Could not resolve type id 'http'

I've just created a new 0.7 project (working on upgrading our other services, but wanted to test flight the new version), and I'm getting a really strange error:

* Failed to parse configuration at: server.connector; Could not resolve type id 'http' into a subtype of [simple type, class io.dropwizard.jetty.ConnectorFactory]
at [Source: N/A; line: -1, column: -1] (through reference chain: com.oe.dbsvc.DbSvcConfiguration["server"]->io.dropwizard.server.SimpleServerFactory["connector"])

The content of our config yaml looks like this:

server:
type: simple
connector:
type: http
port: 8001
database:
driverClass: org.postgresql.Driver
user: blah
password: blah
url: jdbc:postgresql://localhost/blah
properties:
charSet: UTF-8
validationQuery: "/* MyService Health Check */ SELECT 1"
minSize: 8
maxSize: 32
# whether or not idle connections should be validated
checkConnectionWhileIdle: false
# how long a connection must be held before it can be validated
checkConnectionHealthWhenIdleFor: 10s
# the maximum lifetime of an idle connection
closeConnectionIfIdleFor: 1 minute

I've also tried it with the more specific "applicationConnectors" approach (which we'll need for our actual applications):

server:
applicationConnectors:
- type: http
port: 8001
adminConnectors:
- type: http
port: 8002

Same error message. Do I need to register something else somewhere to get this working?

Thanks to anyone who can give us a pointer!

Chris,

I was just able to run using the configuration you provided without any issues against 0.7.0-rc1. Can you provide any other information?

The oddity appears to be in the build process, which I should have mentioned in my previous post - we're using Gradle and the Gradle shadow plugin to build the fat jar (which is working for us on 0.6.2 of Dropwizard). There's literally just an Application class and a Configuration class in the project, but for whatever reason the fat jar doesn't work. However, it DOES run fine under IntelliJ, so signs point to Gradle or Gradle shadow. I'm debugging it now and will report what I find out.

What version of Gradle? Also, are you using Groovy and Java 7? All these versions interact for 0.6.2 and I suspect will just as much for 0.7.

We're using Gradle 1.10, Java 7u45 (on Mac OSX), but no Groovy in the app. Below is the list of compilation dependencies according to Gradle:

With some help from Matt Veitas, I was able to get it working. It was indeed the Gradle Shadow process, our build script was missing the ServiceFileTransformer - not sure why we didn't need this before with 0.6.2, but it's definitely needed now. After that went in there, everything ran as expected.

Thanks for the help, guys!

That sounds very familiar. Can you elaborate on the solution? I'm having similar errors parsing the .yml file as well.

I'm using Maven to build a fat jar. ( but I'm having issues with the parsing of the default .yml file, where it appears to look for http )

Can you include the snippet from your Maven that builds the fat jar?

This is the snippet I have included in my Gradle file. This is based upon the Gradle Shadow plugin: https://github.com/johnrengelman/shadow

import com.github.jengelman.gradle.plugins.shadow.transformers.AppendingTransformer

import com.github.jengelman.gradle.plugins.shadow.transformers.ManifestResourceTransformer

import com.github.jengelman.gradle.plugins.shadow.transformers.ServiceFileTransformer

shadow {

baseName 'myapp-bundle'

artifactAttached false

destinationDir "${project.buildDir}/distributions"

transformer(ServiceFileTransformer)

transformer(ManifestResourceTransformer) {

attributes 'Main-Class': 'com.mycompany.MyAppServer'

attributes 'Test-Entry': 'PASSED'

}

transformer(AppendingTransformer) {

resource = 'META-INF/spring.handlers'

}

transformer(AppendingTransformer) {

resource = 'META-INF/spring.schemas'

}

exclude 'META-INF/*.DSA'

exclude 'META-INF/*.RSA'

}

Aside from the $ signs (which I assume are EOL markers?) that looks right.

The reason the ServiceResourceTransformer (or equivalent) wasn't necessary before was that 0.6 didn't use them. 0.7 uses services for discovering polymorphic configuration blocks. This allows you to add your own sub-types that the configuration parser will detect, without having to change any of configuration classes.
