我有一个monolythic build.gradle来构建一个应用程序。它由几个任务组成（缩小，组合文件，gzip，上传到CDN，调用外部脚本等）
我设法将build.gradle中的所有内容移到buildsrc/中的自定义插件中，遵循文档中的GreetingPlugin官方Gradle教程。经过一番努力，我现在可以从build.gradle成功调用它，并且它按预期工作：
group 'CDN'
version '1.0-SNAPSHOT'
buildscript {
.
.
}
println "building user app"
apply plugin: BuildAppModule
appmodulebuilder.modulename = 'user'
到目前为止一切顺利。但我将所有内容移到buildsrc /中的插件的目的是能够多次调用此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'
和这个
task buildUser {
println "building user app"
apply plugin: BuildAppModule
appmodulebuilder.modulename = 'user'
}
task buildAdmin {
println "building admin app"
apply plugin: BuildAppModule
appmodulebuilder.modulename = 'admin'
}
和这个
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'
}
}
和这个
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'
}
}
然而，该插件永远不会被执行2次。我最接近的是，插件使用最后提供的值执行一次。
任何人都可以在没有＆＃34的情况下帮助我;阅读gradle文档的插件部分＆＃34; - 有点回答？ （我有，但发现对于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。buildSrc /主/常规/ BuildAppModule.groovy

插件只能应用于项目一次。任何尝试在第二次或以后的时间应用相同的插件都将无效。
我觉得你的插件应该添加一个extension object，可以在应用插件后进行配置。
例如：
apply plugin: BuildAppModule
appModuleBuilder {
moduleNames = ['user', 'admin']
}
或者
apply plugin: BuildAppModule
appModuleBuilder {
module {
name = 'user'
type = 'xxx'
}
module {
name = 'admin'
type = 'yyy'
}
}
