1、Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.4.6:compile (scala-compile-first) on project test: wrap: org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1)

错误原因：①需要添加spark-sql依赖

        <dependency>
            <groupId>org.apache.spark</groupId>
            <artifactId>spark-sql_${scala.version}</artifactId>
            <version>${spark.version}</version>
            <scope>provided</scope>
        </dependency>
--------------
        <dependency>
            <groupId>org.apache.spark</groupId>
            <artifactId>spark-sql_2.11</artifactId>
            <version>2.10</version>
            <scope>provided</scope>
        </dependency>

②打包路径下不能存在中文和空格

使用<scope>provided</scope>将依赖不进行打包，使用平台提供的依赖

同时通过参数：

--conf spark.executor.userClassPathFirst=true   --conf spark.driver.userClassPathFirst=true

指定driver + executor均使用用户jar
