You can encounter the following error:

Caused by: java.lang.NoSuchMethodError: org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry.hasMappingForPattern(Ljava/lang/String;)Z
at org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter.addResourceHandlers(WebMvcAutoConfiguration.java:256)
at org.springframework.web.servlet.config.annotation.WebMvcConfigurerComposite.addResourceHandlers(WebMvcConfigurerComposite.java:102)

Using `gradle dependencies` didn't help me much.

It showed the right dependency I expected:

org.springframework:spring-webmvc:4.1.6.RELEASE

It's one of Gradle sub-projects.

It is caused by another sub-project which it depends on.

The sub-project has a dependency having the following transitive dependency:

org.springframework.mobile:spring-mobile-device:1.1.3.RELEASE

And it has the following transitive dependency:

org.springframework:spring-webmvc:3.2.11.RELEASE

So the conflict occurred.

I solved it as follows:

    compile("xxx:xxx:1.0.0") {
        exclude module: 'spring-mobile-device'
    }

But I can't understand why the latest dependency doesn't win.
