This issue and issue https://github.com/SlatherOrg/slather/issues/442 and possibly https://github.com/SlatherOrg/slather/issues/441 seems a lot like issue https://github.com/SlatherOrg/slather/issues/243 which PR https://github.com/SlatherOrg/slather/pull/414 fixed long time ago. I suspect there's a change in MacOS Catalina which throws an error different from Errno::E2BIG (Edit: This seems unlikely). It might also be a completely different problem, but it's difficult to say without more info.

We're encountering the same issue since about two months on one of our projects, for some builds only (but reproducible with these builds).

PR #414 actually catches the E2BIG error in most cases (I’ve seen it split the command line in two for other projects/branches), but in these specific cases, the error is not caught. But we still end up with the same /usr/bin/xcrun: Argument list too long message. So I also suspect another error than E2BIG to be thrown.

Note that in these cases, the total length of "xcrun llvm-cov" + llvm_cov_args + source_files is less than ARG_MAX (262144 bytes for Catalina), even if I add the 1802 bytes of env vars (I read they could count in ARG_MAX). And AFAIK, we have no filenames with non-latin characters that could use more than 1 byte.

Hello, I am facing the same problem on one of my code coverage calculation. I've performed the unit test in fastlane with scan (calling them all from Jenkins) and then I am using slather to get the code coverage in llcov format. This is the command and the following output:

slather coverage --jenkins --llvm-cov --build-directory ./DerivedData --binary-basename 'My App Mobile' --output-directory ./sonar-reports --scheme MYA_UAT --workspace MyApp.xcworkspace MyApp.xcodeproj /Users/vobadm/.rvm/gems/ruby-2.4.2/gems/slather-2.4.7/lib/slather.rb:26: warning: Insecure world writable dir /change in PATH, mode 040777 Slathering... sh: /usr/bin/xcrun: Argument list too long Slathered

Is there a way to get through this?

I am having the same error, we are integrating it with sonar but even running manually it shows the same error:

And nope. Above doesn't fix it either 😵
