Everyone keeps saying how simple it is to move a file from point a to point b using fileutils, but I'm having lots of trouble moving a file :(
I have a /temp/ folder in the directory wherever the .jar is located, in this temp folder I have a .txt file I want to move up a directory (so basically next to the .jar file) but I cant seem to do it?
Here's some code, but I know its not even close:
public void replaceFile() {
String absolutePath = getPath();
Path from = Paths.get(absolutePath + "\\temp\\test.txt");
Path to = Paths.get(absolutePath + "\\test.txt");
try {
FileUtils.moveFile(FileUtils.getFile(from.toAbsolutePath().toString()), FileUtils.getFile(to.toAbsolutePath().toString()));
JOptionPane.showMessageDialog(null, "test");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public String getPath() {
File jarDir = new File(ClassLoader.getSystemClassLoader().getResource(".").getPath());
//JOptionPane.showMessageDialog(null, jarDir.getAbsolutePath());
return jarDir.getAbsolutePath();
}
Any help is appreciated :\

Why don't use this Java API for Moving a File or Directory
Files.move(from, to, StandardCopyOption.REPLACE_EXISTING);
UPDATE
Looking at your source code I suggest the following implementation:
Path from = Paths.get(absolutePath, "/temp/test.txt");
Path to = Paths.get(absolutePath, "/test.txt");
try {
Files.move(from, to, StandardCopyOption.REPLACE_EXISTING);
JOptionPane.showMessageDialog(null, "test");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ok i managed to do it, apparently the getPath() method returned some funny path and it failed there, so heres a code that works
public void downloadJar() {
String absolutePath = getPath();
String from = absolutePath + "\\temp\\test.txt";
String to = absolutePath + "\\test.txt";
File fileTo = new File(to);
File fileFrom = new File(from);
try {
FileUtils.moveFile(fileFrom, fileTo);
JOptionPane.showMessageDialog(null, "test");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
JOptionPane.showMessageDialog(null, "io exce");
}
}
public String getPath() {
return System.getProperty("user.dir");
}
thanks everyone
