"Robot Code" won't turn green, but no errors are displayed

I had the same issue during the San Diego Competition.
Make sure all sensors that you are calling actually exist, it took me a while but I found that I was calling for a Sonic Sensor on Analog port 1 when it was on port 0.

I would just make a very simple program and seeing if that uploads

package org.usfirst.frc.team3647.robot;

import edu.wpi.first.wpilibj.BuiltInAccelerometer;

/**
 * The VM is configured to automatically run this class, and to call the
 * functions corresponding to each mode, as described in the IterativeRobot
 * documentation. If you change the name of this class or the package after
 * creating this project, you must also update the manifest file in the resource
 * directory.
 */

public class Robot extends IterativeRobot {

	private BuiltInAccelerometer accel = new BuiltInAccelerometer();
	
	public void robotInit() {
	
	}

	/**
	 * This function is called periodically during autonomous
	 */
	 public void autonomousInit(){
	    	
	    }
	
	public void autonomousPeriodic() {

	}

	/**
	 * This function is called periodically during operator control
	 */
	public void teleopPeriodic() {
		SmartDashboard.putData("Test", accel);
	}

	/**
	 * This function is called periodically during test mode
	 */
	public void testPeriodic() {

	}
}
