Thanks for the links to the documentation, I have been trying to get the
antlr-ant task to execute through gradle. I have the following build
configuration script so far:
apply plugin: 'java'
repositories {
mavenCentral()
}
configurations {
antAntlrConf
}
dependencies {
antAntlrConf 'ant:ant-antlr:1.6.+'
compile group: 'org.antlr', name: 'antlr-runtime', version: '3.+'
testCompile group: 'junit', name: 'junit', version: '4.+'
}
task generateGrammarSources (description: 'Invokes the antlr3-task from ant
to generate grammar sources') << {
generatedDir = new File(project.buildDir.toString() + '/generated-src/')
generatedDir.mkdirs()
ant {
taskdef(name: 'antlr',
classname: 'org.apache.tools.ant.taskdefs.optional.ANTLR',
classpath: configurations.antAntlrConf.asPath)
antlr(target: 'src/main/antlr3/Calculator.g', outputdirectory:
'build/generated-src/')
}
}
compileJava.dependsOn generateGrammarSources
This does not work yet, the build fails with the following error:
gradle clean generateGrammarSources
:clean
:generateGrammarSources
Trying to override old definition of datatype antlr
FAILURE: Build failed with an exception.
I don't understand what it means by "Trying to override old definition of
datatype antlr" I have been working on it for a while and was hoping I could
get a few points in the right direction.
