Using Groovy to replaceall from backslash to forward

I am having an issue with Groovy replace all. can someone suggest? I wanted to replace \ with /.

String path= 'C:\path\of\my\file' // <- This path comes in dynamic, so I cannot have \\
path = path.replaceAll('\', '/')
println(path)

You could do this:

// If the value is coming in dynamically the `\\` won't
// be in the value, but if you want to represent a \ in source code
// like this it needs to be escaped. 
String path= 'C:\\path\\of\\my\\file'

path = path.replaceAll('\\\\', '/')
println(path)

EDIT:

I have created a runnable example that demonstrates pulling the values in dynamically.

See the project at github.com/jeffbrown/asmescaping.

lib/src/main/resources/info.txt

C:\path\of\my\file
C:\path2\of\my\file
C:\path3\of\my\file

lib/src/main/groovy/asmescaping/SomeClass.groovy

package asmescaping

class SomeClass {

    static void main(String[] args) {
        def inputStream = SomeClass.getResourceAsStream('/info.txt')
        inputStream.eachLine { line ->
            String path = line.replaceAll('\\\\', '/')
            println "Path: $path"
        }
    }
}

That code appears to work:
