Gradle 无法解析 org.springframework.boot：spring-boot-gradle-plugin：1.4.2.RELEASE （repo1.maven.org： Nome o servizio sconosciuto）

我在 Jenkins 上运行 gradle 构建时遇到问题：Gradle 版本 https://services.gradle.org/distributions/gradle-2.14.1-bin.zip

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'myApp'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve org.springframework.boot:spring-boot-gradle-plugin:1.4.2.RELEASE.
     Required by:
         :myApp:unspecified
      > Could not resolve org.springframework.boot:spring-boot-gradle-plugin:1.4.2.RELEASE.
         > Could not get resource 'https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-gradle-plugin/1.4.2.RELEASE/spring-boot-gradle-plugin-1.4.2.RELEASE.pom'.
            > Could not HEAD 'https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-gradle-plugin/1.4.2.RELEASE/spring-boot-gradle-plugin-1.4.2.RELEASE.pom'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

这是我的 build.gradle 文件：

buildscript {
    ext {
        springBootVersion = '1.4.2.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse-wtp'
apply plugin: 'org.springframework.boot'
apply plugin: 'war'


war {
    baseName = 'myApp'
    version = '1.0.5'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}

configurations {
    providedRuntime
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    compile('org.springframework.boot:spring-boot-starter-security')
