I am using maven and I am creating an application that needs to get files from src/main/resources upon running an exe.

I used this to generate an exe upon build > http://www.hascode.com/2012/08/creating-a-windows-executable-from-a-jar-using-maven/

I am getting an error that it cannot access the files inside src/main/resources when running the exe file.

I use this to get the files from src/main/resources

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
File[] files = new File(classLoader.getResource("files").getFile()).listFiles();

When I run it in eclipse, it runs but when I run it using exe,

using eclipse: No error

DEBUG file:/C:/Development/Java/eclipse/workspace/app_sample/target/classes/files
DEBUG /C:/Development/Java/eclipse/workspace/app_sample/target/classes/files

using exe:

DEBUG file:/C:/Users/User.Name/Desktop/just%20some%20directory/App.exe!/files
ERROR java.lang.NullPointerException

Guessing: The compiled program is looking for `src/main/resources/` in the working directory, i.e. where it is being executed. Please post your code where you are trying to access this directory. – Thomas Timbul Apr 11 '18 at 10:30
can you post how do you get files from src/main/resources ? – Elarbi Mohamed Aymen Apr 11 '18 at 10:33

ClassLoader classLoader = getClass().getClassLoader(); File file = new File(classLoader.getResource(fileName).getFile()); – DarthDeveloper Apr 11 '18 at 10:48
