gradle testCompile不解析依赖项

Question

我的小gradle项目如下：

buildscript {
    ext {
        springBootVersion = '1.3.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}") 
    }
}

apply plugin: 'java'
apply plugin: 'spring-boot' 

jar {
    baseName = 'web'
    version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-actuator-docs')
    compile('org.springframework.boot:spring-boot-starter-amqp')
    compile('org.springframework.boot:spring-boot-starter-cache')
    compile('org.springframework.cloud:spring-cloud-starter-oauth2:1.1.0.RELEASE')
    compile('org.springframework.boot:spring-boot-devtools')
    compile('org.springframework.boot:spring-boot-starter-mail')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-social-facebook')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-websocket')

    compile('org.activiti:activiti-spring-boot-starter-basic')

    compile('org.springframework.boot:spring-boot-starter-data-mongodb')
    compile('org.activiti:activiti-spring-boot-starter-basic:5.19.0')

    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    runtime('mysql:mysql-connector-java')

    testCompile('junit:junit:4.12') 
    testCompile("org.springframework.boot:spring-boot-starter-test:1.3.5.RELEASE")
    testCompile('org.springframework:spring-test')
}

在完整构建期间，我遇到以下错误：

.gradle缓存中的这个奇怪我可以看到spring-boot-starter-test-1.3.5.RELEASE.jar - 但是这个文件不包含任何类。
