如何发布android-library项目的Jar包装？
我发现，classes.jar位于下面build/bundles/release/classes.jar，我想这是正确的Jar包（包含*.class文件）。

有什么正式的方法可以将库发布为JAR而不是AAR？

编辑
我使用Gradle发行了Maven构件，并且我想连同AAR包一起发行JAR。因此具有签名，md5，清单...
的JAR基于https://chris.banes.me/2013/08/27/pushing-aars-to-maven-central/

apply plugin: 'maven'
apply plugin: 'signing'

configurations {
    archives {
        extendsFrom configurations.default

if (isReleaseBuild()) {
    println 'RELEASE BUILD'
    sonatypeRepositoryUrl = "https://oss.sonatype.org/service/local/staging/deploy/maven2/"
} else {
    println 'DEBUG BUILD'
    sonatypeRepositoryUrl = "https://oss.sonatype.org/content/repositories/snapshots/"

if(!hasProperty('nexusPassword')) {
    ext.set('nexusPassword', System.console().readPassword("\n\$ Type in password for Sonatype nexus account " + nexusUsername + ": "))

    ext.set('signing.password', System.console().readPassword("\n\$ Type in GPG key password: "))
}

afterEvaluate { project ->
    uploadArchives {
        repositories {
            mavenDeployer {
                beforeDeployment { MavenDeployment deployment -> signing.signPom(deployment) }

                pom.artifactId = POM_ARTIFACT_ID

                repository(url: sonatypeRepositoryUrl) {

                pom.project {

                    packaging POM_PACKAGING
                    description POM_DESCRIPTION
                    url POM_URL

                    scm {

                    }
                }
            }
        }
    }

    signing {
        required { isReleaseBuild() && gradle.taskGraph.hasTask("uploadArchives") }
        sign configurations.archives
    }

    task androidJavadocs(type: Javadoc) {
        source = android.sourceSets.main.java.srcDirs
    }

    task androidJavadocsJar(type: Jar) {
        classifier = 'javadoc'
        from androidJavadocs.destinationDir
    }

    task androidSourcesJar(type: Jar) {
        classifier = 'sources'
        from android.sourceSets.main.java.srcDirs
    }

    artifacts {
        archives androidSourcesJar
        archives androidJavadocsJar
    }
}

使用

task androidJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
}

将仅打包Java文件，而不打包并针对android sdk链接

虽然我还没有尝试将带有部署的工件上传到Sonatype（甚至本地存储库），但是几周前，当我试图解决相同的问题时，我还是想出了这个方法。

android.libraryVariants.all { variant ->
  def name = variant.buildType.name
  if (name.equals(com.android.builder.core.BuilderConstants.DEBUG)) {
    return; // Skip debug builds.
  }
  def task = project.tasks.create "jar${name.capitalize()}", Jar
  task.dependsOn variant.javaCompile
  task.from variant.javaCompile.destinationDir
  artifacts.add('archives', task);
}

然后运行以下命令：
