The old .idea/codeStyleSettings.xml
is imported to two new files: .idea/codeStyles/codeStyleConfig.xml
containing a link to preferred project code style and .idea/codeStyles
/Project.xml
with code style settings for different languages. The latter is optional and is created only if there are non-default settings. If .idea
directory is under version control, both files can be added to VCS too. The old codeStyleSettings.xml
is kept for backwards compatibility.
