我如何可以释放 Android的库项目罐包装？ 我发现，classes.jar位于建立/包/发布/ classes.jar ，我想这是正确的Jar包（包含 *的.class 文件）。

How can I release Jar packaging of android-library project? I've found, classes.jar is located under build/bundles/release/classes.jar and I suppose this is correct Jar package (contains *.class files).

有一些官方的方式，来释放库JAR，而不是AAR？

Is there some official way, to release library as JAR instead of AAR ?

修改 我用摇篮释放Maven的文物，我想释放JAR随着AAR包。所以，JAR与签名，MD5，舱单，... 根据https://chris.banes.me/2013/08/27/pushing-aars-to-maven-central/

Edit I use Gradle to release Maven artifacts, and I'd like to release JAR along with AAR package. So JAR with signature, md5, manifest, ... based on https://chris.banes.me/2013/08/27/pushing-aars-to-maven-central/

    artifacts {

        archives androidJavadocsJar

}

使用

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

不编译和针对A​​ndroid SDK中联将仅打包java文件，

will package only java files, not compiled and linked against android sdk

推荐答案

虽然我没有试过上载文物有部署Sonatype的（甚至是当地的回购协议），这是我设法想出的试图解决同样的问题在几个星期前的时候。

While I haven't tried uploading the artifacts with a deployment to Sonatype (or even a local repo), here's what I managed to come up with a few weeks ago when trying to tackle the same problem.

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：

Then run the following:

./gradlew jarRelease
