Development environment setup
Download and unpack Eclipse latest SDK Kepler build from http://download.eclipse.org/eclipse/downloads/ . The instructions below assume fresh/clean Eclipse installation.
Install m2e 1.4 or newer from http://download.eclipse.org/technology/m2e/releases .
Clone m2e-core repository. Committers should use ssh://YOUR_COMMITTERID@git.eclipse.org:29418/m2e/m2e-core. For other ways to access m2e git repository, including read-only anonymous access see https://git.eclipse.org/r/#/admin/projects/m2e/m2e-core
Import m2e-core as existing maven project. Follow onscreen instructions, allow m2e to install additional software and restart eclipse when requested. Give Eclipse some time to update project configuration after restart. You may need to do Project/Clean.../Clean_all_projects to clear all compilation errors.
Clone m2e-core-tests repository. Developers should use firstname.lastname@example.org:tesla/m2e-core-tests.git. See https://github.com/tesla/m2e-core-tests for other ways to clone m2e-core-tests repository.
Import m2e-core-tests as existing maven project.
Running m2e automated regressions tests from Eclipse
Add the following memory configuration parameters to JVM startup options
Use JUnit_Plug-in_Tests launch configuration type to run/debug m2e automated regressions tests from Eclipse.
Caveat. Two tests are expected to fail when run from Eclipse
- ProjectRegistryManagerTest#testEnvironmentVariablesConsidered requires TEMP environment variable to be set and is expected to failed when run from Eclipse.
- MarkerTest#test is rather sloppy and requires elaborate launch configuration setup to limit set of m2e extensions enabled during the test.
Both tests are expected to pass on command line (see instructions below).
Building m2e on command line
Building m2e on command line is a two step process, both performed from root of m2e-core checkout directory
First, you need to *install* m2e maven runtime to local maven repository
mvn clean install -f m2e-maven-runtime/pom.xml
Then, package m2e update site
mvn clean package
The repository is created under org.eclipse.m2e.site/target/repository directory.
Running m2e automated regression tests on command line
To run m2e automated regression tests, execute the following command from m2e-core-tests checkout directory
mvn clean integration-test -Puts,its -Dm2e-core.url=file://<full-path-to-m2e-repository>
m2e only accepts changes contributed via Gerrit. Here is the wiki that explains how to use it http://wiki.eclipse.org/Gerrit . Good luck.
According to eclipse legal poster, all contributors must have signed Eclipse CLA and their bugzilla email and git commit author must match (otherwise Eclipse git server refuses contribution).
Note that m2e developers do NOT watch Gerrit submissions directly. All contributions must be referenced from corresponding bugzilla records.
