java.io - The system cannot find the file specified

Boas pessoal,

Estou a ter um erro claro que não é encontrado o ficheiro que estou a tentar ler. O meu ficheiro leitura.txt está criado na pasta raiz do projecto "src". E estou a tentar ir ler com o seguinte código:

package ao.co.sistetulene.programa;
import java.io.*;

public class TestaJavaIO {

    public static void main(String[] args) throws IOException {

        //Abrir arquiva para leitura atribuindo a variável do tipo InputStream: "is"
        InputStream  is = new FileInputStream("leitura.txt");

        //Tranformar byte da variável is, em caracter utilizando o encoding padrão do JAVA
        InputStreamReader isr = new InputStreamReader(is);

        //Ler varias linha do texto de uma vez só, utilizando buffer:
        BufferedReader br = new BufferedReader(isr);

    }
}

Ao compilar este código é devolvido a seguinte Exception:

Exception in thread "main" java.io.FileNotFoundException: leitura.txt (The system cannot find the file specified)
    at java.io.FileInputStream.open0(Native Method)
    at java.io.FileInputStream.open(FileInputStream.java:195)
    at java.io.FileInputStream.<init>(FileInputStream.java:138)
    at java.io.FileInputStream.<init>(FileInputStream.java:93)
    at ao.co.sistetulene.programa.TestaJavaIO.main(TestaJavaIO.java:12)

Process finished with exit code 1

Eu estou a utilizar o IntelliJ IDEA 2017.2.3. Em que por cima da Exception tem o seguintes dizer:
