Error While trying to update core.wcm.components from 2.17.12 to 2.20.8

Hi @chandanaa9 

It seems like you are encountering a NoClassDefFoundError for the class com.adobe.cq.wcm.spi.AssetDelivery after updating the core.wcm.components from version 2.17.12 to 2.20.8. This issue might be caused by missing dependencies in your project's pom.xml.

To fix this issue, you need to add the missing dependency related to com.adobe.cq.wcm.spi.AssetDelivery. In this case, it is part of the core.wcm.components.servicesmodule.

Add the following dependency to your pom.xml:

<dependency>
<groupId>com.adobe.cq</groupId>
<artifactId>core.wcm.components.services</artifactId>
<version>2.20.8</version>
<scope>provided</scope>
</dependency>

If you still face issues, ensure that all your projects have the correct version of the dependencies. This includes the parent project, core project, and ui.apps project.

Here's a summary of the steps to update the dependencies:

1. Edit pom.xml and add the core.wcm.components.core and core.wcm.components.servicesdependencies in the <dependencies> section.

<dependencies>
...
<dependency>
<groupId>com.adobe.cq</groupId>
<artifactId>core.wcm.components.core</artifactId>
<version>2.20.8</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.adobe.cq</groupId>
<artifactId>core.wcm.components.services</artifactId>
<version>2.20.8</version>
<scope>provided</scope>
</dependency>
...
</dependencies>

1. Edit core/pom.xml and add the core.wcm.components.coredependency to the dependency list.
2. <dependencies>
   ...
   <dependency>
   <groupId>com.adobe.cq</groupId>
   <artifactId>core.wcm.components.core</artifactId>
   </dependency>
   ...
   </dependencies>
3. Edit ui.apps/pom.xml and add the core.wcm.components.allzip as a dependency in the dependency list.
4. <dependencies>
   ...
   <dependency>
   <groupId>com.adobe.cq</groupId>
   <artifactId>core.wcm.components.all</artifactId>
   <type>zip</type>
   <version>2.20.8</version>
   <scope>provided</scope>
   </dependency>
   ...
   </dependencies>

1. Edit ui.apps/pom.xml and include core.wcm.components.all zip as a sub-package.

<plugins>
...
<plugin>
<groupId>com.day.jcr.vault</groupId>
<artifactId>content-package-maven-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<group>your-group</group>
<filterSource>src/main/content/META-INF/vault/filter.xml</filterSource>
<properties>
<acHandling>merge_preserve</acHandling>
</properties>
<subPackages>
<subPackage>
<groupId>com.adobe.cq</groupId>
<artifactId>core.wcm.components.all</artifactId>
</subPackage>
</subPackages>
</configuration>
</plugin>
...
</plugins>

After updating the dependencies, try building the project again. If you still encounter issues, ensure that all the projects have the correct version of the dependencies.

Thankyou😊
