Thanks for those details @vrubezheny! It would be great if you could add such hints directly into some CONTRIBUTING.md file.

In general, you need:

  • openjdk-11 (with sources) installed ,
  • Eclipse SDK + eclipse-test-framework-4.16.zip
  • cd ~/projects/ (or whereever you save your projects) git clone https://github.com/eclipse/wildwebdeveloper.git (if needed) git clone git://git.eclipse.org/gitroot/lsp4e/lsp4e.git
  • some really simple test project with json schema (like described above)
  • Install Eclipse, install eclipse-test-framework into it (might help in building/running tests), import (in simple case) all wildwebdeveloper plugin projects, (if needed) you might import all jsp4e plugns.
  • Build WWD Target Platform (cd ~/projects/wildwebdeveloper/target-platform/; mvn clean install;) and set it as your Eclipse’s target platform (open in Eclipse wildwebdeveloper/target-platform/target-platform.target file and check it’s installed in Window - Preferences -> Plug-in Development -> Target Platform preference page.
  • Build WWD itself (cd ~/projects/wildwebdeveloper//; mvn clean install;)
  • Create Run/Debug 'Eclipse Application" configuration and start it.
  • Then, in started application, create or import some simple test project (with json schema and a yaml file) and configure in `Window -> Preferences -> YAML -> YAML Schemas’ your schema and a global pattern.
  • That’s it… You can open your yaml file in editor and see the server logs.
  • One more thing to configure: yaml server logs: Window -> Preferences -> Language Servers -> Logs, enable the required either Log to File or Log to Console or both. There will be a new project created in your workspace named after languageServers-log - you may find a link on the same preference page. Also, you can import it into you workspace and always have the logs handy. Quite simple 😃
