Gradle中如何声明一个Java中可使用的变量呢?

Gradle声明java变量的实现思路:
      debug {
	     buildConfigField "类型" "名字" "变量值"
	  }

android {
    buildTypes {
        debug {
            buildConfigField "int", "Test", "898"
            buildConfigField "String", "Test_STRING", "\"java265\""
            buildConfigField "boolean", "LOG", "true"
        }

        release {
            buildConfigField "int", "Test", "898"
            buildConfigField "String", "Test_STRING", "\"java265\""
            buildConfigField "boolean", "LOG", "false"
        }
    }
}
