Eclipse - How to sort package explorer non alphabetically?

Question

Using eclipse; this is what my package explorer looks like:

I want org.plx to be above com.rs

How can I do this?

I have seen some threads on here with this but nobody has said where and in which menu we can modify whether the explorer is sorted alphabetically or not.

Answer 1

On Eclipse Oxygen (at least) it's possible to workaround that by writing your own package abbreviation rules on

Preferences > Java > Appearance > [x] Abbreviate package names

There, write rules like

org.plx=[A.plx]
com.rs=[B.rs]

or

org.plx=1.plx
com.rs=2.rs
