Failed to generate code with SwiftTemplate with (at least) custom build path / custom cache path

[pavel-trafimuk]

After updating up to 2.2.5 my ymls with swifttemplate start failing.
Sourcery argument:
--config tools/sourcery/generated/phase_02/Settings/SettingsContainer.yml -v -p --cacheBasePath tools/sourcery/customCache --buildPath tools/sourcery/customSwiftTemplateBuilds/5811391726280627442

Error:

After quick investigation,
code if FileManager.default.fileExists(atPath: originalBinaryPath.string) { doesn't work correctly,

(lldb) po originalBinaryPath.string
"/Users/pavel.trafimuk/Developer/Viber_iOS_2/tools/sourcery/customSwiftTemplateBuilds/5811391726280627442/SwiftTemplate/71EA0DA5-E3EF-4AAC-998C-3EC9A3B9B5BF/2.2.5/MI6b0Z6LKDJ0eIbHkx7BmAltVogLlLDJK%2FKJLgPAPLY%3D"

But symlink exists

[pavel-trafimuk]

Updated, got it, FileManager resolves symlink before checking of file existing, so symlink is broken, after checking it I found that yes, seems like I reproduce issue #1321 cause destinationBinaryPath = cachePath + hashPath based on cachedPath which is relative

probable quick fix, wdyt @art-divin

If it works in your case, it shouldn also in others'!

So much thanks, very appreciated 🙌🏻👏 - you contribution.
