You generally can't compile a program one file at a time, which is why compiling Evolve.java by itself doesn't work. The different classes in ECJ depend on each other.
The standard way to build ECJ from the command line is to use the Makefile that the zip comes with. Setting up GNU Make on Windows can be tricky, so using Eclipse to build it as as good a route as any.
You need to learn where Eclipse places the files that it compiles. Running ECJ from the command line should be the same as running any other Eclipse project from the command line—so this question is really outside the scope of this list.

Please check this Mr. Siggyi tried in different directories.and also when i compile Evolve.java, i m getting errors. packages are not imported as expected. do you have any idea about this?On Mon, Feb 1, 2016 at 12:36 AM, Eric 'Siggy' Scott <[log in to unmask]> wrote:Vimaladevi,To run a Java class from the command line, you need to either be in the directory containing the compiled .class files,or have those files in your classpath.I'm not an Eclipse user, so I don't know where Eclipse places the .class files. But if I were to take a guess—you might tryrunning the command from inside the 'test' directory instead of the 'test/ec' directory?SiggyOn Sun, Jan 31, 2016 at 1:22 PM, Vimaladevi M <[log in to unmask]> wrote:Hi Mr. SiggyThanks for your reply.i imported ecj\ec files into a new project in eclipse.when i tried to run it, i got the below error in eclipse console and command prompt too."Error: Could not find or load main class ec.Evolve"but i was able to clear this error now. for this what i did was deleted ".metadata" folder and created a new project again and imported the ecj\ec classes. i m able to run the tutorial1 using eclipse. but the problem still persists if i run through command prompt. please see the below screenshot.On Sun, Jan 31, 2016 at 8:52 PM, Eric 'Siggy' Scott <[log in to unmask]> wrote:Vimaladevi,Can you give us some more information?
