Eclipse code formatting and (basic) project configuration files can be found at the etc/ folder. You should manually
copy them after importing all your projects:
for settings_dir in `find . -type d -name .settings`; do
\cp -v etc/ide-settings/eclipse/org.eclipse.jdt.* $settings_dir
done
Do not use the maven-eclipse-plugin to copy the files as it conflicts with m2e.
If you completed the step described on idea instructions, and selected the code style accordingly you should be ready to go.
For editors supporting EditorConfig, a settings file is provided in etc/ide-settings/editorconfig.ini. Copy it to your Artemis top level directory and name it .editorconfig
