CodeGen - Unable to generate code for interfaces
James Bench
Hello,
I've written a custom authentication Handler/Provider allowing VertX web to use an internal system to provide authentication - it works great :-)
I've been trying to use the VertX-RX library to see if we prefer the programming style and I therefore want to generate an RX version of my library using CodeGen.
So far I have done the following:
· Added io.vertx:vertx-codegen:3.2.1 as a dependency.
· Added @VertxGen() annotations too my AuthHandler and AuthProvider interfaces.
· Added a package-info.java to the project:
@ModuleGen(name
= "vertx-customauth", groupPackage="uk.co.spgroup")
package uk.co.spgroup.vertxcustomauth;
· Added the annotation processor to my Gradle build file:
apply
plugin: 'java'
apply plugin: 'maven'
apply plugin: 'idea'
group 'uk.co.spgroup'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
ext {
generated = file("$projectDir/src/main/generated")
}
configurations {
annotationProcessor
}
sourceSets {
main {
java {
srcDirs generated
}
}
}
dependencies {
compile 'io.vertx:vertx-auth-common:3.2.1'
compile 'io.vertx:vertx-web:3.2.1'
compile 'io.vertx:vertx-codegen:3.2.1'
testCompile group: 'junit', name: 'junit', version: '4.11'
annotationProcessor 'io.vertx:vertx-codegen:3.2.1'
}
task cleanGenerated(type: Delete) {
delete generated
}
compileJava {
dependsOn cleanGenerated
doFirst {
mkdir generated
}
options.compilerArgs += [
"-s", generated,
"-AoutputDirectory=$projectDir/src/main",
"-processor",
"io.vertx.codegen.CodeGenProcessor"
]
classpath += configurations.annotationProcessor
}
· And run a build:
14:42:54:

:clean

BUILD SUCCESSFUL
Total time: 0.55 secs

But the generated folder remains empty?
I assume I've missed a step or annotation somewhere but I can't figure it out -
has anyone any experience with this and are you able to point me in the right
direction?
Cheers,
JB
