Dropwizard: Could not resolve type id 'http' into a subtype of [simple type, class io.dropwizard.jetty.ConnectorFactory]: known type ids = [ConnectorFactory]

[wejoy]

I am using the gradle to build the Dropwizard Application, it works fine until I run it.

My build.gradle is here:

apply plugin: 'java'
apply plugin: 'application'

project.ext {
    title = 'DWSample'
    baseName = 'DWSample'
    mainClass = 'com.hjess.dwsample.MainApp'
    version = '1.0.0'
}

task copyData(type:Copy) {
    from 'src/main/conf'
    into 'build/libs'
}

task release(type: Jar, dependsOn: 'copyData') {
    manifest {
        attributes 'Implementation-Title': project.ext.title,
                'Implementation-Version': project.ext.version,
                'Main-Class': project.ext.mainClass
    }
    baseName = project.ext.baseName + project.ext.version
    from {
        configurations.compile.collect {
            it.isDirectory() ? it : zipTree(it)
        }
    }
    with jar
}
repositories {
    mavenCentral()
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile group: 'io.dropwizard', name: 'dropwizard-core', version: '1.1.4'
}
tasks.withType(JavaCompile) {
    options.encoding = "UTF-8"
}

My yaml:

server:
  applicationConnectors:
    - type: http
      port: 8080

the release task can build a fatJar, then I run it, got an error:

E:\DWSample\server\build\libs>java -jar DWSample1.0.0.jar server main.yaml
main.yaml has an error:
  * Failed to parse configuration at: server.applicationConnectors.[0]; Could not resolve type id 'http' into a subtype of [simple type, class io.dropwizard.jetty.ConnectorFactory]: known type ids = [ConnectorFactory]
 at [Source: N/A; line: -1, column: -1] (through reference chain: com.hjess.dwsample.MainConf["server"]->io.dropwizard.server.DefaultServerFactory["applicationConnectors"]->java.util.ArrayList[0])

BTW, It works fine on Dropwizard 0.9.2 but got this error on v1.1.4

Your YAML file is hard to read. Is really everything written on one line? Could you please edit your question so that code/configuration is displayed as it is in your files?

@WeJoy You have to properly create an Uber-JAR and merge service files.
Also see http://www.dropwizard.io/1.1.4/docs/getting-started.html#building-fat-jars

There's the Gradle Shadow plugin which can be used for this.

Well, the problem has been solved by using https://github.com/johnrengelman/shadow, Thanks for the help!

Codes here

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.4'
    }
}

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

project.ext {
    baseName = 'DWSample'
    mainClass = 'com.hjess.dwsample.MainApp'
    version = '1.0.0'
    classifier = 'release'
}

shadowJar {
    mergeServiceFiles()
    mainClassName = project.ext.mainClass
    baseName = project.ext.baseName
    classifier = project.ext.classifier
    version =  project.ext.version
}

task release(type: Copy, dependsOn: 'shadowJar') {
    from 'src/main/conf'
    into 'build/libs'
}

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    def dwVersion = '1.1.4'
    compile group: 'io.dropwizard', name: 'dropwizard-core', version: dwVersion
}

tasks.withType(JavaCompile) {
    options.encoding = "UTF-8"
}

I'm using dropwizard 0.9.2 and facing this issue. I've been successfully running my application without using any shadow plugin. But suddenly it stopped working and I face the same issue while trying the run the jar file.

Running jar : java -jar ProjectName-1.0-SNAPSHOT.jar server configuration.yml

Here's my gradle file

group 'myGroup'
version '1.0-SNAPSHOT'

apply plugin: 'groovy'
apply plugin: 'java'

sourceCompatibility = 1.8

repositories {
    maven { url 'http://myArtifactory/jcenter' }
}

dependencies {
    compile 'org.codehaus.groovy:groovy-all:2.3.11'
    compile 'io.dropwizard:dropwizard-core:0.9.2'
    compile "org.glassfish.jersey.core:jersey-client:2.21"
    compile group: 'org.glassfish.jersey.media', name: 'jersey-media-json-jackson', version: '2.22.2'
    compile group: 'org.json', name: 'json', version: '20090211'
    compile group: 'com.googlecode.json-simple', name: 'json-simple', version: '1.1'
    compile group: 'org.mongodb', name: 'mongo-java-driver', version: '2.10.1'

    testCompile group: 'junit', name: 'junit', version: '4.12'
}

task fatJar(type: Jar) {

    manifest {
        attributes 'Implementation-Title': 'ProjectName',
                'Implementation-Version': version,
                'Main-Class': 'mypackage.DropWizardApplication'
    }
    baseName = project.name
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
}

0.9.2 is good without shadowJar, any version above is not.

Any ideas appreciated

Using 1.3.5 shadowjar/gradle and I'm getting (getting the same thing when I use gradle jar alone)
