Problem

The deployment of a new service builder module works fine, but the service isn't registered. There is no entry in the json web api and if you use a ServiceUtil, a NullPointerException is thrown.

Sometimes it's possible to deploy and use it once, but after a change in the ..LocalServiceImpl.java or ...ServiceImpl.java, the methods aren't available any more.

Solution

Replace compileOnly with compile in the file build.gradle in the -service project.
Refresh the api module after the deployment (GoGo Shell). This is only necessary, if a method signature in the ...LocalServiceImpl.java or ...ServiceImpl.java has changed, added or removed.

Environment

Windows and Linux, Gradle 3.0, blade version 1.0.5.201609070324
