Question

Method to copy entire directory contents to another directory in java or groovy?

Answer 1

FileUtils.copyDirectory()

Copies a whole directory
to a new location preserving the file
dates. This method copies the
specified directory and all its child
directories and files to the specified
destination. The destination is the
new location and name of the
directory.

The destination directory is created
if it does not exist. If the
destination directory did exist, then
this method merges the source with the
destination, with the source taking
precedence.

To do so, here’s the example code

String source = "C:/your/source";
File srcDir = new File(source);

String destination = "C:/your/destination";
File destDir = new File(destination);

try {
    FileUtils.copyDirectory(srcDir, destDir);
} catch (IOException e) {
    e.printStackTrace();
}
