解决 gradle 拥有的项目依赖关系

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：

1. ProjectCommonUtil -> 无
2. ProjectWeb -> a、c、d
3. ProjectBatchUtil -> 无
4. ProjectHttpClientUtil -> 一个
5. ProjectBatchWithMainClass -> b, c, d(a)

不用担心开源依赖，这就是我正在努力解决的问题：

1. 能够单独构建每个项目

   1. 依赖关系应该在 lib 文件夹 jars 中确定

      1. 如果缺少依赖jar，构建依赖并cc:jar到lib文件夹

         例如：d 取决于 a。 a 的 jar 不在 lib 文件夹中，所以构建一个然后放在 lib 文件夹中，然后构建 d

         这些是我在下面提供的包含的 build.gradle 文件

2. 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 jars a、c、d。项目网

我无法在根项目和现有项目之间创建 gradle 多项目，也无法创建胖 jar。也许我正在尝试对 gradle 进行微观管理，但这个 #2 是我需要的，因为我需要将 web ear 部署到应用服务器和批处理（e.），并且它依赖于多个位置的多个运行 e 变体的 linux VM。使用不同的 JVM 参数。

帮助！

Answer 1

如果你稍微修改你的设置，你肯定是在与 Gradle 作斗争，并且必须补偿它会为你处理的事情。

多项目定义可以完美地与它聚合的项目处于同一级别。只需添加一个带有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'

然后您可以表达项目之间的依赖关系，将执行必要副本的打包任务添加到 lib 文件夹等......

Answer 2

includeFlat 可能是 Louis 建议的另一种选择。这就是我解决问题的方法。

ArcGradle ProjectCommon lib\ArcProjectJars

ArcGradle settings.gradle
rootProject.name = 'ArcGradle' include ':ProjectCommon' project(':ProjectCommon').projectDir = file('../ProjectCommon')

ArcGradle build.gradle

subprojects {
    // +++++++++++++++++++++ ORDER IS IMPORTANT ++++++++++++++++
    apply plugin: 'java'
    group "com.mmm.arc"
    version =  '2.5.0'
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
    build.dependsOn('copyProjectJar')
    clean.dependsOn('deleteProjectJar')

    // In this section you declare where to find the dependencies of your project
    repositories {
        // Use 'jcenter' for resolving your dependencies.
        // You can declare any Maven/Ivy/file repository here.
        jcenter()
    }

    ext {
        arcProjectJarDir = "${rootDir}${File.separator}CommonJars${File.separator}ArcProjectJars"
    } 

    tasks.create(name: 'copyProjectJar', type: Copy) {
        into "${arcProjectJarDir}"
            from "/build/libs"
            include "*.jar"
    }   
    copyProjectJar.doFirst { 
        println "${project.name}:In copyProjectJar:BEGIN" 
    }
    copyProjectJar.doLast { println 'In copyProjectJar:END' }
    copyProjectJar.dependsOn('jar','deleteProjectJar')
    tasks.create(name: 'deleteProjectJar', type:Delete) {
        // Remove existing jars only if build is necessary
        delete fileTree(dir: "${arcProjectJarDir}", include: "${project.name}*.jar")
    }
}

而我的 ArcCommon settings.gradle 是空的，build.gradle 只包含依赖项{}

我可以将 rootProject.name = 'ArcCommon' 添加到 settings.gradle 但它是从文件夹名称推断出来的
