Application exits with out any error

Question

When I run Spring Boot Application it just shows

objc[2039]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/bin/java (0x108aea4c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x109b544e0). One of the two will be used. Which one is undefined.

Process finished with exit code 1

It was working well I had added unit test related dependencies and removed them after that it has got screwed up.

Here is my POM file
