I have a Maven project and within that I have a Main.java
class that contains the main()
method that I would like to execute from Windows command prompt. I am using the following command to execute it but it fails with an error message (show below). This program works fine from IDE.
Similar question at stackoverflow Why am I getting a NoClassDefFoundError in Java? has been listed but does not provide a solution. It only explain the problem in a detailed manner.
Please guide.
Command to execute main class:
java -classpath targetjobchain-dataloader.jar com.ebayenterprise.ecp.jobs.Main
Error Log:
C:office-datav11-Projectsjobchain-dataloader>java -classpath targetjobchain-dataloader.jar com.ebayenterprise.ecp.jobs.Main
Error: A JNI error has occurred, please check your installation and try again
