If this happens, it is a sign of a poorly designed plug-in.

By design .project and .cproject should be portable, and ideally the plug-ins should not store non-portable definitions there.

random() followed by a uniqueness check.

CDT generally generates these IDs at project creation time and does not change them during the project lifetime (unless very special cases or rather poorly designed plug-ins).

I did some translators between CDT and other build systems (for example mBed, xPacks) and I played with these details.
