Java 具有共享依赖项的多模块项目的梯度配置

用gradle做第一个项目，我看看spring、gradle、hibernate项目是如何组织gradle文件的，然后开始做我自己的。但是，找不到错误，为什么我的配置不工作。（子项目无法解决依赖关系） 所以项目树：

Root project 'foobar'
+--- Project ':foobar-app'
| +--- Project ':foobar-app:people'
| | +--- Project ':foobar-app:people:people-api'
| | +--- Project ':foobar-app:people:people-core'
| | +--- Project ':foobar-app:people:people-data'
| | \--- Project ':foobar-app:people:people-rest'
| \--- Project ':foobar-app:realtor'
+--- Project ':foobar-starter'
\--- Project ':foobar-system'
+--- Project ':foobar-system:foobar-system-jpa'
+--- Project ':foobar-system:foobar-system-neo4j'
+--- Project ':foobar-system:foobar-system-persistence'
+--- Project ':foobar-system:foobar-system-repository'
\--- Project ':foobar-system:foobar-system-tx'

configurations.all {
    // check for updates every build
    resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}

configure(allprojects) { project ->
    group = 'com.foobar'
    version = '0.0.1-SNAPSHOT'

    apply from: "${rootDir}/dependencies.gradle"

    apply plugin: 'maven'
    apply plugin: 'idea'

    ext.gradleScriptDir = "${rootProject.projectDir}/gradle"

    apply from: "${gradleScriptDir}/task.gradle"

}

configure(subprojects) { subproject ->
    apply plugin: 'java'

    sourceCompatibility = 1.7
    targetCompatibility = 1.7
    apply from: "${rootDir}/dependencies.gradle"

    repositories {
        mavenCentral()

        maven { url "http://m2.neo4j.org/" }
        maven { url "http://repo.maven.apache.org/maven2" }
    }


    dependencies {
        testCompile (libs.junit)
        testCompile (libs.mockito)
        testCompile group: 'org.hamcrest', name: 'hamcrest-library', version: '1.3'
    }

}

问题是，当我使用一组依赖项等创建foobar-system-jpa.gradle文件时，它不起作用-此模块无法访问任何依赖项。但是，在根“foobar”build.gradle中，为“foobar系统jpa”子项目创建一组DEP—它可以正常工作。为什么?

我的根构建。gradle：

Root project 'foobar'
+--- Project ':foobar-app'
| +--- Project ':foobar-app:people'
| | +--- Project ':foobar-app:people:people-api'
| | +--- Project ':foobar-app:people:people-core'
| | +--- Project ':foobar-app:people:people-data'
| | \--- Project ':foobar-app:people:people-rest'
| \--- Project ':foobar-app:realtor'
+--- Project ':foobar-starter'
\--- Project ':foobar-system'
+--- Project ':foobar-system:foobar-system-jpa'
+--- Project ':foobar-system:foobar-system-neo4j'
+--- Project ':foobar-system:foobar-system-persistence'
+--- Project ':foobar-system:foobar-system-repository'
\--- Project ':foobar-system:foobar-system-tx'

configurations.all {
    // check for updates every build
    resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}

configure(allprojects) { project ->
    group = 'com.foobar'
    version = '0.0.1-SNAPSHOT'

    apply from: "${rootDir}/dependencies.gradle"

    apply plugin: 'maven'
    apply plugin: 'idea'

    ext.gradleScriptDir = "${rootProject.projectDir}/gradle"

    apply from: "${gradleScriptDir}/task.gradle"

}

configure(subprojects) { subproject ->
    apply plugin: 'java'

    sourceCompatibility = 1.7
    targetCompatibility = 1.7
    apply from: "${rootDir}/dependencies.gradle"

    repositories {
        mavenCentral()

        maven { url "http://m2.neo4j.org/" }
        maven { url "http://repo.maven.apache.org/maven2" }
    }


    dependencies {
        testCompile (libs.junit)
        testCompile (libs.mockito)
        testCompile group: 'org.hamcrest', name: 'hamcrest-library', version: '1.3'
    }

}

我的依赖。gradle

ext {
    springVersion = "4.0.0.RELEASE"
    jUnitVersion = "4.11"
    hibernateVersion = "4.2.1.Final"

    libs = [
            //springframework
            spring_core: "org.springframework:spring-core:$springVersion",
            spring_orm: "org.springframework:spring-orm:$springVersion",
          ......
            hibernate_entitymanager: "org.hibernate:hibernate-entitymanager:$hibernateVersion",
            hibernate_persistence: "org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1.Final",
            //database
            postgresql : "org.postgresql:postgresql:9.3-1100-jdbc41",
            commons_dbcp : "commons-dbcp:commons-dbcp:1.4",
           .....

    ]
}

和我的设置。gradle

rootProject.name = 'foobar'
include ':foobar-system:foobar-system-jpa'
....
include ':foobar-app:people:people-rest'
include ':foobar-app:people:people-core'
....
include ':foobar-starter'

project(':foobar-system:foobar-system-jpa').projectDir = "$rootDir/foobar-system/foobar-system-jpa" as File
project(':foobar-system:foobar-system-repository').projectDir = "$rootDir/foobar-system/foobar-system-repository" as File
.....
project(':foobar-app').projectDir = "$rootDir/foobar-app" as File
project(':foobar-starter').projectDir = "$rootDir/foobar-starter" as File

rootProject.children.each { project ->
    project.buildFileName = "${project.name}.gradle"
    assert project.projectDir.isDirectory()
    assert project.buildFile.exists()
    assert project.buildFile.isFile()
}

所以，foobar-system-jpa.gradle不起作用（模块无法编译，导致找不到任何依赖项）

谢谢你的回复。要获得灵感，请看一下这个项目

UPD：删除一些不必要的代码您的

设置有问题。gradle

。它正在为根项目的直接子项目

rootProject.children

配置

buildFileName

。因此，对于深度超过一级的项目，所有构建脚本都将被忽略

要解决此问题，可以显式设置生成脚本名称，也可以编写递归设置它们的方法

附言：总是尝试提出一个最小的失败例子，而不是张贴代码页

您收到的错误消息是什么？@JBaruch没有错误，但我编译foobar system jpa时似乎没有找到任何依赖项。谢谢，这是真正的工作。我尝试使用完整路径，比如：

project（“：foobar-app:people:people-core”）.buildFileName=“$rootDir/foobar-app/people/people-core.gradle”

，但它不起作用，所以当我现在只输入构建文件的名称时，它起作用了<代码>项目（“”）=“people core.gradle”哇，对我来说这并不明显。
