Issue while executing scala spark code

Hello team,

I am a new to spark and done some trainings recently along with my colleagues. There are set of precompiled codes which are executing for others however i am getting below error message:
actions taken: deleted repository folder under .m2 folder. and restarted eclipse. all errors resolved after build path is finished.

however while running any code i am getting almost similar error.

ERROR MESSAGE:
