我正在通过gradle（3.2）多项目挖掘春季启动1.4.2.RELEASE on MACos Sierra 10.12.1。
这是github上的项目： https://github.com/isian8814/demospring.git
这是我的项目结构：
Root project 'demospring'
+--- Project ':model'
\--- Project ':rest'
这是root项目的build.gradle：
buildscript {
ext.springBootVersion = '1.4.2.RELEASE'
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:$springBootVersion")
}
}
allprojects {
group 'com.springboot.demo'
version '1.0-SNAPSHOT'
}
subprojects {
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
sourceCompatibility = 1.8
targetCompatibility = 1.8
compileJava.options.encoding = 'UTF-8'
dependencies {
testCompile('org.springframework.boot:spring-boot-starter-test')
}
springBoot {
mainClass = 'bookmarks.Application'
}
repositories {
mavenCentral()
}
}
task wrapper(type: Wrapper) {
gradleVersion = '3.2'
}
这是rest项目的build.gradle：
dependencies {
compile project(':model')
compile('org.springframework.boot:spring-boot-starter-web')
}
这是模型项目的build.gradle：
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-web')
runtime('com.h2database:h2')
}
这是我的settings.gradle：
rootProject.name='demospring'
include 'model'
include 'rest'
我可以运行./gradlew：model：build和./gradlew：rest：build
./gradlew :rest:build
:model:compileJava UP-TO-DATE
:model:processResources UP-TO-DATE
:model:classes UP-TO-DATE

Note: Recompile with -Xlint:unchecked for details.

有什么想法吗？
感谢。
答案 0 :(得分：0)
我认为休息项目也应该有dependencies部分，而不是restdependencies。
正如@Stanislav所提到的，你应该在根目录中有settings.gradle个文件包含这个内容：
include 'module'
include 'rest'
include 'demospring'
如果您有兴趣，这是我的Github repository with working Spring Boot multimodule project。
BTW，该repo还具有所有子模块的测试覆盖率聚合。 Here is blog post belonging to that repository。
