Gradle and Android : pom configuration with multiple Maven artifacts publication

Question

Working on an Android library with Gradle (v 1.7) as the building tool, I\'ve used the maven plugin and configured the task uploadArchives to publish both release and debug vers

Answer 1

You need(ed) to set the filter name for the groupId and artifactId the same as you have for version

pom('debug').groupId = 'com.company'
pom('release').groupId = 'com.company'
pom('debug').artifactId = 'id'
pom('release').artifactId = 'id'
pom('debug').version = android.defaultConfig.versionName + "d"
pom('release').version = android.defaultConfig.versionName

Im surprised you get away with the version name suffix, as its not semver.

Answer 2

As a reference, this is how we upload multiple APKs. It may not be exactly what you needed since we are uploading multiple APKs after APK splits, while you were trying to upload multiple APKs from different build types (debug & release). But in theory, they should be the same.

//declare some Variables for later use
def projectName = "ProjectName"
def versionString = "1.0.0"
def baseVersionCode = 1

// Values based on https://developer.android.com/ndk/guides/abis.html#sa
ext.abiCodes = ['armeabi-v7a': 1,
                'arm64-v8a'  : 2,
                'x86'        : 3,
                'x86_64'     : 4]

// collect artifacts, important for the `uploadArchives` to work
artifacts {
  if (new File('app/build/outputs/apk').exists()) {
    new File('app/build/outputs/apk').eachFile() { file ->
      if (file.toString().contains("productionRelease")) {
        archives file: file
      }
    }
  }
}

uploadArchives {
  repositories {
    mavenDeployer {
      repository(url: "http://...")

      project.ext.abiCodes.values().each{ abiVersionCode ->
        def version = "${versionString}.${baseVersionCode + abiVersionCode}"
        addFilter(version) { artifact, file -> artifact.name.contains(version) }

        pom(version).artifactId = projectName.toLowerCase()
        pom(version).groupId = 'com.yourcompanyname'
        pom(version).version = version
      }
    }
  }
}

android {
  defaultPublishConfig "productionRelease"

  buildTypes {
      productionRelease {
          minifyEnabled false
          zipAlignEnabled true
          //...more Config like proguard or signing
      }
  }

  applicationVariants.all { variant ->
    variant.outputs.each { output ->
      def abiName = output.getFilter(com.android.build.OutputFile.ABI)
      def abiVersionCode = project.ext.abiCodes.get(abiName)    
      output.versionCodeOverride = variant.versionCode + abiVersionCode
      output.versionNameOverride = "$versionString (${output.versionCodeOverride})"
      def apkName = "$projectName-${variant.name}-v${versionString}.${output.versionCodeOverride}.apk"
      output.outputFile = new File(output.outputFile.parent, apkName)
    }
  }
