Why doesn't Tomcat start?

Question

Java

Ruled some trifle that does not affect the work.
Suddenly, for no apparent reason, the tomcat refuses to launch it.
other applications that are 100500% working and were in the working folder - now fall with the same error.

how to treat:
deleted .m2 folder
reinstalled JDK, Eclipse, Tomkat (3 different versions)
deleted the project and its .settings .classpass folders and exported it again.
maven clean
doesn't help

Answer 1

I found the reason. the library was missing.
then another one ... then another ... And this despite the fact that before that everything worked and so!
In short, after the fifth library added to the pom, it turned out that initially, in the process of replacing everything, I installed 14 instead of the 8th JDK. I
took everything to hell. I installed 8jdk 8 jre and everything worked like clockwork and 2 times faster.
Amen!
