Question
Working REST + file upload, using resteasy 2.2.1.GA and Eclipse 3.6. And the reseteasy multipart dependency is declared in maven pom.xml file.
In compile mode, class “MultipartInput” is able to compile, but Eclipse prompts following error message during deployment or debugging mode?
java.lang.NoClassDefFoundError: org/jboss/resteasy/plugins/providers/multipart/MultipartInput
at java.lang.Class.getDeclaredMethods0(Native Method)

Solution
In Maven + Eclipse development, double confirm that the “resteasy-multipart-provider” is declared in Maven pom.xml file properly.
File : pom.xml
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-multipart-provider</artifactId>
<version>2.2.1.GA</version>
</dependency>
Issue below Maven command to make sure all dependencies are deployed during Eclipse debugging environment.
mvn eclipse:eclipse -Dwtpversion=2.0

Do you know what the solution might be for this when you are working in Android Studio with Gradle instead of Maven and Eclipse?
