java - 使用 Gradle 的 Spring Boot 项目不运行 spring

Question

我正在使用 Ubuntu、IntelliJ 和 Gradle 4.8.1

一旦项目创建，如果我尝试调试它，Gradle Daemon 就会启动，构建项目最终不会运行 spring boot

我的 Gradle 属性是:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.8.1-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

控制台日志是:

8:32:06: Executing task...

Starting Gradle Daemon...
Connected to the target VM, address: '127.0.0.1:39247', transport: 'socket'
Gradle Daemon started in 5 s 356 ms

> Task :help

Welcome to Gradle 4.8.1.

To run a build, run gradle <task> ...

To see a list of available tasks, run gradle tasks

To see a list of command-line options, run gradle --help

To see more detail about a task, run gradle help --task <task>

BUILD SUCCESSFUL in 17s
1 actionable task: 1 executed
8:32:23: Task execution finished.
Disconnected from the target VM, address: '127.0.0.1:39247', transport: 'socket'

这就是我的 build.gradle 的样子:

plugins {
    id 'org.springframework.boot' version '2.2.0.RELEASE'
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'
    id 'java'
}

group = 'com.ITAcademy'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compileOnly 'org.projectlombok:lombok'
    runtimeOnly 'mysql:mysql-connector-java'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation('org.springframework.boot:spring-boot-starter-test')/* {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine' //ojo que en 2.1.9 esto no sale
    }
}

test {
    useJUnitPlatform()*/
}

谢谢

鉴于 Gradle 输出表明 :help 任务已运行，即根项目上的 help 任务，问题很可能是您没有执行指定要运行的任务。

• 您可以将要运行的任务添加到命令行或 IntelliJ 配置中。对于 Spring boot 项目，它很可能类似于 bootRun。
• 您可以define the default task in your project

请不要在 Gradle 中使用 clean，这会无缘无故地减慢构建速度，因为增量构建是 Gradle 功能的核心。
