Question

我有一个使用Mahout并使用Scala编写的spark程序。我尝试使用Maven构建它并拥有以下pom文件。

//When a user clicks "View all replies"...
$('.view1').click(function() {
    //Find the ID of the comment container he/she clicked inside
    var commentID = $(this).closest('.comment-container').attr('id');

    //Use that ID to make the selector more specific when targeting the reply elements
    $('.licom.' + commentID).toggle();
});

.....

当我尝试使用Maven构建它时，我收到以下错误消息：

我想知道maven为什么不能从mvnrepository下载mahout文件？

Answer 1

看看http://mvnrepository.com/artifact/org.apache.mahout/mahout-core我们可以看到最新版本的mahout-core是0.9。 mahout项目依赖项有所改变，您可能希望查看更新的mahout文档（https://mahout.apache.org/users/basics/quickstart.html）。
