SparkSession中出现Exception in thread

1.使用SparkSession时，出现异常：Exception in thread "main" java.lang.AbstractMethodError
2.查看pom.xml文件，是否是因为spark-core和spark-sql的版本不匹配导致？

<dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-core_2.11</artifactId>
        <version>2.3.0</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.apache.spark/spark-sql -->
    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-sql_2.11</artifactId>
        <version>2.3.0</version>
    </dependency>
