  • Is `jetty-server` added as dependency? – Smile Aug 13 '20 at 11:42
  • yes. I tried to add the dependency for jetty-server. The error is not shown. After creating pom from Spring Initializr, it was running good. I added some dependencies manually such as Jsoup, javax.enterprise, com.google.elemental2, then exception is thrown. – Thangaraj Aug 13 '20 at 11:52
  • So, it works after adding jetty-server dependency? – Smile Aug 13 '20 at 11:55
  • I dont want to run Jetty server, I am trying to run tomcat server in spring boot. The problem is GWT. The gwt eclipse plugin is running the Jetty server while i run java application spring boot. – Thangaraj Aug 13 '20 at 23:18

for me i only use Tomcat but after i migrated springboot 1.x -> 2.x and added springfox on dependencies I started to have the same error.
it was only ok on IDEA but not on external tomcat.

following up the code on EmbeddedWebServerFactoryCustomizerAutoConfiguration.java it was trying to auto configure with JettyWebServerFactoryCustomizer then as JettyWebServerFactoryCustomizer class depend on a lot of jetty package classes it threw the error.

the solution is. i just excluded EmbeddedWebServerFactoryCustomizerAutoConfiguration from bean list and it worked perfectly. tomcat is now default embedded server and it doesn't try to configure with any others.

try this annotation on your Spring Boot Application.

@SpringBootApplication(exclude = org.springframework.boot.autoconfigure.web.embedded.EmbeddedWebServerFactoryCustomizerAutoConfiguration.class)
