Question

项目结构：

root
-- 0. CAN'T add multi-project here
----\ a. ProjectCommonUtil
----\ b. ProjectWeb
----\ c. ProjectBatchUtil
----\ d. ProjectHttpClientUtil
----\ e. ProjectBatchWithMainClass
----\ lib

依赖关系：

ProjectCommonUtil - ＆gt;无
ProjectWeb - ＆gt; a，c，d
ProjectBatchUtil - ＆gt;无
ProjectHttpClientUtil - ＆gt;一个
ProjectBatchWithMainClass - ＆gt; b，c，d（a）

不用担心开源依赖关系，这就是我正在努力解决的问题：

能够单独构建每个项目
1. 应在lib文件夹jar中确定依赖关系
  1. 如果缺少依赖jar，则构建依赖关系并将cc：jar转换为lib文件夹
    
    Ex：d取决于a。 a的jar不在lib文件夹中，所以在lib文件夹中构建一个然后放置，然后构建d
    
    这些是我在下面提供的build.gradle文件
上述结构中的lib文件夹包含
1. a，b的罐子（是的，以罐子形式b / c的e），c，d，e
2. b的Ear文件。 ProjectWeb，在b中相应的WEB-INF / lib文件夹中包含jar a，c，d。 ProjectWeb

我无法在root和现有项目之间创建一个gradle多项目，我无法创建胖罐。也许我正在尝试微观管理gradle但这个＃2是我需要的，因为我需要将web ear部署到app服务器和批处理（e。），并且它依赖于运行e变体的多个位置的几个linux VM。使用不同的JVM args。

帮助！

TIA，比尔

Answer 1

如果你稍微修改一下设置，你肯定会和Gradle打架，不得不赔偿它会为你处理的事情。

多项目定义可以完美地与其聚合的项目处于同一级别。只需添加一个包含build.gradle和settings.gradle的新目录，并引用您需要集成的不同模块：

    includeFlat 'a'
    includeFlat 'b'
    includeFlat 'c'
    includeFlat 'd'
    includeFlat 'e'

然后你可以表达项目之间的依赖关系，添加执行必要副本的打包任务到lib文件夹等......

Answer 2

如路易斯建议的那样，includeFlat可能是另一种选择。这就是我解决问题的方法。

        // You can declare any Maven/Ivy/file repository here.
        jcenter()
    }

    ext {

    tasks.create(name: 'copyProjectJar', type: Copy) {
        into "${arcProjectJarDir}"
            from "/build/libs"
            include "*.jar"

    copyProjectJar.doFirst {

        // Remove existing jars only if build is necessary
        delete fileTree(dir: "${arcProjectJarDir}", include: "${project.name}*.jar")
    }
}

我的ArcCommon settings.gradle为空，build.gradle只包含依赖项{}

我可以将rootProject.name = 'ArcCommon'添加到settings.gradle，但是从文件夹名称中推断出
