under picture is jacoco setting in jenkins
under code is jacoco return only 0% coverag.
I think jenkins can not make *.exec file.
So post build result is only 'find 0 exec file'.
What should I do?

I solved this problem by adding under code to catalina.sh in tomcat
code :
JAVA_OPT=" -javaagent: {javaagent.jar location}"
