无法解析外部依赖项org.springframework.boot：spring-boot-starter：因为未定义存储库

Question

我有multibuild项目，目前正在设置。每个模块自然都有一个gradle.build仅包含以下内容的文件：

dependencies {

}

在build.gradle我想要的主文件中，每个模块都需要。但是当我做一个gradle build我得到一个错误说：

无法解析外部依赖项org.springframework.boot：spring-boot-starter：，因为未定义存储库。要求：项目：

apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'io.spring.dependency-management'

version = '0.0.1-SNAPSHOT'
    sourceCompatibility = 1.8

buildscript {
    ext {
        springBootVersion = '2.0.0.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {

        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

sourceSets.all { ext.purpose = null }

// Everything in subprojects are applied to all modules
subprojects {

    apply plugin: 'java'
    apply plugin: 'maven'
    apply plugin: 'eclipse'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'

    version = '0.0.1-SNAPSHOT'


    test {
        useTestNG()
        testLogging.showStandardStreams = true

        beforeTest { descriptor ->
            logger.lifecycle("Running test: " + descriptor)
        }

        // listen to standard out and standard error of the test JVM(s)
        onOutput { descriptor, event ->
            logger.lifecycle("Test: " + descriptor + " produced standard out/err: " + event.message )
        }
    }

    tasks.withType(JavaCompile) {
        options.encoding = 'UTF-8'
    }

    repositories {
        jcenter()
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }

    dependencies {
        compile('org.springframework.boot:spring-boot-starter')
        testCompile('org.springframework.boot:spring-boot-starter-test')
    }

}

dependencies {
    compile('org.springframework.boot:spring-boot-starter')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

忠告

Answer 1

您只为子项目定义了存储库，但是您也必须在根项目中定义它，因为dependencies那里有一个块：

dependencies {
    compile('org.springframework.boot:spring-boot-starter')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

在您的情况下，您可以通过repositories在subprojects闭包中再次声明来做到这一点：

repositories {
    jcenter()
    mavenCentral()
    maven {
        url "https://plugins.gradle.org/m2/"
    }
}

subprojects {
   ...
}

或者您可以为所有项目定义它：

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
}

在这种情况下，您不需要o在subprojects结束时声明它
