Build

Currently, you need Maven 3.x & JDK 8 to build the plugin, create the site, and run integration-test.

Commands

• ./mvnw package : generate jar
• ./mvnw site : generate the plugin website
• ./mvnw integration-test : ./mvnw package + run all integration test
  • note: to run test_scalaHome: you have to set scala.home property in src/it/test_scalaHome/pom.xml to correspond to your environment. See Build section above for a simple setup.
• ./mvnw integration-test -Dinvoker.test=test1 : run integration test 'test1' (against all configuration) useful for tuning/debug
• ./mvnw install : ./mvnw integration-test` + publish on local maven repository
• ./mvnw install -Dmaven.test.skip=true : ./mvnw install` without run of unit test and run of integration test
• release :
  • gpg --use-agent --armor --detach-sign --output $(mktemp) pom.xml to avoid issue on macosx with gpg signature see [MGPG-59] GPG Plugin: "gpg: signing failed: Inappropriate ioctl for device" - ASF JIRA
  • ./mvnw release:clean && ./mvnw release:prepare && ./mvnw release:perform : to publish on staging repository via plugin
  • ./mvnw release:clean && ./mvnw release:prepare -Darguments="-DskipTests -Dmaven.test.skip=true" && ./mvnw release:perform -Darguments="-DskipTests -Dmaven.test.skip=true" to publish without tests (integration test require 30min on CI)
  • ./mvnw site package source:jar javadoc:jar install:install gpg:sign deploy:deploy changes:announcement-generate -Dmaven.test.skip=true -DperformRelease=true : manual
  • connect to https://oss.sonatype.org/ close and release the request(about scala-maven-plugin) in staging repositories
  • browse the updated mvnsite (check version into samples, ...)

TODO

• close issues from https://github.com/davidB/scala-maven-plugin/issues/
• refactor :
  • reduce copy-paste
  • file path management can be improved (a lot)
  • clean the code
