After a decade training Nuxeo developers, I can predict when someone quits: Day three.
They're drowning in diagrams trying to understand document models, schemas, facets, repositories, event buses, lifecycle states, automation chains...
What I wish someone told me in 2013:
Don't try to understand Nuxeo's architecture first. Start with OSGi concepts and solid Java. Everything becomes logical after that.
Real prerequisites:
- Java 11/17/21 (solid skills, not "took a class once")
- OSGi concepts (bundle lifecycle, service registry, extension points)
- REST API mastery
- Polymer 3.x (if touching UI)
Common pitfalls:
- Trying to understand everything before coding
- Ignoring OSGi (then weird classloading errors)
- Fighting the platform vs learning its patterns
- Using Java for stuff Studio generates in minutes
- Not reading logs (they're helpful!)
Full guide covers:
- Week-by-week learning roadmap
- Real-world success patterns with metrics
- Honest "choose if / skip if" assessment
- Code examples and architecture

Happy to answer questions about Nuxeo, OSGi, ECM, or implementation challenges.
