hi folks
I am trying to embed one of our java client libraries into AEM.
I followed:
https://www.linkedin.com/pulse/how-add-third-party-bundle-you-aem-package-veena-vikraman/
in ui.apps, I created an "install" directory with the client lib ( which was converted into a OSGi bundle)
In content-package-maven-plugin, I added "embeddeds" and "embedded" and added the group, artifact id and the target directory.
in aem.core,for "maven-bundle-plugin" I added the artifact id to the Embed-Dependency list.
I added Dependencys to aem.core and the parent pom.xmls... with scope of "provided".
However I got these errors. Am I missing some step?
thanks.
Fiona

Hi fionas,
I have similar restriction in my project with a third-party jar which is not available to download via maven dependency.
Here is what I did and it's working perfectly with cloud manager deployments.
- Using maven local repository concept and create a local repo within the project structure and commit it as part of your codebase.
- Refer the local repo within the main pom.xml under the <repositories> section.
- Add the third party jar as any other maven dependency using the <dependency> tag.
- Export the classes of your jar file using <plugin> --> maven-bundle-plugin --> <_exportcontents> tag.
Checkout the screenshots to get a idea.
Thanks,
Sudheer.
Hello @fionas76543059
jar to bundle conversion:
- When we convert a jar to bundle, we need to make sure that the Manifest file has proper exports.
- The easiest way to convert a jar to bundle is to use bnd tool. It can be downloaded from http://www.java2s.com/Code/Jar/b/Downloadbndjar.htm
- Once downloaded, execute following command
Command:
java -jar bnd.jar wrap <your_jar>.jar
- A file will be generated, change its extension to .jar
Deploying bundle to AEM: Multiple approaches
Key is to get your jar->bundle right first
Hello @fionas76543059 ,
The process you followed should work for an OSGI-ready jar. But some jar files are not installed in OSGI by this process. You can follow this documentation to install your jar file into OSGI. https://myaemlearnings.blogspot.com/2021/08/embedding-third-party-dependencyosgi.html
For this, you need to add an extra module, I Hope this will help you.
Thanks for all the suggestions.
Our API code is proprietary, not in a public repo, and our company repository is not contactable for the Adobe pipelines.
I am hoping that when I install the OSGi bundle that I have made from my code, that the Adobe pipeline will put the code into its /root/.m2/repository to be available as a dependency to compile the code in "core"
I wonder does the order of the modules matter?
I don't think so. I tried both ways to embed that additional module before and after the core module. Yes, both times it runs fine.
oK, thanks, Have you ever tried it with a bit of proprietary code that isn't available in a public maven repo ?
Yes, On that case you can put your project as private repository manage by s3.
Check this documentation: https://github.com/seahen/maven-s3-wagon
Step 1: Need to deploy your private codebase to s3.
<extensions>
<extension>
<groupId>com.github.seahen</groupId>
<artifactId>maven-s3-wagon</artifactId>
<version>1.3.3</version>
</extension>
</extensions>
<distributionManagement>
<repository>
<id>s3-snapshots</id>
<url>s3://your-private-repo/releases</url>
</repository>
<snapshotRepository>
<id>s3-snapshots</id>
<url>s3://your-private-repo/snapshots</url>
</snapshotRepository>
</distributionManagement>
Setup the S3 access key in .m2/settings.xml and put the credential in PC environment variable.
Step 2:: Deploy the project in s3 using mvn clean deploy
Step 3: Import your private project into your client project as a maven dependency.
Note: These all are the overall idea. But it's very popular for private repository management. You can do some research and POC to execute this.
Another way can be to use NEXUS Repository Management. But this will lead you to some additional server manage costs.
Thanks !
I can't have a public repo in S3 or nexus.
I was hoping your approach 2 in your link above meant I didn' t need a public repo.
Hello @fionas76543059
If you can create the jar as a bundle in Project, CM/maven will be able to compile and put it in .m2 repository.
Yes, the order matters. Please assure that this converted bundle is added as a dependency in the other core bundle used in the project. That way, it will compile first, install in .m2 first and will be ready to be used by the other bundle.
For the other bundle to be able to use it, make sure that the Export-Packages etc of converted target are configured properly.
In case, you are doubtful about how to configure MANIFEST.MF, please take help of the bnd tool. You can create a bundle, extract the MANIFEST.MF and use in your converted module
No, maybe you didn't get my point. Using S3 wagon or Nexus you can create your own repository management tool. That will feel like Maven Public Repository. But without a proper credential, no one can access your repository.
These actually make your dependency as a private dependency.
In your last question, I don't think so, You won't have that access to put jar in cloud m2. Most importantly that's not recommended at all and its a very risky job.
The method you are following should work. Did you add the dependency in apps pom.xml where you are actually trying to embed it?

Thank you!
That looks interesting. I will give it a try
hi, I tried your idea but it didn't work for me : -(
I created a repository directory at the top level and put the jar file in there.
I ran this command.
mvn org.apache.maven.plugins:maven-install-plugin:3.1.1:install-file -Dfile="./repository/./xx-api-client-jdk8-1.21.0-SNAPSHOT.jar" -DgroupId=com.xxxx -DartifactId=xxx-api-client-jdk8 -Dversion=1.21.0-SNAPSHOT -Dpackaging=jar -DlocalRepositoryPath=repository -DgeneratePom=true
I then removed the jar and pushed the results of the above command to cloudmanager. It had files called xxx-api-client-jdk8-1.21.0-SNAPSHOT.pom and xxx-api-client-jdk8-1.21.0-SNAPSHOT.jar at the bottom of the directory tree .... repository/com/xxxx/xxx-api-client-jdk8/1.21.0-SNAPSHOT.
There is also _remote.repositories and maven-metadata-local.xml files, not sure what they are.
I also added the config for the local repository exactly the same as you stated.
Anyhow, I still didn't get any success.
09:51:10,656 [main] [INFO] Downloading from project.local: file:{project.basedir}/repository/com/xxx/xxxxl-api-client-jdk8/1.21.0-SNAPSHOT/maven-metadata.xml

09:51:11,097 [main] [INFO] Downloading from central: https
?
Any ideas?
Thanks Fiona
Uh... I had a typo in config, I'll try again.
You can embed the jar using the following way:
filevault-package-maven-plugin
of all pom.xml like thisThanks,
Nupur
Thanks everyone for your great feedback.
Actually I gave up in the end and manually copied over the files from the API into my project.
But I learned a lot about OSGi and will make another attempt some other time!
