mail-it

Open source e-mail service featuring template management and processing

Building mail-it

Requirements

  • JDK 17
  • Kotlin 1.8
  • GraalVM 22.3 (for native build only)
  • Node.js 18
  • Docker (for tests only)

Building artifact

To build the artifact run the following command:

./gradlew clean distribution:build \
  -Dquarkus.package.type=${PACKAGE_TYPE} \
  -PdatabaseProvider=${DATABASE_PROVIDER} \
  -Pconnectors=${CONNECTORS} \
  -PwithUi

To skip tests replace distribution:build with distribution:assemble

Variable name Description
PACKAGE_TYPE Type of result artifact. Possible values are uber-jar or native (graalvm is required)
DATABASE_PROVIDER Database that will be used by this application. Possible values are h2 (set by default), mysql and postgresql
CONNECTORS List of connectors for this application. Only http is supported (set by default)

Please, note that h2 database runs in embedded mode only, thus all data is lost on every application restart, so this mode is appropriate only for dev purposes. Also, native packaging doesn't support h2 database

Resulting artifact path is distribution/build/mail-it-VERSION-runner.jar in case of uber-jar or distribution/build/mail-it-VERSION-runner in case of native
