildbuddy-io/rules_xcodeproj/blob/7ee46ec29bb4365f2c81525200a078b80bf5ca4a/tools/generator/src/Generator/AddBazelDependenciesTarget.swift#L5-L19

This only happened to me twice, I'm not able to reproduce it anymore. I'll take a look when I see it again.

[brentleyjones]

@thii Have you run into this since?

[thii]

I have not. Haven't been playing with BwX recently.

[brentleyjones]

I'm going to close this for now then.

[thii]

I've just reproduced it now. Looks like it's an Xcode's bug. Xcode doesn't reload the project if you regenerate it while keeping the project open, so I was building an BwX project with the BwB integration files (which doesn't have create_xcode_overlay.sh).

Seems only happens with large project.pbxproj file.

[brentleyjones]

Ahh, yeah, not sure we can do anything about that. Hopefully people aren't switching modes in the day to day (cc: @erikkerber).
