Failed to instantiate MessageBodyReader error
First of all, I have to say that I am new to Maven, even thought I didn't think Maven had anything to do with this error. I am using Eclipse 4.2.1 with m2e
I have this code I got from ckan4j developer
Client c = ClientBuilder.newBuilder().register(MultiPartFeature.class).build();
WebTarget wt = c.target("192.168.1.2/action").path("resource_update");
Builder b = wt.request();
b.header("authorization", "fa0499d1-ffda-4590-82b3-4afdb9c91576");
FileDataBodyPart filePart = new FileDataBodyPart("upload", new File("/home/ilias/Downloads/OdtUtils.java"));
FormDataMultiPart multipart = (FormDataMultiPart) new FormDataMultiPart().field("id","test2").bodyPart(filePart);
String response_string = b.post(Entity.entity(multipart, multipart.getMediaType())).readEntity(String.class);
System.out.println(response_string);
this is my pom.xml file

I'm not 100% sure about the dependencies, but I just looked for the error I was getting during compilation and added the results here until I got any errors. Now when I build maven (using generate-sources
) I get this
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J:

who even thought he was complaining about the registrar, I don't really want to decide now. other than that it seems to be okay.
When trying to execute java file I get this

I used the xml tag just to make the xml more readable
source to share
I had the same problem caused by a combination of RestEasy and Jersey (org.glassfish.jersey.media):
ResteasyProviderFactory factory = ResteasyProviderFactory.getInstance();
ResteasyProviderFactory.pushContext(javax.ws.rs.ext.Providers.class, factory);
Another hint is to use the jersey-media-multipart dependency rather than jersey-multipart
