User:Mizdebsk/PackagingGradle

Goals

• package latest Gradle 2.x
• implement local resolver so that packages can be built with Gradle
  • this includes Gradle itself
• package older Gradle from 1.x line, if needed (optionall)
  • some projects won't compile with Gradle 2.x or even incompatible version from 1.x line

TODO

• report usage of non-free JSON library (org.json:json) (http://jira.codehaus.org/browse/XSTR-763)
  • "The Software shall be used for Good, not Evil."
  • android-json-org-java can be used as free replacement
• packaging
  • update to newer version
    • groovy (1.8.x -> 2.3.x, RHBZ #843417)
    • spock-core (RHBZ #1154731)
  • new packages
    • sonar (code quality framework, RHBZ #848096) (msimacek)
    • zinc (incremental Scala compiler)
    • gpars (groovy dep, RHBZ #1163724)
• patching Gradle
  • port to apache-sshd 0.11.0 (uses 0.10.0, minor patch)
  • port to aether-ant-tasks from maven-ant-tasks

Bootstrap plan

Plan for bootstrapping Gradle in Fedora.

People involved: Mikolaj Izdebski

Current state: during phase 4

Phase 1 (initial bootstrap)

• build rpm package containing upstream binaries
• rebuild Gradle from source
  • all dependencies coming from the Internet
• from now on:
  • Gradle can be installed from rpm
  • results: https://mizdebsk.fedorapeople.org/gradle/stage1/

Phase 2 (local mode)

• implement local mode using XMvn
• package all Gradle build dependencies in wrapper rpm
  • binaries taken from the Internet
  • XMvn metadata added
• from now on:
  • Gradle can be built in isolated environment without Internet access
  • new rpm packages can be created which use gradle as build system
  • results: http://copr.fedoraproject.org/coprs/mizdebsk/gradle/

Phase 3 (dependency refinement)

• while wrapper rpm is not empty:
  • pick one artifact from wrapper rpm
  • if it is not yet available in fedora:
    • build it from source and package it as rpm
    • skip tests if there are too many missing test dependencies
    • add any missing build or test dependencies to wrapper rpm
  • rebuild Gradle and run tests to make sure everything keeps working
  • if there are build or test failures, debug them and create patches
• get rid of wrapper rpm
• from now on:
  • Gradle with all dependencies are free from prebuilt binaries
  • everything is patched to work with artifact versions available in Fedora

Phase 4 (push to Fedora)

• request FPC bootstrap exception
• for all new packages:
  • do review (licensing etc)
  • cleanup spec file
  • submit for review
  • someone else reviews the package
  • package is checked into Fedora git and built in Koji
• from now on:
  • we have gradle in Fedora

Phase 5 (further improvements)

• implement javapackages macros for Gradle
• prepare packaging documentation
• announce gradle availability
• upstream patches
• enable tests (if skipped)
