Unfortunately it looks like gradle does not support Java 10 before release 4.2. For the moment I want to focus on getting a new release out. This means I prefer not to make major changes to the build system unless critical for releasing. Once a new release is completed we can revisit the upgrade of gradle as well to fix this and thus support java 10 in the core.
Sorry for the inconvenience :)
