My Eclipse distribution does not have the Eclipse Marketplace Client. How can I install Elysium?

Select Help > Install New Software… and install the Elysium feature from the update site http://eclipse.thsoft.hu.

When trying to install, I get the error message Cannot complete the install because one or more required items could not be found. Why?

Make sure the proper update site is available. In Preferences, go to Install/Update > Available Software Sites and add http://download.eclipse.org/releases/juno to the list.

  • -Dfile.encoding=UTF-8 on Linux and OS X
  • -Dfile.encoding=Cp1250 on Windows

Restart Eclipse for the changes to take effect.

Also, on some platforms (e.g. OS X), old versions of LilyPond may not support these files completely, so in this case, you might want to try the latest stable version of LilyPond.
