[Maven]Add a Force Compile Property

[georgecao]

When I upgrade antlr to a new version, but keep the grammar files untouched, the grammar files will not be compiled but there is a warning message complaining the runtime version changed.

So I add a property forceCompile to skip the checksum and last modification date check and just re-compile the grammars.

I think you just need mvn clean. I am about to make a few tweaks to the plugin though. So I’ll take a look. But I doubt we can accept this. mvn clean compile

I add the plugin as follow:

             <plugin>
                    <groupId>org.antlr</groupId>
                    <artifactId>antlr4-maven-plugin</artifactId>
                    <version>4.13.1</version>
                </plugin>

and I tested mvn clean compile, but the grammar files were not re-compiled.
I read the code, beside the modification date of the grammar file, the plugin also check *.tokens files. I can force the re-compile by deleting the *.tokens files then run mvn clean compile.

Your configuration is wrong I think.

...
<executions>
 <execution>
  <goals>
   <goal>antlr4</goal>
  </goals>
 </execution>
</executions>
<configuration>
  <visitor>true</visitor>
  <sourceDirectory>src/main/antlr4</sourceDirectory>
</configuration>  

If your configuration is correct then check permissions and file times. There is no need for this flag.

I'm using a usual configuration https://github.com/khmarbaise/rpn-calculator/blob/master/pom.xml and it work without any issue... no supplemental source directory configuration needed... just follow the convention... https://github.com/khmarbaise/rpn-calculator/blob/master/rpn/pom.xml
