JUnit - java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing - junit

Question

I am using Win 7 and downloaded Junit 4.13 and hamcrest 2.1 from
https://github.com/junit-team/junit4/wiki/Download-and-Install
and put them in a folder named JUnit under C.
I have added the variable: JUNIT_HOME with value C:\JUnit.
I have also added the following to my classpath:
%classpath%;.;C:\Program Files\Java\jre1.8.0_171\bin;%CLASSPATH%;
%JUNIT_HOME%\junit-4.13-beta-1;.; %JUNIT_HOME%\hamcrest-core-2.1.jar;
Following https://github.com/junit-team/junit4/wiki/Getting-started,
I added the java files Calculator.java and CalculatorTest.java to my practice folder.
The command
javac -cp .;junit-4.13-beta-1.jar;hamcrest-core-2.1.jar CalculatorTest.java
is executed successfully. However, the command
java -cp .;junit-4.13-beta-1.jar;hamcrest-core-2.1.jar org.junit.runner.JUnitCore CalculatorTest
Fails, giving an error message like
Exception in thread "main" java.lang.NoClassDefFoundError:

The correct hamcrest jar is hamcrest-2.1.jar, not hamcrest-core-2.1.jar. You can download it from here.
According to mentioned guide it is assumed you have downloaded jars in the same package as your project:
Create a new folder junit-example and download the current
junit-4.XX.jar from JUnit's release page and Hamcrest to this folder.
If you decided to put jars separately probably you need to correct the command line correspondingly to take these jars files from %JUNIT_HOME%:
java -cp .;%JUNIT_HOME%\junit-4.13-beta-1.jar;%JUNIT_HOME%\hamcrest-core-2.1.jar org.junit.runner.JUnitCore CalculatorTest
