Class not found (IWorkspaceRunnable) when deploying jodd to a servlet via gradle

Question

I'm trying to use Jetty to deploy a Jodd servlet. My build tool is Gradle. When I call gradle jettyRun, I get a ClassNotFound exception. I've tried adding various jars to the runtime, but I can't seem to find one that fixes this exception.

Here's my build.gradle:

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'war'
apply plugin: 'jetty'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.slf4j:slf4j-log4j12:1.7.5'
    compile 'org.jodd:jodd-madvoc:3.4.4'
    compile 'org.eclipse.jetty.orbit:javax.servlet:3.0.0.v201112011016'
    testCompile 'junit:junit:4.11'
    testCompile 'org.hamcrest:hamcrest-all:1.3'
}

and I get the following stack trace:

Answer 1

There was a problem how Madvoc was scanning the classpath in v3.4.4 :) As you can see from the classpath, error comes from AutomagicMadvocConfigurator - class that scans all jars for Madvoc actions. In short, scanning process was going 'too deep'. There are two ways how to solve this:

1. Limit the Madvoc scanning path, to skip the eclipse jars (not recommended).

2. Simply use latest 3.4.5 beta snapshot (soon to be released as final). We have fixed this issue there; you can check this without our example quickstart template. As you can see in README, you can run the Madvoc example with gradlew jettyRun and it should work.

I hope this works for you! If not, please let us know, and we will make it work for you.
