Apache Spark Maven POM错误

Question

我正在尝试使用Apache Spark并遇到一些我遇到的问题。我有一个来自Apache Spark Github的JavaSparkHiveExample.java示例以及我在IntelliJ IDEA中创建的Maven项目的pom.xml。

我可以运行其他Spark示例（使用另一个更简单的POM）但this one给出了以下错误：

• Scala已安装在Idea
中

我是Maven的新手，因此我会感谢一些我可以尝试解决这个问题的事情。

Answer 1

Issue is with the value of $project.version. It is referring to your project' version (2.3.0-snapshot). There isn't any maven dependency with this version in Maven central repository, hence you are facing this issue. Instead of using the project version, you can add a new property like this and refer it for all dependency version

FirebaseRecyclerOptions

and then use it in the dependency

<properties>
 <spark.version>1.6.2</spark.version>
</properties>

Make sure the version you are using is available in maven repository https://mvnrepository.com/
