SparkSession实例化失败，请大侠帮忙看看可能是什么原因？

[果仁儿666]

在一个spark的工程中，之前一直用SparkContext执行程序没问题，现在因为想使用ML库，所以使用SparkSession，但是刚初始化就失败，应该是一个很简单的配置方面的问题，但因为没经验，找不出原因，搜了好久没看到完整的示范例子

val spark: SparkSession = SparkSession.builder
.appName("liqin Spark Application") // optional and will be autogenerated if not specified
.master("local

• "
• ) // avoid hardcoding the deployment environment
  .getOrCreate()
  
  build报错如下：
  
  
  pom.xml文件如下：
