Is it possible for the Jenkins pipeline function fileExist to handle wildcards

Question

Can Jenkins pipeline function fileExist handle wildcards? I have created a zip file in the workspace folder in advance.

Answer 1

The fileExist step does not accept wildcards.

But, if you use the ‘Pipeline Utility Steps Plugin’, you can make use of the findFiles function which accepts wildcards.

An example:

def files = findFiles glob: '**/*.zip'
boolean exists = files.length > 0

Answer 2

If you do not have the plug-in, you can use the shell "find". 

def exitCode = sh script: 'find -name "*.zip" | egrep .', returnStatus: true boolean exists = exitCode == 0

Answer 3

FileExists() does not support wildcards. FileFindFirst() does though, and you can check for a folder that way.
