Additional jar files for java.exe -jar

Question

I run the following command:

C:\\Projects\\java -cp ./dependency.jar -jar ./dist/main.jar
Exception in thread \"main\" java.lang.NoClassDefFoundError: MyExceptio         


        

Answer 1

The -cp options is ignored if you use -jar. If you need extra jar-files on the class-path, you should specify this in the Manifest of main.jar like this:

Class-Path: dependency.jar

(Then you can run your program using java -jar main.jar.)

Answer 2

Have you tried specifying the class path in the windows environment variable CLASSPATH ?

specify your environment variable CLASSPATH and put the value of your JAVA_HOME\lib and (path to all your classes) and also include current directory by including (dot or period sign).
