For some reason I needed to disable the Spring auto reconfiguration:
JBP_CONFIG_SPRINGAUTORECONFIGURATION needs to be set to [enabled: false]
Otherwise I get:
The application or context root for this request has not been found: /

Use the gradle wrapper (gradlew) and you don't even need to install Gradle.
Note that push does not build, so you need to build then push using: gradlew build cfPush
:cfPush

Add an Internet of Things IBM service and bind it directly when creating it Add Service -> App: 'bluemix-boot' -> Service Name: 'bluemix-mqtt' -> Selected Plan 'Free' -> Create The service should then both be created and bound to the bluemix-boot app. The trick that took me forever to understand was to add the following section to the CF gradle plugin:
services {
'iotf-service' {
label = 'iotf-service'
plan = 'iotf-service-free'
name = 'bluemix-mqtt'
bind = true
}
}
This is taken from the credentials section on the service found in the dashboard. The VCAP_SERVICES environment variable contains a JSON describing all bound services including their credentials. This is used directly in the creation of the Camel route to avoid having to hard-code or configure the credentials. The Spring Cloud might contain things that could be used for this instead but this was the simplest way to get it in place as of now. Think it will be cleaner to put this in ApplicationConfig.groovy later.
Read the docs how to add a device in the IoT console. Notice the syntax for allowed values in the topic string. Simple IoT groovy client
Seems like the Liberty buildpack adds its own management stuff, so Spring actuator might not be needed. Unless more is more? Spring Reference: endpoints
