For example, suppose the JUnit tests are located in a file named Tester.java. Replace ClassName with the name of the class with the JUnit tests. To run your tests, you can use the following command: You need to make sure your classpath is setup (see above) first. You can run JUnit tests via the command-line on the lab computers. For this to work, your *.jar file must contain ALL of the necessary classes for your program to run. Replace filename.jar with the name of your jar file (assuming it is in the current directory). Java -cp filename.jar ClassName arguments To execute your code, run the following command:

If you have already packaged your *.class files in a *.jar file, you can skip compiling your code with javac. If you must specify a file name with a space inside it, use quotes around the filename: To execute your code with the argument, run the following command:
JAVA JAR FILE NOT FOUND DRIVER
For example, suppose the class Driver takes a filename as an argument. with your command-line arguments (separated by spaces). If you want to provide command-line arguments to your program, just include those arguments after the class name: Double-check that your classpath is setup correctly and that your code is properly compiled. In this case, javac cannot figure out where the class files are located. If you have not setup your classpath yet, you need to also provide a -cp "." parameter to tell the java tool to look for your *.class files in the current directory.Ī common error if you do not have your classpath setup properly will be similar to:Įxception in thread "main" : Replace ClassName with the classname (no file extension) that contains your main() method. To run your code, you need to know which class has the main() method. Double-check that your classpath is setup correctly. In this case, javac cannot figure out where the third-party libraries like junit are located. Those are the files necessary to execute your Java code.Ī common error if you do not have your classpath setup properly will be similar to: error: package org.junit does not exist Now, when you ls your directory, you should notice you also have *.class files. You first need to compile these files using Java. Remember, Java source code is always stored a *.java file.
Make sure you are currently in the directory with your source code files. (It is okay if there are extra directories in the output.) Compile You should see all of the directories you specified in your $CLASSPATH variable above. If it is setup correctly, you will see something similar to the following: If that looks correct, run the following command as well: You should see somewhere in the output the following lines (there may be other lines as well): To test that everything is setup, try the following command: You can also add that directory (or any other) to your $CLASSPATH variable by adding the additional line:Įxport CLASSPATH="$CLASSPATH:/home/public/cs212/libraries/*" For example, the CS 212 course places third-party libraries at /home/public/cs212/libraries/ on the lab computers. Some classes also provide some third-party libraries for you on the lab computers. If it does not exist yet, go ahead and create it. See the Using Linux via Command Line guide if you are unfamiliar using a text editor via the command line prior to completing this guide.Ĭhange to your home directory (run cd ~ at the prompt) and open the. To do this, you will need to edit a configuration file in your home account. This becomes especially important when you start using third-party libraries and must include multiple jar files. jar file will start running smoothly.You need to set your $CLASSPATH variable on the lab computers, or you will be stuck specifying long classpath parameters every time you run java.
