File IO not working

I am facing some issue while ruing a maven project job on Jenkins. According to code, it should create a new File on the location passed. Using below code for the same.

String fileName = "C://DevTools/abc.txt"
File file = new File(fileName);
file.createNewFile();      //returning false

When I surrounded the above code in try-catch block, it threw Exception 'Caot find the file path on system'. I checked the path in System manually, it was correct.But when I tried creating a new file using FileUtils (Apache common IO), it created the file successfully. Is there any reason behind this?
