爲什麼gradle不打印屬性文件？

Question

我試圖從gradle產出/ Groovy中執行簡單的print語句，但我得到的錯誤

extProgram = new Properties() 
extProgram.load(new FileInputStream("src/main/resources/version.txt")) 

ext.appVersion=extProgram['version'] 

println ext.appVersion 

這是錯誤我得到

Creating properties on demand (a.k.a. dynamic properties) has been deprecated and is scheduled to be removed in Gradle 2.0. Please read http://gradle.org/docs/current/dsl/org.gradle.api.plugins.ExtraPropertiesExtension.html for information on the replacement for dynamic properties. 
Deprecated dynamic property: "extProgram" on "root project 'appController'", value: "{}".

這是因爲extProgram被假定爲一個屬性該項目。 試試這個：

def extProgram = new Properties() 
... 

這extProgram定義爲一個局部變量。
