JUnit error: Could not find or load main class (RemoteTestRunner)

Question

I've downloaded Junit version 4.10 and loaded the jar via the build path but I seem to get this error message when running a Junit test in Eclipse:

Error: Could not find or load main class org.eclipse.jdt.internal.junit.runner.RemoteTestRunner

My Test class is the following:

import org.junit.*;
import static org.junit.Assert.assertEquals;



public class InternetConnectTest {

@Test
public void testConnectMethod(){

    InternetConnect net = new InternetConnect("www.google.com");
    assertEquals("Result", "www.google.com", net.url);


}

}

If anyone else stumbles across this - if you're running Eclipse on Windows try using "Run as administrator..." when you open Eclipse. Seemed to do the trick for me with the same problem. — Tim Ackroyd, Sep 02 '13 at 08:55

I came across this after I updated java versions: "junit: could not load main class 1.1". Go into the eclipse external tools configurations, open the entry for the ant file you are running, then go to the JRE tab, and select "Separate JRE", also making sure your new jre is correctly listed in the Installed JREs...for me, this took care of it.

This is an Eclipse error message. It seems your installation is corrupted. Try using a fresh installation of Eclipse.

Thanks, this did the trick. I've been having to re-install quite a lot recently - Is Eclipse usually this unstable ? – MeMory LEAk99 May 02 '12 at 15:30
As noted by @David, try simply restarting Eclipse before doing anything drastic like reinstalling, worked for me! – Mike Ounsworth Jun 10 '15 at 19:25

I just had the same problem. I relaunch Eclipse with the "-clean" option, and it did the trick too.

Edit: How to run eclipse in clean mode? and what happens if we do so?
