Groovy in Active Choice Parameter

Question

I have the following groovy cod to display in Active Choice Parameter some folder names and if the folder contains the ".a7" file display the file, if not,should post a error message. My problem is that my cod don't display the error message if the folder "a7.nativ" is missing and implicit the path to ".a7" file(/mnt/a7/v5.5/a7.nativ/v5.5/55.a7) is interrupted. Can somebody help me please? This is the cod:

 Build=[] path2 = "/mnt/cc7/v5.5/a7.nativ/v5.5/" new File(path2).eachFileMatch(~/.*.a7/) { Build.add(it.getName()) } if(Build){ return Build } else { return ["There is no file to display"] }

You need an additional step that checks if given path exists. Otherwise, you implicitly assume that the given folder always exists. Consider the following modification:

def build = [] def path2 = "/mnt/cc7/v5.5/a7.nativ/v5.5/" def file = new File(path2) if (!file.exists()) { return ["There is no file to display"] } file.eachFileMatch(~/.*.a7/) { build.add(it.getName()) } return build ?: ["There is no file to display"]
