Question

我是Gradle的新手，所以对此错误的任何帮助都将受到高度赞赏。

我正在使用Spring-boot构建基于REST的服务。我想将JAR文件发布到本地maven存储库，以便我的Web应用程序可以使用它。在尝试了很多东西后，我终于选择了maven-publish插件。这是我的build.gradle文件

//Needed for spring-boot
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.1.8.RELEASE")
    }
}

apply plugin: 'eclipse'

// Apply the groovy plugin to add support for Groovy
apply plugin: 'groovy'

//apply Spring-boot plugin
apply plugin: 'spring-boot'

apply plugin: 'maven-publish'

// In this section you declare where to find the dependencies of your project
repositories {
    mavenLocal()

    // Use 'jcenter' for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
    mavenCentral()
}

group = "com.proto"

publishing {
    publications {
        maven(MavenPublication) {
            groupId "${project.group}"
            artifactId "${project.name}"
            version "${project.jar.version}"
            artifact sourceJar { classifier "sources" }
            from components.java

            pom.withXml {
                asNode().appendNode('parent')
                        .appendNode('groupId', 'org.springframework.boot').parent()
                        .appendNode('artifactId', 'spring-boot-starter-parent').parent()
                        .appendNode('version', '1.1.8.RELEASE')

                asNode().appendNode('repositories').appendNode('repository')
                        .appendNode('id', 'spring-releases').parent()
                        .appendNode('url', 'http://repo.spring.io/libs-release')
            }
        }
    }
}

task sourceJar(type: Jar) { 
    from sourceSets.main.allJava 
}

jar {
    baseName = 'my-api'
    version =  '0.0.1'
}

task('execJar', type:Jar, dependsOn: 'jar') {
    baseName = 'my-api'
    version =  '0.0.1'
    classifier = 'exec'
    from sourceSets.main.output
}

bootRepackage  {
    withJarTask = tasks['execJar']
}

// In this section you declare the dependencies for your production and test code
dependencies {
    // We use the latest groovy 2.x version for building this library
    compile 'org.codehaus.groovy:groovy-all:2.3.6'

    compile 'org.codehaus.groovy.modules.http-builder:http-builder:0.7.1'

    // tag::jetty[]
    compile("org.springframework.boot:spring-boot-starter-web") 
//  {
//  exclude module: "spring-boot-starter-tomcat"
//  }
//  compile("org.springframework.boot:spring-boot-starter-jetty")
//  end::jetty[]

    // tag::actuator[]
    compile("org.springframework.boot:spring-boot-starter-actuator")

    // We use the awesome Spock testing and specification framework
    testCompile 'org.spockframework:spock-core:0.7-groovy-2.0'
    testCompile 'junit:junit:4.11'
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('cglib:cglib:3.1')
}

// tag::wrapper[]
task wrapper(type: Wrapper) {
    gradleVersion = '2.1'
}

我的问题是，当我跑：

gradle publishToMavenLocal

我收到以下错误：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':publishMavenPublicationToMavenLocal'.
> Failed to publish publication 'maven' to repository 'MavenLocal'
   > Unable to initialize POM pom-default.xml: Cannot find parent: org.springframework.boot:spring-boot-starter-parent for project: com.proto:proto-api:jar:0.0.1 for project com.proto:proto-api:jar:0.0.1

我错过了什么？

提前感谢您的帮助。

Answer 1

好的，我已经解决了这个问题。我在公司防火墙后面，并在〜/ .gradle / gradle.properties文件中为gradle正确配置了代理。但是，我错过了在〜/ .m2 / settings.xml文件中为maven设置代理。

我配置了内部nexus存储库来处理此问题，但设置代理块也应该可以正常工作。 Click here for maven settings.xml documentation

Answer 2

与@aardee相同，我坐在我们的公司防火墙后面，但似乎我对maven local的代理设置（settings.xml）没有改变任何东西。幸运的是，我们拥有自己的maven存储库，可以代理，所以我只是更换了生成的pom中的存储库，并确保我们公司的maven存储库知道相关的spring存储库。

pom.withXml {
            asNode().appendNode('parent')
                    .appendNode('groupId', 'org.springframework.boot').parent()
                    .appendNode('artifactId', 'spring-boot-starter-parent').parent()
                    .appendNode('version', '1.1.8.RELEASE')

            asNode().appendNode('repositories').appendNode('repository')
                    .appendNode('id', 'spring-releases').parent()
                    .appendNode('url', 'http://my.mavenRepo.com/releases}

将http://my.mavenRepo.com/releases替换为您自己的maven存储库。

Spring-Boot项目的Gradle maven-publish抛出错误：无法找到parent：org.springframework.boot：spring-boot-starter-parent for project
