gradle - 为什么gradle不打印属性文件？

Question

我试图从gradle / groovy中执行简单的打印语句，但出现错误

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

ext.appVersion=extProgram['version']

println ext.appVersion

这是我得到的错误

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: "{}".

这是因为extProgram被假定为项目的属性。
尝试以下方法:

def extProgram = new Properties()
...

这将extProgram定义为局部变量。
