Error: while building appsensor ui

[Shamsi12]

I am facing error while running 7 step.

Start AppSensorUI

go to this directory: https://github.com/jtmelton/appsensor/tree/master/appsensor-ui
run this command:
mvn spring-boot:run -DAPPSENSOR_REST_REPORTING_ENGINE_URL=http://localhost:8085 -DAPPSENSOR_CLIENT_APPLICATION_ID_HEADER_NAME=X-Appsensor-Client-Application-Name2 -DAPPSENSOR_CLIENT_APPLICATION_ID_HEADER_VALUE=myclientapp -DAPPSENSOR_WEB_SOCKET_HOST_URL=ws://localhost:8085/dashboard -Dspring.datasource.url=jdbc:mysql://localhost/appsensor -Dspring.datasource.username=appsensor_user -Dspring.datasource.password=appsensor_pass i.

I don't familiar with the error it might be some sort of exception being generated when i run this command.I have followed all step clearly and completely. Kindly, give solution, i am setting the screenshot of the error below.
