I have a problem trying to understand why I am not getting a main class 
in this situation that I inherited from another developer.

We have this file stack

gradle build config is:

[ruben@localhost assn2]$ cat build.gradle 
apply plugin: 'java'

sourceSets {
    main {
        java {
            srcDir 'src'
        }
    }
    test {
        java {
            srcDir 'src'
        }
    }
}

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'junit', name: 'junit', version: '4.+'
    compile group: 'com.google.guava', name: 'guava', version: '19.+'
}

TWO classes have main
[ruben@localhost assn2]$ cd ./src/pico/
[ruben@localhost pico]$ ls
Lexer.java  LexError.java  LexerTest.java  Token.java
[ruben@localhost pico]$ grep main ./*
grep: ./.gradle: Is a directory
./Lexer.java:    public static void main(String[] args) {
Binary file ./.Lexer.java.swp matches
./Token.java:    public static void main(String[] args) {
