TL;DR: mvn verify should build a p2-accessible repository in repository/target.

Development

This project is built using Maven Tycho, a set of extensions to Maven for building Eclipse bundles and features.

Requirements

  1. Maven 3.1.1 or later. Although m2eclipse is bundled with its own Maven install, Maven is necessary for command-line builds.

  2. JDK 8

  3. git (optional: you can use EGit from within Eclipse instead)

  4. The Eclipse IDE. It's easiest to use the Eclipse IDE for Java EE Developers package. You can use Eclipse 4.7 (Oxygen).

    1. The m2eclipse plugin (also called m2e) is required to import the projects into Eclipse. m2eclipse is included in several packages, such as the Eclipse IDE for Java EE Developers package.
  5. Clone the project to a local directory using git clone git clone ssh://username@git.eclipse.org:29418/lsp4e/lsp4e.git.

Configuring Maven/Tycho Builds

The plugin is built using Maven/Tycho and targeted to Java 8.

Changing the Eclipse Platform compilation and testing target

By default, the build is targeted against Eclipse Oxygen / 4.7. You can explicitly set the target-config property to target-platform-oxygen (4.6) or target-platform-photon (4.8).

$ mvn -Dtarget-config=target-platform-photon verify

Import into Eclipse

Prerequisites:

  1. You have installed Eclipse for RCP and RAP Developers 4.7 or later. Other distributions that include PDE and reasonable Java support may also work.

  2. You have cloned the lsp4e repo into a local directory.

In Eclipse:

  1. File > Import > Existing Maven Projects

  2. Click Next.

  3. In the Root Directory chooser select the directory where you cloned the project, and which contains pom.xml.

  4. All targets should be selected. Click Finish.

  5. At this point the Problems view should show on the order of 1000 errors.

  6. In the Project Explorer, select the file target-platform-photon.target. Open this file with the target editor.

  7. Click the "Set as Target Platform" link on the top right.
