Trying to Replacing a string in a file using groovy DSL

Question

I want to replace VERSION placeholders in a file to a variable version value, but I'm running into the below error:

def versions = ["8.8.0", "9.9.0"]
versions.each { version ->
    def file = new File("$Path/test.url")
        def fileText = file.replaceAll("VERSION", "${version}")
            file.write(fileText);

Error:

groovy.lang.MissingMethodException: No signature of method: java.io.File.replaceAll() is applicable for argument types: (java.lang.String, org.codehaus.groovy.runtime.GStringImpl) values: [VERSION, 8.8.0]

I'm a newbie to groovy dsl, not sure what I'm missing, any suggestions, appreciated !

Answer 1

Another way is to use the groovy file .text property:

def f = new File('sample-file.txt')
f.text = f.text.replaceAll('VERSION', '8.8.0')

and like @cfrick mentioned, there is not much point in performing the replace operation on multiple versions as only the first one will actually find the VERSION string.

Running the above on a sample file:

─➤ groovy solution.groovy
─➤ 

will result in the string being replaced:

─➤ diff sample-file.txt_original sample-file.txt
1c1
< Dolore magna aliqua. VERSION Ut enim ad minim veniam.
---
> Dolore magna aliqua. 8.8.0 Ut enim ad minim veniam.

where diff is a linux tool for comparing two files.
