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

Question

我在Jenkins上运行gradle构建时遇到问题:Gradle版本是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'.
               > repo1.maven.org: Nome o servizio sconosciuto

* 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')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('com.fasterxml.jackson.core:jackson-core:2.7.3')
    compile("org.springframework:spring-jdbc")
    compile('com.fasterxml.jackson.core:jackson-databind:2.7.3')
    compile('com.fasterxml.jackson.core:jackson-annotations:2.7.3')
    compile files('src/main/resources/static/lib/ojdbc7.jar')
    // https://mvnrepository.com/artifact/org.json/json
    compile group: 'org.json', name: 'json', version: '20080701'

}

Answer 1

由于错误告诉您Nome o servizio sconosciuto,repo1.maven.org无法通过DNS解决.因此,您遇到了一些网络问题,或者您需要使用未配置Gradle的代理服务器.询问您的IT支持,了解无法解析主机名的原因.

Answer 2

当我尝试使用 gradle 3.5 使用我的笔记本电脑（无需代理）首次在 IntelliJ 上运行 gradle 时，出现了 spring-boot-starter 依赖项无法解决的问题。

问题被遗漏了：

apply plugin: 'org.springframework.boot'

来自 build.gradle 文件。一旦包含，它就会立即下载所有依赖项。

Answer 3

这可能是网络问题。如果没有，请尝试以下步骤，因为它解决了我的问题。

由于我也面临同样的问题，我尝试通过更改依赖项来解决它。

这个值给了我一个错误。

compile("org.springframework.boot:spring-boot-starter-ws") 

这是有效的

compile group: 'org.springframework.boot', name: 'spring-boot-starter-ws', version: '1.4.7.RELEASE'
