Tips & Gotchas

Blueprint XML

• The persistent-id attribute value in the property-placeholder element shouldn't have a .cfg suffix.
• If you set update-strategy to reload, the bundle automatically picks up and applies changes to the cfg file.

camel-karaf-maven-plugin

• To use mvn camel-karaf:run you first need to mvn install the module.
• Changes won't be automatically detected, so you need to make sure you run mvn install again.
