How to solve error during include of component in Adobe Experience Manager?

Question

I am using Adobe Experience Manager with Eclipse, I've followed the instructions given in this tutorial https://docs.adobe.com/content/help/en/experience-manager-learn/getting-started-wknd-tutorial-develop/component-basics.html.

Everything was running fine. However, If I add a hello world component it gives me an error of:

Error during include of component '/apps/wknd/components/content/helloworld'

Error Message:

org.apache.sling.api.SlingException: Cannot get DefaultSlingScript: Compilation errors in org/apache/sling/scripting/sightly/apps/wknd/components/content/helloworld/helloworld_html.java: Line 52, column 2348 : com.adobe.aem.guides.wknd.core.models.HelloWorldModel cannot be resolved to a type

Any idea on how to solve this kind of issue or any other references about AEM Errors? Thank you!

Answer 1

Try to add this packages under build tag of core/pom.xml:

                    <configuration>
                        <bnd><![CDATA[ Import-Package: 
                          javax.annotation;version=0.0.0, \
                            com.day.cq.wcm.api;version=0.0.0, \
                            org.apache.sling.api.resource;version=0.0.0,\
                            org.apache.sling.api.servlets;version=0.0.0,\
                            *]]>
                        </bnd>
                    </configuration>

It worked for me!

Answer 2

This can occur because of two reason. 1) You didnt build the core module or your core bundle is not getting built properly. Use the command mvn clean install -PautoInstallBundle to build only the bundle.

2) Second reason might be your bundle is getting built and deployed on the server but the dependency is not getting resolved. Check in the system console if the bundle is active. If its not active then expand the bundle and check which dependency is missing. Once you find the missing dependency, then install the dependency in the osgi.

Answer 3

Try deleting your bundle in OSGi and install it again. Go to your core directory and run this command:

mvn -PautoInstallBundle clean install
