OpenDaylight Developers Experience 1.5: Eclipse Setup, HOT reload, future plans
0 likes1,068 views
The OpenDaylight SDK presentation, delivered by Michael Vorburger, addresses challenges faced by developers, particularly regarding Eclipse compile errors due to incompatibility with specific Maven plugins. It offers insight into tooling and features available to facilitate OpenDaylight development, including various plugins and editor functionalities, and provides guidelines for improving code quality and build performance. The presentation also touches upon considerations for project management in IDE environments and future development enhancements.

OpenDaylight Developers Experience 1.5: Eclipse Setup, HOT reload, future plans

- 5. 1.
- 6. 1.Help - I still have Red X's! (i.e. Eclipse compile errors) “Eclipse is no longer able to compile OpenDayLight. The reason is three maven plugins which are used by OpenDayLight but are not integrated into Eclipse: maven-plugin-plugin, karaf-maven-plugin and maven- antrun-plugin. This means you will always have Eclipse compile errors in the project (this could go to up to 100000 errors). You can use Eclipse for editing easily but to compile the project you need to open a terminal window and do the compilation (...)”
- 8. And you just wanted to contribute your very first open source bug fix today, not get a black belt in IDE- ology!
- 12. +10’
- 14. What’s in it for you? • git clone, import • Working Set (dyn) • MAGIC (m2e) • 20+ Plugins • 20+ Preferences • YANG Editor • Goodies
- 15. YANG IDE • Builder • Folding • Validation • Doc Hover • Formatting • Highlighting https://github.com/xored/yang-ide/wiki/Features • Code Completion • Comment Toggle • Navigation (F3) • Templates • Outline
- 17. Eclipse Tips • Don’t disable Auto Build • No separate workspaces • Red? Alt-F5 (mvn), not clean • If too much auto. rebuilding? Consider closing projects. (Note: Open/Close is also available on Working Sets.) FYI: ODL projects needed adjustments to previously done M2E lifecycle mapping, for correct in-IDE build. Your project’s pom.xml may also need tweaks; raise it on dev list, or IRC/email me, if unclear.
- 18. Code Quality (IDE?) Bug prevention (incl. security); uniformity lowers friction

- 31. 1. mvn [-o] clean install 7:41 min 2. mvn [-o] -Pq install 1:16 min
- 32. -Pq mvn -Pq install skips: • Tests compilation • Unit tests running • Karaf features testing • Integration tests running • Coverage instrumentation (Jacoco) • FindBugs analysis • Checkstyle analysis • JavaDoc generation • Source JAR building • Maven site building • Invoker, Enforcer https://git.opendaylight.org/gerrit/#/c/40245/
- 34. bundle:watch * Shift-Alt-X-M -Pq -o -DaddInstallRepositoryPath= -Pq = Quick. This ^^^ is another Q.. https://git.opendaylight.org/gerrit/#/c/40520/
- 36. What NeXT ? • HOT • WS Build Performance? • Checkstyle: ++Adoption; (incl. refinements, if needed) • FindBugs? Null analysis? • Bndtools? The OSGi IDE: • Instant bundle JAR builder • Semantic Versioning, in IDE... • Launchers for lightweight in- container FAST OSGi integration testing (Karaf?) • bnd.bnd ⇐ pom.xml (mvn?) bnd-based; ODL already uses, via maven-bundle-plugin.
- 38. BACKUP SLIDES Not used in the 30’ presentation (too much)
- 42. • • •
- 50. • • • • VS JVM hot code replacement (HCR), with karaf -debug? 1. Limitations! Really only swaps method bodies. 2. WS vs. JAR out-of-sync Others? See list on https://github.com/vorburger/hotea .. IMHO, simple bundle classes reload is best. OSGi is dynamic! (Theory VS Practice)
