We should definitely go for the Maven plugin.
Everything else makes maintainability more difficult.
The Maven plugin doesn't look that complicated.
Change required in the parent `pom.xml`.
```
<project>
...
<properties>
...
<antlr4.maven.version>4.3</antrl4.maven.version>
...
</properties>
...
<build>
....
<pluginManagement>
<plugins>
<plugin>
<groupId>org.antlr</groupId>
<artifactId>antlr4-maven-plugin</artifactId>
<version>${antlr4.maven.version}</version>
</plugin>
....
```
Inside the zeppelin-interpreter `pom.xml`
```
<project>
...
<build>
....
<plugins>
<plugin>
<groupId>org.antlr</groupId>
<artifactId>antlr4-maven-plugin</artifactId>
</plugin>
...
</plugins>
</build>
...
</project>
```
Binds by default to the [lifecycle
phase](http://maven.apache.org/ref/current/maven-core/lifecycles.html):
generate-sources
All you need are grammar files inside `src/main/antlr4` and a "link"
implementation of zeppelin-interpreter to the generated source code.
