JTB Examples
If you want to use JavaCC in combination with JTB, simply copy the following snippet into your POM and adjust the goal configuration where the default values do not fit your needs. A list of all configuration options can be seen on the jtb-javacc
goal page.
<project> ... <build> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>javacc-maven-plugin</artifactId> <version>3.1.1</version> <executions> <execution> <id>jtb-javacc</id> <goals> <goal>jtb-javacc</goal> </goals> <configuration> <!-- options for JTB and JavaCC go here --> </configuration> </execution> </executions> </plugin> ... </plugins> ... </build> ... </project>
If you know older versions of the plugin you might be glad to notice that you no longer need to setup two executions to have JTB and JavaCC run in a pipeline. The jtb-javacc
goal automatically runs both tools.
Once the plugin is properly configured, you can generate the parser along with the tree nodes files by executing the generate-sources
lifecycle phase:
mvn generate-sources
Alternatively, you can invoke the jtb-javacc
goal directly from the command line, i.e. without having any other goals run that might be bound to lifecycle phases of your build:
mvn javacc:jtb-javacc
Note: If you want to use the later call you need to put the <configuration>
element directly into the <plugin>
element. That is because the configuration inside the <execution>
element only applies if the goal is run as part of a lifecycle phase.
