gradle - Groovy:多次声明字段属性

Question

我想从gradle.properties获取自定义插件类中变量的值。但是我想在apply方法之外编写和使用它。所以，我这样写:

class VCPlugin implements Plugin<Project> {

   private Project project

   private Properties properties
   properties = new Properties()
   properties.load(project.rootProject.file('gradle.properties').newDataInputStream())
   def componentClass = properties.getProperty('componentClass')

   @Override
   void apply(Project project) {
      //applying distribution plugin
      this.project = project .....
   }
}

但这会产生编译错误:

Groovy:The field properties is declared multiple times

现在，如果我在apply方法中编写它，那么它可以工作，但是我需要在apply方法之外使用 componentClass变量，因此我需要在外部编写它。任何帮助将不胜感激。

下面的代码可以完成这项工作:

 class VCPlugin implements Plugin<Project> {

  private Project project
  private Properties properties
  private String componentClass 

  @Override
  void apply(Project project) {
    this.project = project
    this.properties = new Properties()
    properties.load (project.rootProject.file('gradle.properties').newDataInputStream())
    this.componentClass = this.properties.getProperty('componentClass')
  }
}
