[SOLVED] How do I extract a specific number from a string / url using groovy?

How do I extract a specific number from a string / url using groovy?

I am trying to extract a specific number(without any special characters) from a url/string using groovy script.

ABC/MyABC/XYZ/POC-xyz-api-oci #89

In the above string, I want to extract only the number 89 without any special characters using groovy script. How can it be done?

I tried something like below:

    def build_numb = "ABC/MyABC/XYZ/POC-xyz-api-oci #89"

//    def cleanedString = build_numb.replaceAll(/[^0-9]/, '')
    def BUILD_ID = build_numb.findAll(/\d+/)
    echo "The build id from the string is ${BUILD_ID}"

Any help would be great.

Thanks Pritish

Solution

Using a simple regular expression will find the first number in the string. This code

def build_numb = "ABC/MyABC/XYZ/POC-xyz-api-oci #89"

def matcher = (build_numb =~ /\d+/)
if (matcher) {
    def BUILD_ID = matcher[0]
    print "The build id from the string is ${BUILD_ID}"
}

will print:

The build id from the string is 89
