声明中gradle.properties文件阵列/ HashMap的 [英] Declare array/hashmap in gradle.properties file

问题描述

我试图来定义gradle.properties文件的数组。当，比如我做下一些脚本的gradle：

I'm trying to define an array in the gradle.properties file. When, for example, I do the next in some gradle script:

project.ext.mygroup = [
  myelement1: "myvalue1",
  myelement2: "myvalue2"
]
project.mygroup.put("myelement3", "myvalue3"); // As internally it works like a hashmap

然后我列出的属性，我得到：

and then I list the properties, I get:

mygroup: {myelement1=myvalue1, myelement2=myvalue2, myelement3=myvalue3}

所以，如果我尝试设置一个属性与在gradle.properties文件相同的形式：

So, if I try setting a property with the same form in the gradle.properties file:

mytestgroup={myelement1=myvalue1, myelement2=myvalue2}

然后在剧本的gradle我尝试访问该属性：

And then in the gradle script I try to access this property:

project.mytestgroup.put("myelement3", "myvalue3");

我得到下一个错误：

I get the next error:

No signature of method: java.lang.String.put() is applicable for argument types: (java.lang.String, java.lang.String) values: [myelement3, myvalue3]

这是因为在属性mytestgroup是被当作字符串而不是阵列。

This is because the property "mytestgroup" is being taken as a string instead of an array.

是否有任何人知道什么是正确的语法来声明在gradle.properties一个数组文件？

Does any one know what is the correct syntax to declare an array in the gradle.properties file?

在此先感谢

推荐答案

记号 {myelement1 = myvalue1，myelement2 = myvalue2，myelement3 = myvalue3} 是一个简单的字符串重该对象调用 Map.toString的结果presentation（）。这是不正确的语法Groovy的。

The notation {myelement1=myvalue1, myelement2=myvalue2, myelement3=myvalue3} is simply a string representation of the object as the result of calling Map.toString(). It is not syntactically correct Groovy.

您第一个例子是确定正确的方式地图。

Your first example is the correct way to define a Map.

def myMap = [ key : 'value' ]

定义的数组是相似的。

Defining an array is similar.

def myArray = [ 'val1', 'val2', 'val3' ]
