title: excludeDevtools seems to have no effect under Spring Boot 1.5.1.RELEASE (but OK in 1.4.4.RELEASE)
body: <p>I've created a fresh new Spring Boot 1.5.1.RELEASE project with a devtools dependency:</p>
  
  <pre><code>dependencies {
      compile('org.springframework.boot:spring-boot-starter-thymeleaf')
      compile('org.springframework.boot:spring-boot-starter-web')
      compile('org.springframework.boot:spring-boot-devtools')
      testCompile('org.springframework.boot:spring-boot-starter-test')
  }
  </code></pre>
  
  <p>When running from inside Idea this works no problem.  However, after performing a bootRepackage, the resulting fat jar has no devtools jar in its lib folder.  I have the following entry in build.gradle:</p>
  
  <pre><code>bootRepackage {     
      mainClass = 'com.example.HotreloadApplication'
      excludeDevtools = false 
  }
  </code></pre>
  
  <p>And upon a ./gradlew bootRepackage and a java -jar build/libs/hotreload-0.0.1-SNAPSHOT.jar, I can see that it fires up without devtools still.  Upon opening the jar, I can also see that it is not included.</p>
  
  <p>When moving springBootVersion back to '1.4.4.RELEASE' howeverm everything works absolutely as expected.</p>
  
  <p>Any help would be greatly appreciated!  I've included the entirety of my build.gradle following this message.</p>
  
  <p>Many thanks,
  Duncan</p>
