Top Most How to fix java.io.FileNotFoundException: (Access is denied)

Earlier my impression was that java.io.FileNotFoundException: (Access is denied) comes when you try to read a text or binary file for which you don't have permission from Java program but this can also come while you are using jar command. jar command internally use java.util.zip.ZipFile class to open any jar or war file which can throw java.io.FileNotFoundException: (Access is denied). I was trying to see contents of war file which was created using recent build when I stumble upon this error, see the exact command below:

test@dev454:war-store/target jar -tvf maven-eclipse-web-demo
java.io.FileNotFoundException: maven-eclipse-web-demo (Access is denied)
