It just a code from the sample MyModel.java class
```
package id.jeffersonsetiawan.aem.core.models;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.Default;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.settings.SlingSettingsService;
import javax.annotation.PostConstruct;
import javax.inject.Inject;
import javax.inject.Named;
/**

*/
@Model(adaptables=Resource.class)
public class MyModel {
@Inject
private SlingSettingsService settings;
@Inject @Named("sling:resourceType") @Default(values="No resourceType")
protected String resourceType;
@Inject @Named("title") @Default(values="No Title")
protected String javaTitle;
@Inject @Default(values="First Name")
protected String firstName;
@Inject @Named("lastName") @Default(values="No name defined")
protected String name;
private String message;
@PostConstruct
protected void init() {
message = "";
message += "\tThis is instance: " + settings.getSlingId() + "\n";
message += "\tResource type is: " + resourceType + "\n";
}
public String getMessage() {
return message;
}
public String getJavaTitle() {
return javaTitle;
}
public String message() {
return firstName + " " + name;
}
}```
I run mvn clean install -P autoInstallPackage, and everytime and change the java code, I use mvn clean install -P autoInstallBundle.
In author server, it works fine, when I replicate the package manager (apps and the content), I got the error.
