When starting a new Java project recently, I found it surprisingly difficult to setup the Gradle build with support for Java 9 modules and the Kotlin language.
For others who might find themselves in the same bind, here is a gist with the simplest, minimal gradle setup I came up with that includes:
- A multi-project gradle build,
- Java 9 modules support,
- IntelliJ IDEA integration,
- Kotlin language modules with support for cross-references between Java and Kotlin code in the same module.
Here is an proof-of-concept example of the above build scripts in action: https://github.com/nikolaybotevb/gradle-java9-kotlin.
