Gradle configuration for multi-module project with shared dependencies
提问by Aliaksei Lithium
Make a first project with gradle, so i look at spring, gradle, hibernate projects how they organize gradle files, and start make my own. But, can't find mistake, why my configuration doesn't work. (sub-projects cant resolve dependency) So project tree:
使用 gradle 创建第一个项目，所以我查看了 spring、gradle、hibernate 项目如何组织 gradle 文件，然后开始制作我自己的项目。但是，找不到错误，为什么我的配置不起作用。（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'
The problem, when i make foobar-system-jpa.gradle file with set of dependences, etc, it's not work - no dependecies can be reach for this module. But when in root 'foobar' build.gradle make a set of deps for 'foobar-system-jpa' subproject - it' work fine. Why?
问题是，当我使用一组依赖项等制作 foobar-system-jpa.gradle 文件时，它不起作用 - 此模块无法访问任何依赖项。但是当在 root 'foobar' build.gradle 中为 'foobar-system-jpa' 子项目创建一组 deps - 它'工作正常。为什么？
My root build.gradle:
我的根build.gradle：
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'
}
}
my dependecies.gradle
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:$hibernateVersion",
hibernate_persistence: "org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1.Final",
//database
postgresql : "org.postgresql:postgresql:9.3-1100-jdbc41",
commons_dbcp : "commons-dbcp:commons-dbcp:1.4",
.....
]
}
and my settings.gradle
和我的settings.gradle
rootProject.name = 'foobar'
include ':foobar-system:foobar-system-jpa'
....
include ':foobar-app:people:people-rest'
include ':foobar-app:people:people-core'
....
include ':foobar-starter'
project(':foobar-system:foobar-system-jpa').projectDir = "$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()
}
So, foobar-system-jpa.gradle that NOT work(module can not compile, cause not found any dependency)
因此， foobar-system-jpa.gradle不起作用（模块无法编译，导致未找到任何依赖项）
dependencies {
compile libs.spring_orm
compile (libs.spring_data_jpa) {
exclude(module: 'spring-jdbc')
exclude(module: 'spring-orm')
}
compile libs.hibernate_entitymanager
compile libs.postgresql
compile libs.commons_dbcp
compile project(':foobar-system:foobar-system-tx')
}
Thank you for reply. For inspiration a take a look for this project https://github.com/hibernate/hibernate-orm/blob/master/hibernate-entitymanager/hibernate-entitymanager.gradle
谢谢你的回复。如需灵感，请查看此项目https://github.com/hibernate/hibernate-orm/blob/master/hibernate-entitymanager/hibernate-entitymanager.gradle

There is a problem with your settings.gradle. It is configuring buildFileNamefor rootProject.children, which are the immediatechildren of the root project. As a result, all build scripts for projects that are more than one level deep will go unnoticed.
您的settings.gradle. 它正在配置buildFileNamefor rootProject.children，它们是根项目的直接子项。因此，所有深度超过一层的项目的构建脚本都不会被注意到。
To solve this problem, you can either set build script names explicitly, or write a method that sets them recursively.
要解决此问题，您可以显式设置构建脚本名称，也可以编写递归设置它们的方法。
