Scan and pick an available port, for other grunt tasks

grunt-port-pick's Issues

Ports are not removed from "try port list" when assigned

I have a pretty complex portPick configuration since my grunt task needs to start a lot of services in a Jenkins CI job. If the first target in the list has a port assigned (say 8080), then obviously 8080 is being attempted first. When this succeeds, port 8080 remains in the tryPorts-list, and the next target (with, or without a default port) will get 8080 assigned as well, etc.

So now all my services attempt to run on port 8080, which obviously fails. I can only use this task when no default port has been assigned to any of the targets (or just the last one).

An example config:

module.exports = {
    options: {
        port: 9080
    },
    connectDev: {
        targets: ['connect.dev.options.port']
    },
    connectTest: {
        targets: ['connect.test.options.port']
    },
    stubby: {
        targets: [
            'stubby.dev.options.stubs',
            'connect.dev.proxies.port'
        ]
    },
    stubbyTls: {
        targets: ['stubby.dev.options.tls']
    },
    ....

So, if connect.dev.options.port has been defined as port 8080, then all portPick will do is assign port 8080 to all targets mentioned here.

Even if stubby.dev.options.tls would have a default value of 8000, it would still get port 8080 assigned.
