processing the DELETE BRANCH message from GH after the GH Branch is deleted

[ghost]

ok so the idea here is ... I'm in Github and I press "Delete Branch" and the message makes it to Jenkins BUT because the Github branch is already gone nothing interesting happens (rightly so the branch is gone ... it was just deleted) ---> BUT !!!! there's nothing saying I can't invoke a pipeline on a DIFFERENT BRANCH that contains clean up code.

Where I'm going with all this is I have a branch (call it INFRASTRUCTURE_CLEANUP) and that branch NEVER goes away (well it better not) as it contains pipeline code to cleanup infrastructure. When I delete ANY OTHER BRANCH of the same project I want my INFRASTRUCTURE_CLEANUP branch called.

As a side note ... I'm on the fence about "synchronizing" the doRun(String branch) method (cause synchronizing an entire method IS BAD !). Anyways I put a big comment in front of the method ... and I apologize if my coding is less than par. Trust me I'm trying my best so guidance is appreciated !

#248 I think event arguments can't handle verification... they need know branchName...

[ghost]

Im stuck I don't understand the build failure ...

https://travis-ci.org/KostyaSha/github-integration-plugin/builds/309844133?utm_source=github_status&utm_medium=notification ->>>

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project github-pullrequest: Compilation failure [ERROR] /home/travis/build/KostyaSha/github-integration-plugin/github-pullrequest-plugin/src/main/java/com/github/kostyasha/github/integration/branch/GitHubBranchTrigger.java:[236,60] cannot find symbol [ERROR] symbol: variable branch [ERROR] location: class com.github.kostyasha.github.integration.branch.GitHubBranchTrigger

but when I look at the code I don't see how it's undefined ... :( Line 236 is within a method that clearly identifies the variable "branch" on the method signature :

private List<GitHubBranchCause> readyToBuildCauses(GitHubBranchRepository localRepository,
                                                   LoggingTaskListenerWrapper listener,
                                                   @Nullable String branch) {

oops ... i synce with the fork ... and now I see it ...

master has bit refactored code, it should help to handle delete case. Master contains skeleton of multibranch implementation. Unfortuantely multibranch (scm-api & branch-api) can't support delete events, has conflict on FS when branch name matches to pr-xxx name. New multibranch API is broken by design....

Arriving late to the party... This plugin works well when branches are created (I'm using cron polling not webhook), but not detecting deleted branches is a hindrance for my use case, automated creation and destruction of staging server instances. For this reason, I need to manually stop and remove containers. As soon as you have a preliminary fix let me know to give it a try. Thanks.
