title: Parse yaml return empty object
body: <p>I have the following yaml which I need to parse to struct.
  In the builds property I got empty value while debug, what am I missing here? </p>
  
  <p>I use "gopkg.in/yaml.v2"</p>
  
  <pre><code>- name: srv
      type: java
      path: srv
      builds:
       - name: db
          properties:
             JBR_CONFIG_RESOURCE_CONFIG: '[META-INF/context.xml:
                {"service_name" : "~{h-container}"}]'
             TEST2: aaaa
  </code></pre>
  
  <p>The struct is </p>
  
  <pre><code>type Runs struct {
      Name       string
      Type       string
      Path       string     `yaml:"path,omitempty"`
      Builds   []Builds `yaml:”builds,omitempty"`
  }
  
  type Builds struct {
      Name       string     `yaml:"name,omitempty"`
      Properties Properties `yaml:"properties,omitempty"`
  }
  
  type Properties map[string]string
  </code></pre>
