Prevent Visual Studio Code from inserting import statements in Java code

While I have not personally used the Extensions Pack for Java, I do know that within File > Preferences > Settings, you can search for specific settings. Searching for "Import" or "Auto" within settings should pull up any settings related to the features added by these extensions.

Settings search example

If you aren’t able to find the source of the problem, then unfortunately the authors of said extensions did not easily add a way to configure this functionality, and you may need to toggle on/off each added extension to figure out which one is specifically causing the issue, and if you’re able to continue without that specific extension. Hope this helps!
