spring - Gradlew 构建不起作用

Question

当我尝试使用 ./gradlew clean 清理我的项目时它有效，但是./gradlew build不会工作。我尝试了一些存储库，但它无法解决 Spring 依赖项。

这里是 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()
}

这里有一个异常(exception):

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

我认为 maven repo 就足够了，但它一直失败我也尝试过 jcenter() .我正在使用 ubuntu 14.04 虚拟机。

已解决:

正如迈克尔在评论中所说，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')

Answer 1

首先，在依赖项之前声明存储库。其次，更换

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

和

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

因为前者不包含版本。
