Java

Configuration Example

[project]
name      = "my-java-app"
root      = "."
languages = ["java"]

[resolve.java]
module_name = "com.example.myapp"

[[layers]]
name            = "domain"
paths           = ["src/domain/**"]
dependency_mode = "opt-in"
allow           = []
external_mode   = "opt-out"

[[layers]]
name            = "usecase"
paths           = ["src/usecase/**"]
dependency_mode = "opt-in"
allow           = ["domain"]
external_mode   = "opt-out"

[[layers]]
name            = "infrastructure"
paths           = ["src/infrastructure/**"]
dependency_mode = "opt-in"
allow           = ["domain"]
external_mode   = "opt-in"
external_allow  = ["java.util.List", "java.util.Map"]

mille init Behavior

Reads pom.xml (Maven) or build.gradle + settings.gradle (Gradle) and auto-sets module_name. Layer paths use **/layer/** globs to match regardless of source root depth (e.g. Maven’s src/main/java/com/example/myapp/domain/).

Inferred layer structure:
  domain               ← (no internal dependencies)
  infrastructure       → domain
    external: java.util.List
  usecase              → domain
  main                 → domain, infrastructure, usecase
