[AEM Package installation issue] : Newer package version com.myapp:myapp.ui.apps:x.x.x-SNAPSHOT was installed externally. Marking as ignored.

 

Few days back I was looking into a package installation issue in one of the environment.  Issue was related to deployment. Even after deployment was successful some packages were not getting installed automatically. I need to manually install those packages to have the update changes. 

Error log was saying something:

08.12.2022 08:42:54.382 *INFO* [OsgiInstallerImpl] com.adobe.granite.installer.factory.packages.impl.PackageTransformer Newer package version com.myapp:myapp.ui.content:2.10.0-SNAPSHOT was installed externally. Marking as ignored.




Reason:

In that particular instance, once some packages with version 3.0.0-SNAPSHOT was deployed and now we were trying to deploy package with version 2.10.0-SNAPSHOT, so AEM was not accepting those packages by saying that you already have higher version package installed. Means you already have updated code installed.

Solution:

In the above scenario, to make your latest code deployed automatically, you need to somehow increase the version of your current packages.

In my case, I updated the version of the package to 3.1.0-SNAPSHOT thru POM for all the modules. 

Note: I AM NOT ABLE TO REPRODUCE THE ISSUE IN OTHER AEM INSTALLATION.

Happy Debugging....!

Common cause for NullPionterException or Null value in Junit test case for sling model in aem

Image
  Below are the common cause for NullPointerException and Null value in Junit test for Sling model: Problem with the adaptables Let say your sling model is adaptables to sling Resource and in your test class you are trying to get the instance of your respective Object by adapting request of aemContext. In this case you will end up with NullPointerException.  For example: Sling Model : @Model ( adaptables = { Resource .class}, adapters = { SolutionHeroComponent .class}, resourceType = { SolutionHeroComponentImpl .RESOURCE_TYPE}, defaultInjectionStrategy = DefaultInjectionStrategy .OPTIONAL ) @Exporter ( name = "jackson" , selector = "solutionhero" , extensions = "json" ) public class SolutionHeroComponentImpl implements SolutionHeroComponent { protected static final String RESOURCE_TYPE = "myproject/components/solutionhero" ; @Inject @Named (SOLUTION_HERO_TITLE)

@Inject : A discouraged sling-model annotation

"I just copy and paste it from somewhere and since it was working so I keep it like this. 😎"           @ Model (adaptables = Resource . class )      public class ExampleModel { @ Inject private MyService myService ; @ Inject private String title ; // ... rest of the class } I got this reply from the developer while reviewing his code above so thought of writing one extension post of my previous blog  Common Myths Around Sling Model .  So lets dive into the working mechanism of @Inject annotation but before that I would like to explain the injector first.                                                                      An OOB injector      @ Component (property= Constants . SERVICE_RANKING + ":Integer=3000" ,                service={ Injector . class , InjectAnnotationProcessorFactory2 . class }) public class ChildResourceInjector extends AbstractInjector implements Injector ,      Inject

"java.lang.NoSuchFieldError: FACTORY" while running Junit test in AEM codebase

 I was implementing Unit testing for a already running AEM project. After adding all the dependencies and after creation of basic structure for Sling model test class my test gets executed as expected. @ ExtendWith ({ AemContextExtension . class , MockitoExtension . class }) class DummyComponentImplTest { @ BeforeEach void setUp () { } @ Test public void testGetHeading () { } } But soon as I add below line at line #25 in the above running test case private final AemContext aemContext = new AemContext (); and try to run the test in terminal getting below error in the terminal's maven console.
