How to include Java classes when compiling from Command Line?

Question

I've usually used an IDE for my Java programs but I've recently switched to the Command Line.

I created several classes that are in the same directory as my "main" program that I wish to compile. However, the command 'javac -cp test.jar ColorTester.java' yields:

ColorTester.java:24: cannot find symbol
symbol  : class IntToColor
location: class ColorTester
      IntToColor colorFunc = new ModThreeToColor(testColor,
      ^

My classes IntToColor and ModThreeToColor have both been compiled into class files, but it's still not making a difference.

The IDE had always taken care of this for me, so as you can imagine I'm quite confused.

Thank you.

Answer 1

Like this:

java -classpath <here> Program

Replacing <here> with the list of classes and/or jars and/or packages that make up your classpath, separated by the : character on Unix (or the ; character in Windows). There's plenty of documentation online, for example read this link .

Answer 2

在命令行类路径中包括当前目录。

javac -cp test.jar:. ColorTester.java
