Question

here is the structure of my project.

proj
  ---src
    ----main
        ----java
            ----Main.java
        ----resources
             ----res.txt

I am using m2eclipse plugin with Eclipse.
In Main.java, I have

File f = new File("res.txt");  System.out.println(f.getAbsolutePath());

When I run mvn exec:java, the path got printed out is “…\proj\res.txt”. How can I make it look for the resource file in “…\proj\target\classes” directory?

EDIT:

Thanks for the answers to my original question. I have a follow-up questions:

So basically what I want to do is to have the Main class read the “res.txt” and then generate a new “newres.txt” to the resources directory so that I can package this new “newres.txt” to the jar file in the package phase later. Currently I mounted this exec:java to the prepare-package phase. How should I create this “newres.txt” in the resources directory without a hard-coded absolute path or depending on the directory structure of Maven?

Answer 1

I guess I will answer my own question, Thread.currentThread().getContextClassLoader().getResourceAsStream()
works the best for me, especially when the project produces a jar dependency for another web project.
