How to copy files in Groovy

Question

I need to copy a file in Groovy and saw some ways to achieve it on the web:

1

new AntBuilder().copy( file:\"$sourceFile.canonicalPath\", 
                  


        

Answer 1

I prefer this way:

def file = new File("old.file")
def newFile = new File("new.file")
Files.copy(file.toPath(), newFile.toPath())

Answer 2

To append to existing file :

def src = new File('src.txt')
def dest = new File('dest.txt')
dest << src.text

To overwrite if file exists :

def src = new File('src.txt')
def dest = new File('dest.txt')
dest.write(src.text)
