I'm trying to load a jar using

I’m trying to load a jar using jenins but i have error :face_with_spiral_eyes:
java -jar “C:\ProgramData\Jenkins.jenkins\workspace\mavenjob\target\jenkinst-0.0.1-SNAPSHOT.jar”

Error: Could not find or load main class register_User.R_TestBase
Caused by: java.lang.ClassNotFoundException: register_User.R_TestBase

link of class test C:\ProgramData\Jenkins.jenkins\workspace\mavenjob\target\test-classes\register_User

I’m not sure what this has to do with jenkins. Its not our code.
