Question

我是Android开发的新手，我正在尝试通过BinTray将一个简单的测试库（我正在为学习目的构建）部署到JCenter和MavenCentral。我已通过BinTray成功部署到JCenter，但未能成功继续部署到MavenCentral。

以下是我收到的MavenCentral REST API错误：

HTTP/1.1 400 Bad Request [messages:[Invalid POM: /pro/johnfoley/androidTesting/testlibrary/1.0.5/testlibrary-1.0.5.pom: Project name missing, Project description missing, Project URL missing, License information missing, SCM URL missing, Developer information missing, Dropping existing partial staging repository.], status:Validation Failed]
11:45:57 AM: External task execution finished 'bintrayUpload'.

这是我的build.gradle：

apply plugin: 'com.android.library'
apply plugin: 'com.jfrog.bintray'
apply plugin: 'com.github.dcendents.android-maven'

description = 'A test library'
group = 'pro.johnfoley.androidTesting'
version = '1.0.5'

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    apply plugin: 'maven'
    apply plugin: 'maven-publish'
}

    }
    buildTypes {
        release {
            minifyEnabled false

        }
    }

def bintrayUser = 'BT_USER'
def bintrayApiKey = 'BT_KEY'

def mavenCentralToken = 'MC_TOKEN'
def mavenCentralPassword = 'MC_PW'

// BinTray config
bintray
{
    user = bintrayUser
    key = bintrayApiKey

    pkg
    {
        repo = 'maven'
        name = 'pro.johnfoley.androidTesting.testlibrary'
        desc = ''
        licenses = ['Apache-2.0']
        vcsUrl = 'https://github.com/johnlfoleyiii/androidTesting.git'
        issueTrackerUrl = 'https://github.com/johnlfoleyiii/androidTesting/issues'
        websiteUrl = 'https://github.com/johnlfoleyiii/androidTesting'
        labels = []
        publicDownloadNumbers = true

        version {
            name = '1.0.5-testlibrary'
            desc = 'My test library'
            released  = new Date()
            vcsTag = 'v1.0'
            gpg {
                sign = true
                passphrase = bintrayGPGPassword
            }
            mavenCentralSync {
                sync = true //Optional (true by default). Determines whether to sync the version to Maven Central.
                user = mavenCentralToken
                password = mavenCentralPassword
                close = '1' //Optional property. By default the staging repository is closed and artifacts are released to Maven Central. You can optionally turn this behaviour off (by puting 0 as value) and release the version manually.
            }
        }
    }

    configurations = ['archives']
}

这是从build.gradle生成的POM：

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <dependencies>
    <dependency>
      <groupId>com.android.support</groupId>

      <version>23.4.0</version>
      <scope>compile</scope>
    </dependency>
  </dependencies>
</project>

如何配置build.gradle以通过BinTray成功部署到MavenCentral？
