Hi guys,
I am using the most recent maven archtype and therefore have the following folder structure:
Project Name
-Core
-it.launcher
-it.tests
-it.apps
-ui.content
I am importing an AWS dependency on my Master POM and Core POM
Master POM
<dependencyManagement>
<dependencies>
<!--AWS Dependencies -->
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>bom</artifactId>
<version>2.5.25</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-cloudfront</artifactId>
<version>1.11.534</version>
</dependency>
Core POM
<dependencies>
<!--AWS Dependency -->
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-cloudfront</artifactId>
</dependency>
The class using the AWS functionality is a custom workflow step that I have put inside the Core folder. However, when I deploy this to AEM I am getting "Cannot be resolved". I understand that just simply adding the dependency to the POM only helps compiling the code however the OSGI container is not able to see the dependency.
How can I fix this in my current project structure? I've read a few comments telling us to create some sort of eclipse bundle, but is there a more practical way to sort out this issue? We need this to be part of our continuous integration pipeline.
Many thanks in advance
Solved! Go to Solution.

Ok, I finally managed to get it to work! It was based on Macdonalds original advice.
For all reading this, ignore the <artifactId>aws-java-sdk-osgi</artifactId> bundle because it has a lot of dependency faults and version issues. You will end up driving yourself mad chasing dependencies. For anyone wanting to incorporate AWS related stuff DO NOT follow the AWS tutorial here Using the SDK with Apache Maven - AWS SDK for Java it will tell you to either install the "bom" package or the one that pulls all the dependencies <groupId>software.amazon.awssdk</groupId>. I just used the bit that interested me which was cloudfront, so I used the following dependency:
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-cloudfront</artifactId>
<version>1.11.534</version>
</dependency>
Then using that dependency only, I created a bundle in eclipse following the link Macdonald provided me Adobe Experience Manager Help | Submitting Adobe Experience Manager form data to Java Sling Servlets
The jar you need to build the bundle can be found in your .m2 folder.
It is very important that you remove all manifest related information from the bundle otherwise you will run into version problems.
Then deploy it to OSGI using the update button.
It should look something like this:
Bundle-Name: AWS-Cloudfront-AEM-Centrica-OSGI
Bundle-SymbolicName: AWS-Cloudfront-AEM-Centrica-OSGI
Bundle-Version: 1.0.0
Bundle-Vendor: Centrica
Automatic-Module-Name: AWS-AEM-Centrica-OSGI
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Export-Package: com.amazonaws, etc... etc... etc...
If you get the "cannot be resolved" issue regarding any of the things I mention in the printscreens above, DO NOT CHASE THEM you will end up going down a rabit hole.
Thanks to all that tried to help and especially, huge thanks Macdonald!!!

Include "bom" and "aws-java-sdk-cloudfront" in Embed-Dependency
example:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Bundle-Name>${project.name}</Bundle-Name>
<Embed-Dependency>bom,aws-java-sdk-cloudfront,*;scope=compile</Embed-Dependency>
<Import-Package>*</Import-Package>
</instructions>
</configuration>
</plugin>
If that doesn't work, please share your pom.xml's maven-bundle-plugin configuration

Try getting the JARs that expose these packages and wrap them into an OSGi bundle and deploy to AEM. That way - you know for sure these Java Packages are in the OSGi service container.

Thank you Macdonald! How do I do that with my Core bundle?

The nice thing about AEM is you can build an OSGi bundle that contains dependent JARS separate from your project. Any OSGi bundle that contains AWS JARs will resolve these Java packages for any OSGi bundle that requires them.
One way to build an OSGi bundle that contains other JARS is documented here - notice how we wrap the SIMPLE JSON JAR into a bundle.

Thanks Macdonald. I have done that and now I can see the dependency in the depfinder:
The problem is my project still can't find those dependencies:
My POM currently looks like this:
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-scr-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
</instructions>
</configuration>
</plugin>
</plugins>
</build>
If I add the following to the POM instructions in the POM
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-scr-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Embed-Dependency>aws-java-sdk-osgi,*;scope=compile</Embed-Dependency>
<Import-Package>com.amazonaws.*,*</Import-Package>
</instructions>
</configuration>
</plugin>
</plugins>
</build>
I get even more errors... Does this mean I need to wrap those extra dependencies to my project bundle I created separately? Kinda feels like I am going down a rabbit hole haha
Or are the instructions to the pom not the correct one? Help....

For com.fasterxml.* packages, install OSGIfied bundles from Maven Repository: Search/Browse/Explore
for org.springframework.*, aspectj.*, joda.* use Spring DM bundles and install in OSGI
for org.apache.http.*, update maven-bundle-plugin to import it dynamically from AEM-OOB -- use org.apache.httpcomponents.httpcore
for netty, use OSGIfied bundle
for amazon.*, either use OSGIfied bundles or package them into your code bundle using Embed-Dependency as mentioned above

What do you mean by OSGified bundles?

I meant OSGI bundles and not that jar files (you'd find both versions on web in mvnrepository and other sites)

Mate the bundles are already there... I don't have to install them again. I can find them through the depfinder
Problem is they cannot be resolved... Same happens to the AWS packages. I followed Macdonalds advice and created a bundle that exports them, but for some reason they are not picked up.

If a bundle is already available/active in OSGI say com.fasterxml.jackson.annotation then add its symbolic name to maven-bundle-plugin in your pom.xml and test it
<Require-Bundle>com.fasterxml.jackson.annotation</Require-Bundle>
Alternatively, you could also package the jar/bundle within your code-bundle so that it resolves using internally available classes as Scott mentioned -- use <Import-Package>.... </Import-Package> for same

Hi Filip,
What's the problem with using [0], this one has been adapted for OSGi, so you don't have to mess with the dependencies yourself:
[0] Maven Repository: com.amazonaws » aws-java-sdk-osgi

Peter

Thanks Peter!
That's the dependency I am using as well in the Core POM.
I tried it before but when I install that dependency on OSGI though I get these errors:

Hi Filip,
For the dependencies that can't be resolved by your Apache Felix OSGi context, you would either set them as ignored in your OSGi context or help AWS bundle to resolve these by having them present in your OSGi system.

Peter

Hi Mr Scott, I am trying to download a file from AWS S3 bucket via AEM backend code in a seperate workflow process step.
I am unable to get the bundle resolved when I use various AWS API dependencies.
I tried using the dependency jar as below:
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-osgi</artifactId>
<scope>provided</scope>
</dependency>
Error we are getting in ISGI bundle here is :
Imported Packages | com.fasterxml.jackson.annotation,version=[2.12,3) -- Cannot be resolved |
Can you please help to resolve it with proper AWS API dependecy to use and how to resolve the bundle in felix console by providing the corect link address.
Thanks
