How read all files in the folder and replace the pattern in file using Groovy - groovy

Question

import groovy.io.FileType
import java.io.File;
def list = []
def dir = new File("C:\\Users\\Desktop\\CodeTest")
dir.eachFileRecurse (FileType.FILES)
{
file ->list << file
}
list.each
{
println it.path
}
//Replace the pattern in file and write to file sequentially.
def replacePatternInFile(file, Closure replaceText)
{
file.write(replaceText(file.text))
}
def file = new File(file)
def patternToFind1 = ~/</
def patternToFind2 = ~/>/
def patternToReplace1 = '&lt'
def patternToReplace2 = '&gt'
//Call the method
replacePatternInFile(file){
it.replaceAll(patternToFind1,patternToReplace1)
}
replacePatternInFile(file){
it.replaceAll(patternToFind2,patternToReplace2)
}
println file.getText()
I am able to change the pattern for one file but I want to read all the files in the folder and replace the pattern in each file one by one
while executing it:
ERROR:An error occurred [Could not find matching constructor for: java.io.File(java.util.ArrayList)], see error log for details

Answer 1

You have many problems with your code...
1) You don't need to import:
import java.io.File;
2) When you call:
def file = new File(file)
There is no variable called file in new File(file) (did you mean files?)
3) If you did mean new File(files) then that is where your error is... You can't make a new file from a list of Strings
4) The entity for > is > NOT &gt... The same for < (it needs a semicolon at the end)
You will need to iterate your list of Strings (files.each { path -> ?) and then work on each one in turn.
Though 2) and 3) make me suspect that the above code isn't your real code, but a pretend copy from memory (or a badly redacted copy), as the above code will not give you the error you say you're getting
