• It looks like you're using Maven -- when are you getting this error (please provide some more context)? – Zeleres Commented Aug 2, 2013 at 15:00
• I get this error when it is piling the gwt codes using the maven gwt plugin. – Kureem Rossaye Commented Aug 5, 2013 at 12:18

Well, I figured out what is the problem. In my pom.xml , I have this dependency

<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>4.7.0</version>

The problem with this is that, jasper reports has a dependency on jdtcore

        <dependency>
        <artifactId>jdtcore</artifactId>
        <groupId>eclipse</groupId>
        <version>3.1.0</version>
    </dependency>

jdtcore actually creates a conflict with the gwt piler. To solve this problem, I need to add an exclusion in the jasper dependency like this

        <dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>4.7.0</version>
        <exclusions>
            <exclusion>
                <artifactId>jdtcore</artifactId>
                <groupId>eclipse</groupId>
            </exclusion>
        </exclusions>
    </dependency>

Now if still need the jdtcore library in the web app (normally to dynamically pile jasper reports) we can add the dependency with scope runtime like this

    <dependency>
        <artifactId>jdtcore</artifactId>
        <groupId>eclipse</groupId>
        <version>3.1.0</version>
        <scope>runtime</scope>
    </dependency>

Last note, if anybody gets the problem, then should look if any dependency in pom.xml has got a dependency on jdtcore, exclude it and include it as runtime

Hope this helps

For gradle exclude transitive dependency as follows in build.gradle:

dependencies {
    pile('net.sf.jasperreports:jasperreports:3.7.4') {
        //Exclude as it caused problems with GWT:
        //http://stackoverflow./questions/17991063/java-lang-nosuchfielderror-reportunuseddeclaredthrownexceptionincludedocment
        exclude group: 'eclipse', module: 'jdtcore'  
    }  
}

Except after I made this change my jasper pilation fails. I am not sure yet how can I get Jasper pilation and GWT pilation to coexist in same project?
