gradle - 在 buildsrc/中多次调用我的插件

Question

我有一个单一的build.gradle构建一个应用程序。它由几个任务组成(缩小、合并文件、gzip、上传到 CDN、调用外部脚本等)

我设法将所有内容移至 build.gradle到 buildsrc/ 中的自定义插件，遵循文档中 GreetingPlugin 的官方 Gradle 教程。经过一番努力，我现在可以从build.gradle成功调用它了。 amd 它按预期工作:

group 'CDN'
version '1.0-SNAPSHOT'

buildscript {
    .
    .
}

println "building user app"
apply plugin: BuildAppModule
appmodulebuilder.modulename = 'user'

到现在为止还挺好。但我将所有内容移至 buildsrc/中的插件的目的是能够多次调用该插件来构建不同的模块。

天真地，我试过这个:

.
.
println "building user app"
apply plugin: BuildAppModule
appmodulebuilder.modulename = 'user'

println "building admin app"
apply plugin: BuildAppModule
appmodulebuilder.modulename = 'admin'

还有这个

task buildUser {
    println "building user app"
    apply plugin: BuildAppModule
    appmodulebuilder.modulename = 'user'
}
task buildAdmin {
    println "building admin app"
    apply plugin: BuildAppModule
    appmodulebuilder.modulename = 'admin'
}

还有这个

task buildUser {
    doLast {
        println "building user app"
        apply plugin: BuildAppModule
        appmodulebuilder.modulename = 'user'
    }
}
task buildAdmin {
    doLast {
        println "building admin app"
        apply plugin: BuildAppModule
        appmodulebuilder.modulename = 'admin'
    }
}

还有这个

  apply plugin: BuildAppModule
  task buildUser (Type: BuildAppModule) {
        doLast {
            println "building user app"
            appmodulebuilder.modulename = 'user'
        }
    }
    task buildAdmin (Type: BuildAppModule) {
        doLast {
            println "building admin app"
            appmodulebuilder.modulename = 'admin'
        }
    }

但是插件永远不会执行 2 次。我最接近的一次，插件使用最后提供的值执行一次。

任何人都可以在没有“阅读 gradle 文档的插件部分”的情况下帮助我吗？ (我有，但发现它对于 gradle 新手来说非常难以接近!)

编辑:整个插件，我的需要是在一组目录上执行它。

一个插件只能应用于一个项目一次。任何第二次或以后应用相同插件的尝试都将无效。

我觉得你的插件应该添加一个 extension object可以在应用插件后配置。

例如:

apply plugin: BuildAppModule
appModuleBuilder {
    moduleNames = ['user', 'admin']        
}

也许

apply plugin: BuildAppModule
appModuleBuilder {
    module {
        name = 'user'
        type = 'xxx'
    }
    module {
        name = 'admin'
        type = 'yyy'
    }
}
