IDEA创建scala项目编辑pom.xml出现报错：Cannot resolve plugin org.scala-tools:maven-scala-plugin: unknown

首先检查文件中scala版本和spark版本是否与hadoop上一致

仍有报错，在配置文件中添加下载地址

<!-- https://mvnrepository.com/artifact/org.scala-tools/maven-scala-plugin -->
    <dependency>
      <groupId>org.scala-tools</groupId>
      <artifactId>maven-scala-plugin</artifactId>
      <version>2.11</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-eclipse-plugin -->
    <dependency>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-eclipse-plugin</artifactId>
      <version>2.5.1</version>
    </dependency>

问题解决
