tests/android_tests/gradlew.bat is dirty in every fresh clone (*.bat text eol=crlf vs LF blob) — breaks rive-ios SPM submodule resolution in Xcode #120

Summary

tests/android_tests/gradlew.bat shows as modified in every fresh clone of this repo. The root .gitattributes declares *.bat text eol=crlf, but the blob is stored LF-normalized — with that combination, git writes CRLF into the working tree at checkout and immediately reports the path as dirty ("warning: in the working copy of 'tests/android_tests/gradlew.bat', LF will be replaced by CRLF the next time Git touches it").

Repro

$ git clone https://github.com/rive-app/rive-runtime && cd rive-runtime
$ git status --porcelain
 M tests/android_tests/gradlew.bat

Minimal isolated repro of the mechanism (git 2.50.1):

$ git init repo && cd repo
$ printf '*.bat text eol=crlf\n' > .gitattributes
$ printf '@rem\n@rem test\n' > gradlew.bat        # LF endings, like the committed blob
$ git add -A && git commit -m init
$ cd .. && git clone repo clone && git -C clone status --porcelain
 M gradlew.bat

Note git add --renormalize stages nothing (the blob is already LF), so the dirt can't be cleaned up by renormalizing — every clone is dirty by construction until the attribute changes.

Why it matters downstream

rive-ios embeds this repo as a git submodule, and Swift Package Manager clones it into Xcode's DerivedData/.../SourcePackages/checkouts/. The perpetually-dirty submodule breaks SPM package resolution — Xcode surfaces it as "Failed to analyze workspace", and a rive-ios version bump fails to resolve until the checkout is manually repaired. (Observed with rive-ios 6.22.0, Xcode 26.x.)

Suggested fix

Exempt the wrapper script from text normalization so the working tree is byte-identical to the blob, e.g. in .gitattributes:

tests/android_tests/gradlew.bat -text

(Optionally re-commit the file with CRLF endings at the same time if CRLF-on-disk is desired for Windows — with -text git no longer converts either way. gradle init's own generated .gitattributes handles it this way.)

Workaround for consumers

Add the override to a global attributes file so all checkouts (including SPM's) stay clean:

$ printf 'tests/android_tests/gradlew.bat -text\n' >> ~/.config/git/attributes
