Hello

I have had some trouble getting an Apex/Javascript project to load a Handlebars templating engine

this is what i have (i do have a templates directory, which contains a basic hbs template) :

$cat src/main/resources/server.js

console.log('startup');

var Router = require("vertx-apex-js/router");

var router = Router.router(vertx);

console.log('basics loaded');

var HandlebarsTemplateEngine = require("vertx-apex-js/handlebars_template_engine");

var TemplateHandler = require("vertx-apex-js/template_handler");

console.log('templating loaded');

var engine = HandlebarsTemplateEngine.create();

console.log('engine created');

var handler = TemplateHandler.create(engine);

console.log('templating created');

router.route().handler(handler);

console.log('handler set');

vertx.createHttpServer().requestHandler(router.accept).listen(8080);

console.log('server running');

But i get:

$ ./gradlew clean; ./gradlew shadowJar; java -jar build/libs/jstest-3.0.0-SNAPSHOT-fat.jar

This error is rather confusing, it seems to get to

router.route().handler(handler);

then have a problem on that line

my build.gradle:

buildscript {

repositories { jcenter() }

dependencies {

classpath 'com.github.jengelman.gradle.plugins:shadow:1.1.1'

}

apply plugin: 'java'

apply plugin: 'com.github.johnrengelman.shadow'

version = '3.0.0-SNAPSHOT'

if (!JavaVersion.current().java8Compatible) {

throw new IllegalStateException('''A Haiku:

| This needs Java 8,

| You are using something else,

| Refresh. Try again.'''.stripMargin())

}

repositories {

mavenCentral()

maven {

url = 'http://oss.sonatype.org/content/repositories/snapshots/'

}

dependencies {

compile 'io.vertx:vertx-core:3.0.0-SNAPSHOT'

compile 'io.vertx:vertx-lang-js:3.0.0-SNAPSHOT'

compile 'io.vertx:vertx-apex:3.0.0-SNAPSHOT'

compile 'io.vertx:vertx-auth-service:3.0.0-SNAPSHOT'

compile 'com.github.jknack:handlebars:2.0.0'

}

shadowJar {

classifier = 'fat'

manifest {

attributes 'Main-Class': 'io.vertx.core.Starter'

attributes 'Main-Verticle': 'js:server.js'

}

mergeServiceFiles {

include 'META-INF/services/io.vertx.core.spi.VerticleFactory'

}

task wrapper(type: Wrapper) {

gradleVersion = '2.0'

}

any help would be appreciated, thank you

which java version are you using? Julien mentioned something about a js bug in the versions below 8-40, maybe that is the same.

Come to think of it, it would be much easier to analyze the issue if you would put up a complete project e..g on github, the stack traces are hard to interpret as it is.

Thanks for getting back to me

here is my distilled project:

I more/less got my example code from here
