Okta Spring Boot Starter doesn't work with spring-cloud-starter-gateway

[mraible]

The Okta Spring Boot Starter (v0.1.0) works when adding to a Spring Boot Eureka server. However, when I try to use it with spring-cloud-starter-gateway, it fails. Once I include the dependency, the following message is printed on startup.

2017-11-04 10:43:57.196  WARN 73027 --- [           main] 
GatewayClassPathWarningAutoConfiguration : 

**********************************************************

Spring MVC found on classpath, which is incompatible with Spring Cloud 
Gateway at this time. Please remove spring-boot-starter-web dependency.

**********************************************************

If I exclude spring-boot-starter-web, stuff blows up because there's no javax/servlet/Filter in the classpath.

Caused by: java.lang.NoClassDefFoundError: javax/servlet/Filter

If I add javax.servlet-api as a dependency:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
</dependency>

It blows up with the following exception:

@mraible, i'm not seeing spring-cloud-starter-gateway in Maven Central, do you still have that pom you used when opening this issue? I think the fix should be just adding a conditional, I wanted to test it out before the next release.

If you use start.spring.io and select 2.0.0 M7, then select "gateway", you'll see its coordinates in the pom:

This should already be in v0.3.0, it was an ordering problem with cloud-conf IIRC.
