JVM library

Use the jvm/lib product type in a module to build a JVM library.

Module layout

Here is an overview of the module layout for a JVM library:

my-module/
├─ resources/ # (1)!
│  ╰─ logback.xml # (2)!
├─ src/
│  ├─ lib.kt
│  ╰─ Util.java # (3)!
├─ test/
│  ╰─ LibTest.java # (4)!
│  ╰─ UtilTest.kt
├─ testResources/
│  ╰─ logback-test.xml # (5)!
╰─ module.yaml
  1. Resources placed here are copied into the resulting JAR.
  2. This is just an example resource and can be omitted.
  3. You can mix Kotlin and Java source files in a single module, all in the src folder.
  4. You can test Java code with Kotlin tests or Kotlin code with Java tests.
  5. This is just an example resource and can be omitted.

If you're migrating from Maven, you can also configure the Maven-like layout
