/Users/liujingmao/IdeaProjects/sql/src/main/scala/com/mao/sparksql/SparkSqlContext.scala:28: error: Reference to class SQLContext in package sql should not have survived past type checking,
[INFO] it should have been processed and eliminated during expansion of an enclosing macro.
[INFO] val sqlContext = new SQLContext(sc)
[INFO] ^
错误二：
Failed to execute goal org.scala-tools:maven-scala-plugin:2.15.0:compile (default) on project sql: wrap: org.apache.commons.exec.ExecuteException: Process exited with an error: 1(Exit value: 1) -> [Help 1]

源代码：
package com.mao.sparksql

import org.apache.spark.SparkConf
import org.apache.spark.SparkContext

/**

*/

object SparkSqlContext {

def main(args: Array[String]): Unit = {
val path = args(0)

//Create sparkConf

val sparkConf = new SparkConf()

sparkConf.setAppName("SQLContextApp").setMaster("local[2]")

//创建SparkContext

val sc = new SparkContext(sparkConf)

//创建相应的Context

val sqlContext = new SQLContext(sc)
//处理相关的业务

val people = sqlContext.read.format("json").load(path)

people.printSchema()

people.show()

sc.stop()

}

}

先错误一解决下，把代码都删了

• 提问者 maomaoking #1

  把创建的Scala Object删除就能编译功能，并能得到 jar包，

• Michael_PK 回复 提问者 maomaoking #2

  那在重新创建一个object试试看

• 提问者 maomaoking 回复 Michael_PK #3

  这个问题解决了，pom文档里面有行没有注释掉，导致前后，报错！！！

先不要代码，先保证空的工程能正确编译先
