Describe the bug
yarn install fails on windows machine for the same dependency.
Doing yarn install on mac you get the following file inside the cache test-github-dependency-git+ssh-298a2e1cf5-17a50be342.zip
On windows it fails with:
yarn install

b-dependency.git#commit=a9558b728dfcee08264f221211d859e3417a4971: The remote arc
hive doesn't match the expected checksum
➤ YN0000: └ Completed in 7s 544ms
➤ YN0000: Failed with errors in 7s 559ms
If i change the .yarnrc.yml with checksumBehavior: update then windows generates: test-github-dependency-git+ssh-298a2e1cf5-a5121ebaf2.zip. You can see that the checksum is different (17a50be342 vs a5121ebaf2 )
Doing an hexdump for both of files and comparing ( hexdump -C test-github-dependency-git+ssh-298a2e1cf5-17a50be342.zip):

The difference is some small character, after more investigating the issue is coming from the bash script gradlew that lives inside the dependency. If i remove that gradlew file, the issue is not longer reproducible
To reproduce
git clone https://github.com/angel-git/yarn-issue
cd yarn-issue
yarn install
do the same on windows machine

Research direction
Clone the linked yarn-issue reproduction and run yarn install on macOS and Windows with the default checksum behavior. Compare the generated cache archives, then inspect how the gradlew file is handled during fetching; done means the same dependency produces a matching checksum across both platforms.
