java.lang.NoSuchMethodError: org.reflections.util.ClasspathHelper.forPackag

See original GitHub issue

My code is like this public class MyApplication extends Application { public MyApplication() { BeanConfig beanConfig = new BeanConfig(); beanConfig.setVersion(“1.0.2”); beanConfig.setSchemes(new String[]{“http”}); beanConfig.setHost(“localhost:8080”); beanConfig.setBasePath(“/api”); beanConfig.setResourcePackage(“jerseyproject”); beanConfig.setScan(true);

}
@Override
public Set<Class<?>> getClasses() {
    final Set<Class<?>> classes = new HashSet<Class<?>>();
    // register root resource
    classes.add(MyResource.class);

    //you would need to add swagger-core's providers to the set up process.
    classes.add(io.swagger.jaxrs.listing.ApiListingResource.class);
    classes.add(io.swagger.jaxrs.listing.SwaggerSerializers.class);
    return classes;
}

}

but it throws error:

I solved this by using a newest version of google reflection jar

@denisgmarques Finally, I downgraded org.reflections to 0.9.10 (excluding com.google.guava and com.google.code.findbugs) and it worked for me.

I guess in you’r case, while downgrading swagger to 1.5.9 - under the hood version of org.reflections was downgraded and that fixed you’r problem.
