Question about NoSuchMethodError

[Shinigami345]

http://pastebin.com/index/JQqpB82F When I run the specchecker I get this weird error
PROBLEM:
java.lang.NoSuchMethodError: org.junit.Assert.assertEquals(Ljava/lang/String;JJ)V like 40 times.

I mean real it's taking off like 90% of my points on the homework. I need to turn this in in about 2-3 hours the pastebin includes the spec for the code that i'm supposed to write a link to the spec checker and my source code. I'm pretty sure my if statements are weird and I know my code is uglay but I'm lazy and it's just checked by a computer so I don't have to write pretty code.

The missing assertion method seems to be a problem of the specchecker. Maybe the JUnit library is missing.

Edit: I ran it and it says

java -jar speccheck_pre1.jar
1. RUNNING TESTS
Did you add JUnit to your project?

So did you add it to your project?

I have a tab or whatever for JUnit 4. Under that it has another one for Referenced Libraries and the specchecker is in that. I thought I sat it up how they told me to.

If it is not the library that is missing, it is the code of the specchecker. Talk to your instructor.
