If you want to use the settings from “standalone” in the Eclipse plugin just delete the file with the Eclipse plugin settings [user-home-dir]/Application Data/com.oxygenxml.author/oxyAuthorOptionsEc9.3.xml on Windows / [user-home-dir]/.com.oxygenxml.author/oxyAuthorOptionsEc9.3.xml on Linux, start Eclipse and the “standalone” settings will be automatically imported in Eclipse. The same for importing the Eclipse plugin settings in “standalone”: delete the file [user-home-dir]/com.oxygenxml.author/oxyAuthorOptionsSa9.3.xml, start the <oXygen/> “standalone” distribution and the Eclipse settings will be automatically imported.
