How to only build one directory in a pipeline job?

[Mark Allison]

I have a github repo called multibranch-test with two sub-directories Project1, Project2.

PS C:\Repos\multibranch-test> tree .
Folder PATH listing for volume Windows
Volume serial number is 2085-6D3D
C:\REPOS\MULTIBRANCH-TEST
├───Project1
└───Project2

Each sub-directory has a Jenkinsfile and the code for that project.

I Jenkins I have two multibranch pipeline jobs - one for Project1 and one for Project2. In the configuration for Project1 I don't want a push notification or polling to build Project1 if a commit was pushed in sub-directory for Project2.

So in Project1 I have configured Additional Behaviours:

Advanced clone behaviours

    Shallow clone is checked

Sparse checkout path is set to Project1

Polling ignores commits in certain paths

   Included Regions: Project1/*

   Excluded Regions: *

Build Configuration

    Script Path: Project1/Jenkinsfile

What is happening is if I push a commit to master in sub-directory Project2, Project1 and Project2 jobs get built. I only want Project2 to build. Can someone point out what I'm doing wrong?

Jenkinsfiles for both Projects are similar and look like:

#!groovy
	node {
	stage ('checkout') {
	checkout scm
	}
	stage ('build') {
	dir ('Project1') {
	bat 'powershell -Command gci'
	bat 'powershell -Command gci env:'
	bat 'powershell -File .\\Project1.ps1'
	}
	}

I just noticed a potential bug.

I changed these:

   Included Regions: Project1\/.+

   Excluded Regions:

It's still building both projects. Anyone got any ideas?
