this happening because packaging spring-boot-starter-tomcat (embedded tomcat) dependency war.
basically need in order package deployable war apply war plugin, , set dependency scope providedruntime.
apply plugin: 'war' ... dependencies { compile("org.springframework.boot:spring-boot-starter-web") providedruntime("org.springframework.boot:spring-boot-starter-tomcat") ... } for more, see spring boot gradle plugin,
especially section 59.4 packaging executable jar , war files
this link: create deployable war file, maybe useful.
