为什么gradle不打印属性文件？

我试图从gradle产出/ Groovy中执行简单的print语句，但我得到的错误为什么gradle不打印属性文件？

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

ext.appVersion=extProgram['version'] 

println ext.appVersion

这是错误我得到

这是因为extProgram被假定为一个属性该项目。试试这个：

def extProgram = new Properties() 
...

这extProgram定义为一个局部变量。

我希望它是项目的属性，所以我可以在不同的任务中使用它。 –

在这种情况下使用：'ext.extProgram = ...' – Henry
