When developing a springboot project,i had encountered the above error.What's weird is that the project runs well in IDEA and report exception running as a jar.And more weird thing is that my colleagues can package a non-exception jar! So I think it is something wrong with my own computer environment.
here is the versions of tools of my computer： Maven 3.6.2 Java version: 1.8.0_181
here is the pom file:
