【问题描述】：

我的gradle.build

file for simple module is:
buildscript 
    ext 
        springBootVersion = '1.4.3.RELEASE'
    
    repositories 
        mavenCentral()
    
    dependencies 
        classpath("org.springframework.boot:spring-boot-gradle-plugin:$springBootVersion")
    


apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

jar 
    baseName = 'client-app'
    version = '0.0.1-SNAPSHOT'

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories 
    mavenCentral()



dependencies 
    compile('org.springframework.cloud:spring-cloud-starter-feign')
    // https://mvnrepository.com/artifact/com.netflix.hystrix/hystrix-core
    compile('org.springframework.cloud:spring-cloud-starter-hystrix')
    compile("org.springframework.boot:spring-boot-starter-web")
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
    
    compileOnly('org.projectlombok:lombok')
    testCompile('org.springframework.boot:spring-boot-starter-test')


dependencyManagement 
    imports 
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:Camden.BUILD-SNAPSHOT"
        mavenBom "org.springframework.boot:spring-boot-starter-parent:$springBootVersion"
    

在我关闭 IDE (Intellij IDEA 2016) 并重新打开之前，它运行良好。我收到如下错误：

Error:Cause: org.gradle.internal.component.external.model.DefaultModuleComponentSelector

当我尝试通过 cmd 运行时，出现以下错误：

$ ./gradlew build
:client-app:compileJava
FAILURE: Build failed with an exception.

我想不出解决办法。

我已经尝试过gradle build --refresh-dependencies，但对我不起作用。 TIA 寻求帮助。

【参考方案1】：

最后，我在Issue #5564 得到了解决方案。 :)

正如@wilkinson 在他对该问题的回复中提到的那样，项目依赖于 Spring Boot 的依赖管理并且版本解析失败。

所以，我明确指定版本为：

   dependencies 
    compile('org.springframework.cloud:spring-cloud-starter-feign:1.2.3.RELEASE')
    // https://mvnrepository.com/artifact/com.netflix.hystrix/hystrix-core
    compile('org.springframework.cloud:spring-cloud-starter-hystrix:1.2.3.RELEASE')
    compile("org.springframework.boot:spring-boot-starter-web:1.4.3.RELEASE")
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
    
    compileOnly('org.projectlombok:lombok:1.16.12')
    testCompile('org.springframework.boot:spring-boot-starter-test:1.4.3.RELEASE')

它对我有用。 :)
