Gradlew构建无法正常工作

当我尝试使用其清理项目时，./gradlew clean该项目./gradlew build将无法正常工作。我尝试了一些存储库，但无法解决Spring依赖项。

这是build.gradle：

apply plugin: 'war'

war {
    baseName = 'hello'
}

configurations {
    providedRuntime
}

dependencies {

    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.json:json:20141113')
    compile('com.jayway.jsonpath:json-path:0.8.1')
    compile('org.jsoup:jsoup:1.8.2')
    compile('org.springframework.social:spring-social-twitter')
    compile('org.springframework.social:spring-social-twitter:1.1.0.RELEASE')
    compile('org.springframework.social:spring-social-core')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

repositories {
        mavenCentral()
}

这里是例外：

* What went wrong:
Could not resolve all dependencies for configuration ':compile'.

我认为行家回购是足够的，但它一直失败，我也尝试过jcenter()。我正在使用Ubuntu 14.04 VM。

解决了：

正如Michael在评论中所说，我必须为依赖项添加一个版本：

compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-web:1.3.3.RELEASE')
