AntlrTask don't working

plugins

(erlinve) #1

I want to create some different tasks with type AntlrTask
Default task (GenerateGrammarSource) - woking,
But extending tasks fall with error, or can’t get any source files.

Code:

apply plugin: 'java’
apply plugin: 'antlr’
sourceCompatibility = 1.7

dependencies {

antlr ':antlr:4.5.3-complete'

}

task genGramma(type: AntlrTask){

source = fileTree("$rootDir/proj/bla-bla/gramma").include('**/*.g4')
outputDirectory = file("$rootDir/proj/bla-bla/build/gen")

}

ALL PATH ARE GOOD

GRADLE 2.8

ERROR OUTPUT:

FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:sql:genGramma’.

java.lang.NullPointerException (no error message)

  • Try:
    Run with --info or --debug option to get more log output.

  • Exception is:
    org.gradle.api.tasks.TaskExecutionException: Execution failed for task ‘:sql:genGramma’.
