如何在多模块项目中通过 gradle 而不是使用 JUnit5 和 SpringBoot2 的 intelliJ 进行 运行 测试
How to run tests by gradle instead of intelliJ with JUnit5 and SpringBoot2 in multi module project
我创建了一个空的 gradle 项目，里面有单个模块（子项目）也作为 gradle 项目，但是有 Spring boot 2.
主要内容（无标题 1）
build.gradle:
group 'com.example'
version '1.0-SNAPSHOT'
allprojects {
repositories {
mavenCentral()
}
}
settings.gradle:
rootProject.name = 'main-project'
include 'new-one'
子项目（new-one）：
构建 gradle:
plugins {
id("java")
id("org.springframework.boot") version "2.1.8.RELEASE"
id("io.spring.dependency-management") version "1.0.8.RELEASE"
}
group = 'com.example'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.12
dependencies {
implementation 'org.springframework.boot:spring-boot-dependencies:2.0.5.RELEASE'
implementation 'org.springframework.boot:spring-boot-starter-web'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
def junit = '5.5.2'
testImplementation ("org.junit.jupiter:junit-jupiter-api:${junit}")
testImplementation ("org.junit.jupiter:junit-jupiter-params:${junit}")
testImplementation ("org.assertj:assertj-core:3.11.1")
testRuntime("org.junit.jupiter:junit-jupiter-engine:${junit}")
}
test {
useJUnitPlatform()
}
运行 test using test 运行ner as: IntelliJ idea 编译并通过了测试，但是当我使用 gradle 它 returns 如果我 运行 单测：
