how to fix groovy.lang.MissingMethodException: No signature of method:

Because you are passing three arguments to a four arguments method. Also, you are not using the passed closure.

If you want to specify the operations to be made on top of the source contents, then use a closure. It would be something like this:

def copyAndReplaceText(source, dest, closure){
    dest.write(closure( source.text ))
}

// And you can keep your usage as:
copyAndReplaceText(source, dest){
    it.replaceAll('Visa', 'Passport!!!!')
}

If you will always swap strings, pass both, as your method signature already states:

def copyAndReplaceText(source, dest, targetText, replaceText){
    dest.write(source.text.replaceAll(targetText, replaceText))
}

copyAndReplaceText(source, dest, 'Visa', 'Passport!!!!')

You can also get this error if the objects you're passing to the method are out of order. In other words say your method takes, in order, a string, an integer, and a date. If you pass a date, then a string, then an integer you will get the same error message.

To help other bug-hunters. I had this error because the function didn't exist.

I had a spelling error.

In my case it was simply that I had a variable named the same as a function.

Example:

def cleanCache = functionReturningABoolean()

if( cleanCache ){
    echo "Clean cache option is true, do not uninstall previous features / urls"
    uninstallCmd = ""
    
    // and we call the cleanCache method
    cleanCache(userId, serverName)
}
...

and later in my code I have the function:

def cleanCache(user, server){

 //some operations to the server

}

Apparently the Groovy language does not support this (but other languages like Java does). I just renamed my function to executeCleanCache and it works perfectly (or you can also rename your variable whatever option you prefer).
