A while ago I posted the question below to the incubator mailing list. I
wanted to get an entity to use runtime files from a resource in one of its
libraries but found that Brooklyn was unable to resolve it.
I recently had a chance to discuss the problem in more detail with Svet and
learned the solution.
Here's an example catalogue entry from a test in Brooklyn with the solution
in bold:
brooklyn.catalog:
id: vanilla-software-resource-test
version: 1.0
item:
services:
- type: org.apache.brooklyn.entity.stock.BasicApplication
brooklyn.children:
- type: *java:*
org.apache.brooklyn.entity.software.base.VanillaSoftwareProcess
brooklyn.config:
launch.command: true
checkRunning.command: true
# Contained in brooklyn-test-osgi-entities.jar.
runtimeFiles:
classpath://org/apache/brooklyn/test/osgi/resources/message.txt: message.txt
libraries:
- classpath://brooklyn/osgi/brooklyn-test-osgi-entities.jar
In case the formatting is lost the key point is the "java:" at the front of
the VanillaSoftwareProcess type. Without this Brooklyn is unable to resolve
message.txt.
