We are upgrading a dev environment from 5.6.1 to 6.1 and attempting to use the uber-jar (obfuscated) to build the maven project. I've updated versions on all other dependencies and plugins. I've tried deleting everything under .m2. I've tried what is described here: https://github.com/Adobe-Consulting-Services/lazybones-aem-templates/issues/8. I've looked at all of the forum posts related to the uber-jar and have tried adding in more dependencies but still this error exists. Does anyone have any ideas?

Also - do not forget - you can also use AEM dependency Finder (as opposed to Urber JAR):
http://localhost:4502/system/console/depfinder
I like that tool - it informs you exactly what POM dependency you need.

Try building the GitHub project that is discussed here and uses:
<dependency>
<groupId>com.adobe.aem</groupId>
<artifactId>uber-jar</artifactId>
<version>6.1.0</version>
<classifier>obfuscated-apis</classifier>
<scope>provided</scope>
</dependency>
https://docs.adobe.com/docs/en/aem/6-1/develop/dev-tools/ht-projects-maven.html
https://github.com/scottm2020/aem-uberjar-demo
I just cloned this Github repository and it built successfully:
Here is the Maven result:

Peter, I did read through this and added any dependencies and repositories, plugins, etc. Still I get the same error. I'm beginning to think I need the unobfuscated jar. I've put in a request for it.

smacdonald2008,
The demo project does build for me but my own project still does not. As I said to Peter I'm beginning to think I need the unobfuscated jar.
Our servlets extend sling servlets and the extended class uses SCR annotations but since they were not day or cq/aem classes I didn't think I'd need the unobfuscated jar.
So, maybe we do need it.

"Our servlets extend sling servlets and the extended class uses SCR annotations"
You still need to include POM dependencies for non AEM classes - such as servlets:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
The Urber JAR is for AEM Java classes - such as com.day.cq.mailer.MessageGateway
These are the JAVA APIS that should be covered in the Urber JAR:

Yes, we are including the dependencies for non-AEM libraries like the servlets. I have included the ones mentioned here: http://www.wemblog.com/2014/07/how-to-include-all-cq-dependencies-in.html as well as any from the demo project that I had not already included.

Well, it looks like we are extending the AbstractImageServlet class and using annotations to boot. Not sure why my initial search for this class in our code base didn't find it but it did find it just now. So, I'm assuming based on this that we really do need the unobfuscated jar and I have requested it. After getting it and putting it to use I'll post back if that does resolve my problem.
