EventPublisher, spring-scanner and remote bamboo agents

[Deleted user]

I am attempting to integrate into an existing plugin in order to send e-mails based on some internal business logic using Atlassian's EventPublisher API which I am wiring from atlassian-spring-scanner v1 API.

Using the latest Atlassian sdk, I was successfully create a plugin in order to do so on a local build agent.  Unfortunately, when I attempted to do the same thing on a remote build agent, I was unable to do so.

INFO | jvm 2 | 2018/01/21 21:28:54 | 2018-01-21 21:28:54,256 ERROR [remoteEventRebroadcasterMessageListenerContainer-1] [OsgiPlugin] Plugin 'com.hidden.notifications' never resolved service '&eventPublisher' with filter '(&(objectClass=com.atlassian.event.api.EventPublisher)(objectClass=com.atlassian.event.api.EventPublisher))'

I'm pretty sure my issue is as described in the following post which states that this API (and ApplicationProperties which I also tested) are not available on the remote agent classpath.

Unfortunately, the work arounds mentioned will not work for me since I can't just pipe the data -- I need to use the capabilities of the EventPublisher API to send e-mails.  I also can't create a custom EventListener to run on a local agent as I am dependent on deployment events which I don't believe Bamboo supports.  Even if it does, I'd rather not go down this path as the business logic for sending e-mails would be dependent on several runtime variables.

Is there any other work around for what I would imagine could be a fairly common usecase in order to send e-mails using Atlassian's EventPublisher API from remote agents.  My last resort was to create my own service.  Thank you.

UPDATE:  This turned out to be a firewall issue so my work around for using a separate e-mail service does work.  I'd still prefer to use Atlassian's EventPublisher API if at all possible from a remote agent.

I also ran into issue when attempted to create a separate e-mail service using the javax.mail.api.  This works fine locally but when running from the remote agent I see this.  I did verify that the bamboo server has connectivity to the SMTP server so perhaps the remote agent is blocking port 25.

My next step which I am very reluctant to do is to create a REST API which would run on the main bamboo service to accept e-mails sent via JSON from the remote agents.  Please tell me there is an easier way.
