SwiftLint crashes always when built with Swift 5 on linux (Ubuntu 16.04 and Ubuntu 18.04).

Complete output when running SwiftLint, including the stack trace and command used

$ swiftlint lint

Environment

SwiftLint version (run swiftlint version to be sure)?
0.31.0
Installation method used (Homebrew, CocoaPods, building from source, etc)?
built from source with Swift 5:

git checkout master
git pull
swift build -c release --static-swift-stdlib

OS: Ubuntu 16.04 and Ubuntu 18.04 (x86_64)

Paste your configuration file:
no file, empty file, ./.build/checkouts/SwiftyTextTable/.swiftlint.yml all same result

included: Source

I've looked at this a bit and it's crashing on this line

SwiftLint/Source/SwiftLintFramework/Extensions/String+SwiftLint.swift

Line 84 in 1d7b37b

    
           if FileManager.default.fileExists(atPath: self, isDirectory: &isDirectoryObjC) {

When self == "". I'm looking into a fix

Oh. This appears to be by-design https://github.com/apple/swift-corelibs-foundation/blob/cae5eaca63cd57f64a93b4d5de87a4ffc04466d5/Foundation/FileManager.swift#L2033

A workaround in the meantime is to pass --path . to lint

keith · 2019-04-03T04:27:11Z

I filed https://bugs.swift.org/browse/SR-10277 since this behavior differs between macOS and Linux

jpsim · 2019-04-06T22:54:46Z

Fixed in #2706. Thanks @keith !

Dschoordsch · 2019-04-08T07:42:28Z
