gradle - 在Gradle中将扩展变量用于插件版本

Question

我试图在Gradle中使用扩展变量来配置插件的版本，但是在gradle中的apply from: versions.gradle块之前无法使用plugins。

这可能吗？

我想做的事的例子。
versions.gradle:

ext.libraries = [
    plugins: [
        coveralls: 'com.github.kt3k.coveralls'
    ]
]

build.gradle

buildscript {
    repositories{}
    dependencies{}
}

plugins {
    id libraries.plugins.coveralls versions 'versionhere'
}

Answer 1

你做不到

在Gradle构建脚本中，将带有plugins DSL的插件应用声明为作为第一个语句。此行为是强制性的。

您可以检查official guide:

The plugins {} block must also be a top level statement in the buildscript. It cannot be nested inside another construct (e.g. an if-statement or for-loop)

This requires that plugins be specified in a way that Gradle can easily and quickly extract, before executing the rest of the build script.
