带有Gradle的Spring Boot多模块项目无法构建
2022-09-01 07:09:10
我正在开发一个具有多个模块的Spring Boot应用程序,我们正在使用Gradle来构建它。不幸的是,我无法正确设置Gradle配置。
项目结构如下:
parent
|
+ build.gradle
|
+ settings.gradle
|
+ core
| |
| + build.gradle
|
+ apis
| |
| + build.gradle
|
+ services
| |
| + build.gradle
|
+ data
| |
| + build.gradle
当我尝试构建项目时,我收到编译错误,例如说,服务中使用的数据中的类未导入。我假设在所有模块之间都是如此。error: cannot find symbol
我的父级 build.gradle 看起来像这样:
buildscript {
ext {
springBootVersion = '2.0.0.BUILD-SNAPSHOT'
}
repositories {
mavenCentral()
maven { url "https://repo.spring.io/snapshot" }
maven { url "https://repo.spring.io/milestone" }
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'eclipse'
apply plugin: 'idea'
allprojects {
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
maven { url "https://repo.spring.io/snapshot" }
maven { url "https://repo.spring.io/milestone" }
}
dependencies {
testCompile('org.springframework.boot:spring-boot-starter-test')
}
}
dependencies {
compile project(':data')
compile project(':services')
compile project(':apis')
compile project(':core')
}
jar {
baseName = 'my-jar'
version = '0.0.1-SNAPSHOT'
}
settings.gradle:
rootProject.name = 'my-app'
include ':apis'
include ':core'
include ':data'
include ':services'
其中一个孩子(核心)在它的build.gradle中有这个:
dependencies {
compile('org.springframework.boot:spring-boot-starter-actuator')
compile('org.springframework.boot:spring-boot-starter-quartz')
compile('org.springframework.boot:spring-boot-starter-tomcat')
runtime('com.h2database:h2')
compile project(':data')
compile project(':services')
compile project(':apis')
}
services build.gradle 看起来像这样:
dependencies {
compile('org.springframework.boot:spring-boot-starter-quartz')
compile('org.springframework.boot:spring-boot-starter-data-jpa')
runtime('com.h2database:h2')
compile project(':data')
}
其他的也只声明依赖项。
依赖关系结构如下所示:
core - apis, services, data
apis - services, data
services - data
data -
编译错误示例:
/my-app/services/src/main/java/com/example/my-app/business/IssuedTokenService.java:3: error: package com.examples.data.dao does not exist import com.examples.data.dao.IssuedToken;
