I have created a new component and when i try to use the sling model using data-sly-use
i get the below error , is there any reason for this error?

org.apache.sling.scripting.sightly.SightlyException: Compilation errors in org/apache/sling/scripting/sightly/apps/myproject/components/content/components/demo__component/demo__002d__component__002e__html.java:
Line 39, column 1932 : com.myproject.core.slingmodels.components.democomponent.DemoComponentModel cannot be resolved to a type

 This is my sling model

package com.myproject.core.slingmodels.components.democomponent;

import com.myproject.core.slingmodels.HeaderModel;
import lombok.Getter;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.ChildResource;


@Getter
@Model(adaptables = Resource.class,
        defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class DemoComponentModel {

    @ChildResource
    private HeaderModel Heading;
    
}

    Can you check if the package info file has been added -  this will scan the models 

    package-info.java

    @Version("1.0")
package com.your.sling.models.yourpackage;
import org.osgi.annotation.versioning.Version;

    Hi @zendark ,

    You may check status of bundle http://localhost:4502/system/console/bundles

     

    @Getter can be filed level or use @Data annotation for class level as mentioned below

    https://kiransg.com/tag/getter/

    You may check here how to use lambok https://experienceleaguecommunities.adobe.com/t5/experience-league-showcase-2022/using-project-lombok-in-aem-sling-models-write-less-code-for/cns-p/547343#:~:text=Once%20you%20add%20the%20%40Getter,in%20the%20outline%20in%20Eclipse.&text=Same%20way%20we%20can%20use,declare%20the%20setters%20at%20runtime

    If issue doesn't resolved you may have a look https://github.com/adobe/aem-project-archetype/issues/221 as your are using sub folder

    Thanks

      You need to check more entry in logs. It’s actually failing during compilation so it seems it has something to do with your code abd log will give you more insights on this.
      What about this class ? Have you defined it properly?

        Hi @zendark 

        Can you please check if you are adding the sling models package in pom as well

        <Sling-Model-Packages>com.myproject.core.slingmodels</Sling-Model-Packages>
