Spring Boot: hot swapping does not work
<p>I'm using Spring Boot 1.3.2 with gradle plugin. In my multipart project hot swapping/reload for HTML/JS/CSS files does not work.</p>

<pre><code>/resources
  |-wro.groovy
  |-application.yml
  |-/templates/(all *.html files and index.html)
  |-/static/
      |-/js/
      |-/css/
</code></pre>

<p><strong>application.yml</strong></p>

<pre><code>server:
 port: 8080

spring:
  thymeleaf:
    cache: false
    prefix: classpath:/templates/
    suffix: .html
    enabled: true
    encoding: UTF-8
    mode: HTML5
</code></pre>

<p>In te projet also used: wro4j, thymeleaf, AngularJS</p>

<p>Part of <strong>gradle.build</strong></p>

<pre><code>buildscript {
    ext { springBootVersion = '1.3.2.RELEASE' }
    repositories {
        maven {
            url "https://ourartifactoryUrl/plugins-release"
            credentials {
                // artifactory log and pass
            }
        }
    }
    dependencies {
        classpath group: 'org.springframework.boot', name: 'spring-boot-gradle-plugin', version: springBootVersion
        classpath group: 'io.spring.gradle', name: 'dependency-management-plugin', version: '0.5.2.RELEASE'

   compile("org.springframework.boot:spring-boot-devtools")
}
</code></pre>

<p>Project executed with: <code>gradle :web-admin:bootRun</code></p>

<p><strong>Update/Answer:</strong> </p>

<p>After some surfing in internet and reading spring-boot docs I found one trick. 
Problem in using <a href="https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-gradle-plugin.html#build-tool-plugins-gradle-running-applications" rel="nofollow"><code>devtools</code> together with <code>spring-boot-gradle-plugin</code></a> as a result I simply need to add to my <strong>gradle.build</strong> file few lines: </p>

<pre><code>    // Used by 'Spring Boot Gradle Plugin' in combination with 'Devtools' makes HTML/JS/CSS reloadable.
    bootRun {
        addResources = true
    }
</code></pre>
