Gradle全局变量不在buildscript范围内

问题描述

我的顶级水平build.gradle(2.2级)

I have something like this in my top level build.gradle (Gradle 2.2)

ext.repo = "https://my-artifactory-repo"

buildscript {
    repositories {
        maven {
            credentials {
                username foo
                password bar
            }
            url repo //doesn't work
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.14.1'

    }
}

allprojects {
    repositories {
        maven {
            credentials {
                username foo
                password bar
            }
            url repo //works
        }
    }
}

这是错误

Could not find property 'repo' on org.gradle.api.internal.artifacts.repositories.DefaultMavenArtifactRepository_Decorated@718afa64.

因此它可以在allprojects中工作，但不能在buildscript中工作.

So it works in allprojects but not buildscript.

推荐答案

之所以发生这种情况，是因为总是首先评估buildscript {...}配置闭包，因此该属性尚未定义.一种解决方法是通过将生成的属性放置在文件中或通过命令行将其定义在生成脚本之外.

This is happening because the buildscript {...} configuration closure is always evaluated first, so the property is not yet defined. A workaround would be to define the property outside of the build script, either by placing it in a gradle.properties file or via the command line.
