ext 和代码块在 gradle 文件中的含义 [英] ext and code block's meaning in the gradle file
问题描述
ext {
springVersion = "3.1.0.RELEASE"
emailNotification = "build@master.org"
}
以上代码是build.gradle的片段
Above code is the snippet of build.gradle
我知道使用 { } 闭包参数调用 ext 方法.这是正确的?所以我认为 gradle 正在访问 springVersion 和 emailNotification.我将用下面的代码验证我的假设
I understand that call ext method with { } closure parameter. it's right? So I think gradle is accessing springVersion and emailNotification. I'm gonna verify my assumption with below code
def ext(data) {
println data.springVersion
}
ext {
springVersion = "3.1.0.RELEASE"
emailNotification = "build@master.org"
}
但运行该代码发生以下错误.
but run that code below Error occured.
groovy.lang.MissingPropertyException: No such property: springVersion for class: Test
具体解释ext和代码块吗?
do you explain ext and code block specifically?
推荐答案
ext 是 project.ext 的简写，用于定义额外的属性 用于 project 对象.(也可以为许多其他对象定义额外的属性.)当读取额外的属性时，ext. 被省略(例如 println project.springVersion 或 printlnspring版本).从方法内部也是如此.声明一个名为 ext 的方法是没有意义的.
ext is shorthand for project.ext, and is used to define extra properties for the project object. (It's also possible to define extra properties for many other objects.) When reading an extra property, the ext. is omitted (e.g. println project.springVersion or println springVersion). The same works from within methods. It does not make sense to declare a method named ext.
