@simonredfern
please add a webhook to OBP-API:

On GitGub go to repository Settings -> Webhooks & Services -> Add webhook.
Webhook URL: https://jitpack.io/api/webhooks
Content type: application/json

after add this webhook, our OBP-API will automatic install to jitpack maven repository when develop branch have new commit.
other projects can dependent new jar in this way:

    <repositories>
        <repository>
            <id>jitpack.io</id>
            <url>https://www.jitpack.io</url>
        </repository>
    </repositories>
    <dependencies>
        <dependency>
            <groupId>com.github.OpenBankProject.OBP-API</groupId>
            <artifactId>obp-commons</artifactId>
            <version>develop-SNAPSHOT</version>
        </dependency>
    </dependencies>

Hi @simonredfern
There is one warning left not deal with yet:

The reason is this arg is set true:

This arg is for increase compile speed: reference here
maybe someone need this feature to have good compile speed, so I did not change it to "false", It is no harm to our project, what do you think this?
