我正在尝试使用gradle工具构建RESTful WebService项目。但是构建失败了。控制台提供以下输出。
C:\Users\bob\Downloads\gs-rest-service-master\gs-rest-service-master\complete>gradle build
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring root project 'complete'.
> Could not resolve all dependencies for configuration ':classpath'.
> Could not resolve org.springframework.boot:spring-boot-gradle-plugin:1.0.0.RC4.
Required by:
:complete:unspecified
> Could not GET 'http://repo.spring.io/libs-snapshot/org/springframework/boot/spring- boot-gradle-plugin/1.0.0.RC4/spring-boot-gradle-plugin-1.0.0.RC4.pom'.
> Connection to http://repo.spring.io refused
> java.lang.NullPointerException (no error message)
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
当我发出命令时
gradle build --stacktrace
获取以下stacktrace：
Caused by: org.gradle.api.internal.artifacts.ivyservice.ModuleVersionResolveException: Could not resolve org.springframework.boot:spring-boot-gradle-plugin:1.0.0.RC4.

以下是我的Build.gradle文件的内容
buildscript {
repositories {
maven { url "http://repo.spring.io/libs-snapshot" }
mavenLocal()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.0.0.RC4")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
repositories {
mavenCentral()
maven { url "http://repo.spring.io/libs-snapshot" }
}
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
compile("com.fasterxml.jackson.core:jackson-databind")
testCompile("junit:junit")
}
jar {
baseName = 'gs-rest-service'
version = '0.1.0'
}
task wrapper(type: Wrapper) {
gradleVersion = '1.11'
}
请帮我解释为什么构建失败？这与代理设置有什么关系吗？
