In Groovy how to replace a string in a file?

Question

I'm following the answer given in Replace the string in file using groovy, but am getting an error. I just want to replace, for example

From
version=1.1.0

To
version=1.1.1

in some file. I do

String sv1 = '1.1.0'
String sv2 = '1.1.1'
def file = new File(`/some_path/someFile')
def fileText = file.replaceAll("version=$sv1", "version=$sv2")
file.write(fileText)

I get

Caught: groovy.lang.MissingMethodException: No signature of method: java.io.File.replaceAll() is applicable for argument types: (org.codehaus.groovy.runtime.GStringImpl, org.codehaus.groovy.runtime.GStringImpl) values: [version=1.1.0, version=1.1.1]

    at pre-push.run(pre-push:219)

Are the dots (.) in the string messing it up? What's the proper syntax if so? Thanks.

You need to call replaceAll() on the file's contents, not on the File instance itself.

def fileText = file.text.replaceAll("version=$sv1", "version=$sv2")

The answer in the link I referred to is wrong then. This is the correct way to do it. – Chris F Dec 03 '19 at 00:54

This will do your entire task in one line

new File(`/some_path/someFile').text=new File(`/some_path/someFile').getText().replaceAll("version=1.1.0", "version=1.1.1")
