[GRADLE-2647] Annotations using the groovy plugin are unable to resolve classes passed to it. Created: 21/Jan/13  Updated: 10/Feb/17  Resolved: 10/Feb/17

 Description   

I have the following code example:

package com.example.helloworld;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;

@Produces(MediaType.APPLICATION_JSON)
public class HelloWorldService{  
}

This fails compilation using the groovy plugin with the following error message:

{pre}
Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: com.sun.ws.rs.ext.RuntimeDelegateImpl ... 17 more Caused by: java.lang.ClassNotFoundException: com.sun.ws.rs.ext.RuntimeDelegateImpl at org.gradle.api.internal.tasks.compile.TransformingClassLoader.findClass(TransformingClassLoader.java:47){pre}

However, it compiles fine once I remove the reference to mediaType and use a String.

@Produces('application/json')

The same code compiles fine in maven using the groovy eclipse plugin.

Which leads me to believe that something in the gradle classloaders break groovy compilation.

Our build.gradle file to reproduct this is as follows:

apply plugin: 'groovy'

// Set our project variables
project.ext {
    dropwizardVersion = '0.6.1'
}

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'com.yammer.dropwizard', name: 'dropwizard-core', version: dropwizardVersion
    groovy group: 'org.codehaus.groovy', name: 'groovy-all', version: '1.8.7'
}

Is the MediaType type an Enum?

Comment by tomas lin [ 21/Jan/13 ]

No, appears to be a class with static final strings - http://docs.oracle.com/javaee/6/api/javax/ws/rs/core/MediaType.html
