Gradle：列出junit#junit的版本时出错；4.+；

在gradle.properties文件上运行

gradle build

时，我遇到以下错误

我知道我在防火墙后面，我有一个可以使用的poxy。我已经尝试将下面的内容添加到gradle.properties文件中，但是我无法下拉jUnit。感谢大家的帮助

systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080

错误：

Error listing versions of junit#junit;4.+ using class 
org.gradle.api.internal.artifacts.repositories.resolver.MavenVersionLister$1. 
Will attempt an alternate way to list versions. This behaviour has been 
deprecated and is scheduled to be removed in Gradle 2.0

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':testRuntime'.
> Could not resolve junit:junit:4.+.
  Required by:
      :HealthMonitor:1.0
   > Failed to list versions for junit#junit;4.+.

         > Could not GET 'http://repo1.maven.org/maven2/junit/junit/'.

build.gradle：

apply plugin: 'java'
apply plugin: 'eclipse'

version = '1.0'
jar {
    manifest {
        attributes 'Implementation-Title': 'Health Monitor', 'Implementation-Version': version
    }
}

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.+'
}

根据代理的不同，您可能需要配置的不仅仅是主机和端口。请参见《Gradle用户指南》中的。此外，我建议尝试使用固定版本，而不是版本范围
