title: Spring Integration Java DSL Error
body: <p>I have set up a new Spring Boot + Spring Integration + Spring Integration Java DSL project using latest available versions. The project builds okay but, when I run the application, I am getting:</p>
  
  <pre><code>Caused by: java.lang.NoSuchMethodError: org.springframework.integration.dsl.StandardIntegrationFlow.isRegisterComponents()Z

  compile "org.springframework.integration:spring-integration-java-dsl:1.2.3.RELEASE"
  </code></pre>
  
  <p>Could the error be due to wrong combination of jar versions? I am not sure how to debug this error.</p>
