当我在开发模式下停止应用程序并使用Spring启动build.gradle.kts时出错

Question

1. 我已经用https://start.spring.io/创建了一个Spring启动应用程序
2. 我有build.gradle.kts档案

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    id("org.springframework.boot") version "2.2.6.RELEASE"
    id("io.spring.dependency-management") version "1.0.9.RELEASE"
    kotlin("jvm") version "1.3.71"
    kotlin("plugin.spring") version "1.3.71"
    kotlin("plugin.jpa") version "1.3.71"
}

group = "com.warlock"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_11

repositories {
    mavenCentral()
}

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.boot:spring-boot-starter-data-rest")
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("org.springframework.boot:spring-boot-starter-security")
    implementation("org.springframework.security:spring-security-config")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    runtimeOnly("org.postgresql:postgresql")
    testImplementation("org.springframework.boot:spring-boot-starter-test") {
        exclude(group = "org.junit.vintage", module = "junit-vintage-engine")
    }
}

tasks.withType<Test> {
    useJUnitPlatform()
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "1.8"
    }
}

它显示的错误代码如下

> Task :BackendAppApplicationKt.main() FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':BackendAppApplicationKt.main()'.
> Build cancelled while executing task ':BackendAppApplicationKt.main()'
* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':BackendAppApplicationKt.main()'.

Caused by: org.gradle.api.BuildCancelledException: Build cancelled while executing task ':BackendAppApplicationKt.main()'

当您按下停止按钮时，您在外部停止/取消正在运行的任务，这是一个构建任务。如果您希望任务成功完成，您必须允许您的应用程序自行完成，即按下停止您正在取消构建，这会导致引发异常。

在你的情况下，应用程序整理并不真正适合Spring，所以基本上忽略这个消息。你可能会说，这条信息不是特别清楚，看起来像是一个错误，但事实就是这样。

区别在于任务是在外部停止（通过停止按钮取消）还是自己完成。
