记一次antlr错误：ANTLR Tool version 4.5.3 used for code generation does not match the current runtime vers

使用idea运行重构好的spark sql，在编译期出现如下错误：

ANTLR Tool version 4.5.3 used for code generation does not match the current runtime version 4.7.2ANTLR

原因：

<dependency>
            <groupId>org.antlr</groupId>
            <artifactId>antlr4-runtime</artifactId>
</dependency>

点击进入依赖，看当前antlr4的底层的依赖：

<plugin>
                <groupId>org.antlr</groupId>
                <artifactId>antlr4-maven-plugin</artifactId>
                <version>4.5.3</version> <!-- use older version to process XPathLexer.g4, avoiding cyclic build dependency -->
                <executions>
                    <execution>
                        <id>antlr</id>
                        <configuration>
                            <sourceDirectory>src</sourceDirectory>
                        </configuration>
                        <goals>
                            <goal>antlr4</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

这样就能对上错误问题了，因为使用4.7.2生成的代码。但是在编译期间是4.5.3；所以出错了

解决：

将4.5.3改成4.7即可
