The output of processing multiple grammars from mutliple folders ends up in one
folder.
---------------------------------------------------------------------------------------
Key: MANTLRTHREE-9
URL: http://jira.codehaus.org/browse/MANTLRTHREE-9
Project: Maven 2.x Antlr3 Plugin
Issue Type: Bug
Affects Versions: 1.0
Environment: Maven version: 2.0.7
Java version: 1.6.0_03
OS name: "linux" version: "2.6.18-gentoo-r6" arch: "amd64"
Reporter: Benjamin Keil
Assignee: David Holroyd
Multiple grammars all end up in the same package (folder), even though the .g
files are in different packages.
For instance, in my project, I have these grammars:
{quote}
src/main/antlr/lumina/lucene/penelope/Penelope.g
src/main/antlr/lumina/lucene/reconstructedfield/ReconstructedField.g
src/main/antlr/lumina/lucene/lexisnexis/LexisNexisTree.g
{quote}
My configuration is simple:
{quote}
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>antlr3-maven-plugin</artifactId>
<version>1.0-beta-1</version>
<executions>
<execution>
<goals>
<goal>antlr</goal>
</goals>
</execution>
</executions>
</plugin>
{quote}
Each starts with appropriate headers. For example Penelope.g contains these
lines:
{quote}
@header {
package lumina.lucene.penelope;
}
@lexer::header {
package lumina.lucene.penelope;
}
{quote}
And ReconstructedField.g contains these lines:
{quote}
@header {
package lumina.lucene.reconstructedfield;
import java.util.List;
import java.util.ArrayList;
}
@lexer::header {
package lumina.lucene.reconstructedfield;
}
{quote}
With maven-anltr3-plugin-1.0-beta-1, I get the expected result, each parser in
its own package:
{quote}
target/generated-sources/antlr/lumina/lucene/lexisnexis/LexisNexisTreeParser.java
target/generated-sources/antlr/lumina/lucene/lexisnexis/LexisNexisTree.tokens
target/generated-sources/antlr/lumina/lucene/lexisnexis/LexisNexisTree__.g
target/generated-sources/antlr/lumina/lucene/lexisnexis/LexisNexisTreeLexer.java
target/generated-sources/antlr/lumina/lucene/reconstructedfield/ReconstructedFieldParser.java
target/generated-sources/antlr/lumina/lucene/reconstructedfield/ReconstructedField.tokens
target/generated-sources/antlr/lumina/lucene/reconstructedfield/ReconstructedField__.g
target/generated-sources/antlr/lumina/lucene/reconstructedfield/ReconstructedFieldLexer.java
target/generated-sources/antlr/lumina/lucene/penelope/PenelopeParser.java
target/generated-sources/antlr/lumina/lucene/penelope/Penelope.tokens
target/generated-sources/antlr/lumina/lucene/penelope/Penelope__.g
target/generated-sources/antlr/lumina/lucene/penelope/PenelopeLexer.java
{quote}
With maven-antlr3-plugin-1.0, all of the parsers end up in one package. Here
is the output of generate-sources:
{quote}

Perhaps it's important that Penelope is the last grammar processed, because all
of the files end up in the Penelope folder:
{quote}
target/generated-sources/antlr/lumina/lucene/penelope/ReconstructedFieldParser.java
target/generated-sources/antlr/lumina/lucene/penelope/ReconstructedField.tokens
target/generated-sources/antlr/lumina/lucene/penelope/ReconstructedField__.g

target/generated-sources/antlr/lumina/lucene/penelope/Penelope__.g

Even though the source points to the correct package:
{quote}
package lumina.lucene.lexisnexis;
import org.antlr.runtime.*;
import java.util.Stack;
import java.util.List;
import java.util.ArrayList;
import org.antlr.runtime.tree.*;
public class LexisNexisTreeParser extends Parser
