Setting different spaces for tab for Java and Scala in Eclipse

Question

In Java, the usual convention is to have tab size 4. In Scala it's 2. In a Scala + Java project, is it possible to set these different tab sizes, depending on the language file?

Answer 1

Windows > Preferences > General > Editors > File Associations

Find *.scala in the list and ensure Scala editor is selected as the first option. if it is, then we just need to change the preferences for the scala editor.

Then:

project > properties > Scala formatter

The either select project specific settings or workspace specific settings, there should be an option where for how many spaces you want.
