New ANTLRv4 Maven Plugin

[Hans Uhlig]

I got a bit frustrated trying to clean up and convert the existing maven plugin so I went back and started from scratch. 

https://github.com/huhlig/antlr4-maven-plugin

Available here, it currently exposes all of the options inside maven and I fixed the null directory problem. I am fully open to feedback and happy to donate the code and rights over to ANTLR

[Terence Parr]

Sam, is Hans' plugin better? can we bring that in or should we tweak the existing?

I should get to this one in detail this weekend.

I am working to see if I can add a second task for Testrig and some level of automated testing.

[Sam Harwell]

Hi Hans,

 

I just checked in a major update to the Maven plugin. Its usage is substantially simplified, and offers the following advantages over other implementations:

 

·         Several unused and/or non-functional options were removed.

·         Several configuration options may be overridden by setting properties like antlr4.listener, antlr4.visitor, etc. in a pom.xml or on the Maven command line.

·         An “arguments” property is available for appending arbitrary arguments to the tool command line. This allowed me to remove some rarely used parameters and makes sure the Maven plugin still works if/when the tool is modified in the future.

·         The -package option is automatically derived from grammar paths, and calls to the tool are batched to ensure it’s always correct. You no longer have to specify a package in the grammar (in fact, doing so in a @header{} block would break the build).

Has this been pushed out to sonatype?

[Hans Uhlig]

Also are you planning a new version of gunit for antlr4 or another way of unit testing grammars?

[Terence Parr]

Hi. we've abandoned gunit since pure java code looks almost as good as gunit tests.

I just updated the 4.0-SNAPSHOT artifact.

Ok, I cleared and got the new maven plugin. It doesn't seem to run. Perhaps I am doing something wrong. 

what is the goal to call it explicitly?

[Sam Harwell]

Hi Hans,

 

For a minimal setup you can start with the following. Grammars will be compiled as part of the normal build process.

 

<plugin>

  <groupId>org.antlr</groupId>

  <artifactId>antlr4-maven-plugin</artifactId>

  <version>4.0-SNAPSHOT</version>

  <executions>

    <execution>

      <goals>

        <goal>antlr</goal>

      </goals>

      <configuration>

        <!-- Include this line if you place your .g4 files in the same root folder as your Java source files. -->

        <!--<sourceDirectory>${basedir}/src/main/java</sourceDirectory>-->

      </configuration>

    </execution>

  </executions>

</plugin>

back to the same problem as before. The plugin is always resolving the relative directory to null.

Hi Hans,

 

The error is happening because your grammar is located in the root of the project and not within a particular package.

 

I opened the following issue related to handling of files in the default package:

https://github.com/antlr/antlr4/issues/94

This issue is now fixed and I pushed the update to Sonatype.

Can you upload the antlr-runtime:jar:3.5.1-snapshot as it appears to be a dependency of the antlr4-maven-plugin

[Sam Harwell]

I deployed a new 4.0-SNAPSHOT build of ANTLR 4 (including antlr4-maven-plugin), which now depends on the 3.5-rc-1 release of antlr-runtime in Maven Central.

 

P.S. 3.5.1 was an incorrect version number. The next release of ANTLR 3 will be 3.5. I removed all of the 3.5.1-SNAPSHOT builds from Sonatype for this reason.
