构建失败 Spring 未找到引导插件

Question

我从 spring.io 下载了一个 repo 'gs-handling-form-submission'，现在我正在尝试构建： gradle build

已触发跟随错误

 * Where:
Build file 'C:\Users\Username\Desktop\gs-handling-form-submission\complete\build.gradle' line: 11

* What went wrong:
Plugin [id: 'org.springframework.boot', version: '2.4.2'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.springframework.boot:org.springframework.boot.gradle.plugin:2.4.2')
  Searched in the following repositories:
    Gradle Central Plugin Repository

我已经添加了一个 repo url，更改了 spring.boot 版本，在第一行添加了buildscript.repositories() ，即使这样做，我也无法编译。

plugins {
    id 'org.springframework.boot' version '2.4.2'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

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

repositories {
    jcenter()
    mavenCentral()
    maven {
        url: "https://plugins.gradle.org/m2/"
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

Answer 1

修复build.gradle ，删除: url，可以构建

plugins {
    id 'org.springframework.boot' version '2.6.3'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

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

repositories {
    jcenter()
    mavenCentral()
    maven {
        url 'https://plugins.gradle.org/m2/'
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}
