Retrofit Integration with AEM Cloud

[samikshas963487]

Hi,

I am facing issue while using retrofit2 in my aem project.

I have added all the dependency and bundles as well.

Getting error in new OkHttpClient.Builder().

Error Message : noclassdeffounderror kotlin/jvm/internal/intrinsics

Hi @samikshas963487 
Please check, if you have retrofit2 osgi bundle installed and active, if not then try below:

• Convert a JAR file into an OSGi bundle 
• Including third party bundles in your AEM project

Hi @samikshas963487 , Please follow the steps suggested by @arunpatidar , Along with that you can also check on below points.

You’re encountering a NoClassDefFoundError related to Kotlin dependencies. This error typically occurs when the Kotlin standard library is not included in your project. 

• Add Kotlin Standard Library Dependency in pom.xml.

  <dependency>
      <groupId>org.jetbrains.kotlin</groupId>
      <artifactId>kotlin-stdlib</artifactId>
      <version>1.8.0</version>
  </dependency>

• Embed Kotlin Library in Your OSGi Bundle by configuring maven-bundle-plugin in pom.xml.

  <build>
      <plugins>
          <plugin>
              <groupId>org.apache.felix</groupId>
              <artifactId>maven-bundle-plugin</artifactId>
              <version>4.2.1</version>
              <extensions>true</extensions>
              <configuration>
                  <instructions>
                      <Embed-Dependency>kotlin-stdlib</Embed-Dependency>
                      <Embed-Transitive>true</Embed-Transitive>
                  </instructions>
              </configuration>
          </plugin>
      </plugins>
  </build>

• Ensure All Necessary Dependencies Are Included in pom.xml.

  <dependency>
      <groupId>com.squareup.retrofit2</groupId>
      <artifactId>retrofit</artifactId>
      <version>2.9.0</version>
  </dependency>
  <dependency>
      <groupId>com.squareup.retrofit2</groupId>
      <artifactId>converter-gson</artifactId>
      <version>2.9.0</version>
  </dependency>
  <dependency>
      <groupId>com.squareup.okhttp3</groupId>
      <artifactId>okhttp</artifactId>
      <version>4.9.0</version>
  </dependency>
  <dependency>
      <groupId>com.squareup.okhttp3</groupId>
      <artifactId>logging-interceptor</artifactId>
      <version>4.9.0</version>
  </dependency>

Hope this will help you !
