Generating ANTLR4 grammar files with package declaration in gradle -

i try use gradle antlr plugin, run several problems.

i have grammar file called wls.g4:

grammar wlsscript;  @header {    package hu.pmi.wls.antlr.ws; }   program   : 'statementlist'? eof   ;  // several more grammar , lexer rules 

(note: made statementlist keyword make correct grammer without including whole grammar. ;-))

this file located in /src/main/antlr (as default source folder of antlr production grammar files).

here snippet build.gradle:

project('common') {      apply plugin: 'antlr'      dependencies {        // dependencies         antlr "org.antlr:antlr4:4.5"     } }  

when use generategrammarsource gradle task (comming antlr plugin) generate source files generates files in build/generated-src/antlr/main folder default.

what goes wrong, doesn't create folders of java package (hu/pmi/wls/antlr/ws in our case) source incorrectly located in eclipse.

my primary question how force task generate source files in package-structured way? in other words, how can configure gradle task use package declaration grammar?

thanks!

i had exact same question , able change outputdirectory used antlrtask package name in there.

generategrammarsource {     outputdirectory = new file("${project.builddir}/generated-src/antlr/main/net/example".tostring()) } 

i found no easy way extract grammar package files had hardcode in task.
