Fixes for the Gradebook AssetPublisher part

AssignmentRenderingFactory

@Reference(target = "(osgi.web.symbolicname=com.liferay.training.space.gradebook)")
private ServletContext _servletContext;

@Override
public PortletURL getURLAdd(
	LiferayPortletRequest liferayPortletRequest,
	LiferayPortletResponse liferayPortletResponse, long classTypeId) {
	PortletURL portletURL = null;

	portletURL = _portal.getControlPanelPortletURL(
				liferayPortletRequest, getGroup(liferayPortletRequest),
				GradebookPortletKeys.PORTLET_NAME, 0, 0, PortletRequest.RENDER_PHASE);
	
	portletURL.setParameter("mvcRenderCommandName", "/gradebook/assignment/edit");
	portletURL.setParameter("showback", Boolean.FALSE.toString());
	
	return portletURL;
}

From gradebook-web/build.gradle change version like below

compileOnly group: "com.liferay.portal", name: "com.liferay.portal.kernel", version: "2.6.0"

AssignmentAssetRenderer

Modify the getURLEdit

@Override
public PortletURL getURLEdit(
		LiferayPortletRequest liferayPortletRequest,
		LiferayPortletResponse liferayPortletResponse)
	throws Exception {

	Group group = (Group)liferayPortletRequest.getAttribute(
			WebKeys.ASSET_RENDERER_FACTORY_GROUP);

	PortletURL portletURL = PortalUtil.getControlPanelPortletURL(
		liferayPortletRequest, group,
		GradebookPortletKeys.PORTLET_NAME, 0, 0, PortletRequest.RENDER_PHASE);

	portletURL.setParameter("mvcRenderCommandName", "/gradebook/assignment/edit");
	portletURL.setParameter(
		"assignmentId", String.valueOf(_assignment.getAssignmentId()));
	portletURL.setParameter("showback", Boolean.FALSE.toString());

	return portletURL;
}

GradebookPortlet

Make also portlet non instanceable by modifying GradebookPortlet class.

@Component(
	immediate = true,
	property = {
		"com.liferay.portlet.add-default-resource=true",
		"com.liferay.portlet.display-category=category.sample",
		"com.liferay.portlet.instanceable=false",
		"javax.portlet.display-name=gradebook-web Portlet",
		"javax.portlet.init-param.template-path=/",
		"javax.portlet.init-param.view-template=/view.jsp",
		"javax.portlet.name=" + GradebookPortletKeys.PORTLET_NAME,
		"javax.portlet.resource-bundle=content.Language",
		"javax.portlet.security-role-ref=power-user,user",
		"javax.portlet.init-param.add-process-action-success-action=false"
	    
	},
	service = Portlet.class
)
