head -n 2 parser/target/generated-sources/antlr4/org/boazglean/dabar/grammer/DabarLexer.java 

// Generated from org/boazglean/dabar/grammer/DabarLexer.g4 by ANTLR 4.0
package org.boazglean.dabar.parser;

我是否遗漏了一些应该用来配置antlr4的命令？

创建语法文件夹结构/src/main/antlr4/org/nimy/antlr4/xml/xxxx.g4

在pom.xml中

<plugin>
    <groupId>org.antlr</groupId>
    <artifactId>antlr4-maven-plugin</artifactId>
    <version>4.1</version>
    <configuration>
        <listener>true</listener>
        <visitor>true</visitor>
        <arguments>
            <argument>-package</argument>
        </arguments>
    </configuration>
    <executions>
        <execution>
            <id>antlr-generate</id>
            <phase>generate-sources</phase>
            <goals>
                <goal>antlr4</goal>
            </goals>
        </execution>
    </executions>
</plugin>

GitHub上的antlt4 maven插件源代码。试着阅读它并获得配置项目的方法。antlr4源代码
