I have different eclipse installations, luna, mars, neon, 32b and 64b...

All seems to write to my c:/users/mrsimplemind/.eclipse and .p2 folders.

As I don't know how to force each eclipse to write to different folder, like .eclipse45 .eclipse43 etc.

I wonder what can be damaged if different eclipse uses same .eclipse .p2 folders?? Can I delete the .eclipse .p2 folders each run??

(All attempts with settings in eclipse.ini and config.ini didnt solve my issue... I have similar question, but it is about how to change the locations here)

(This question is more about "living with eclipse versions output locations" and instead understand the folders and outputs, and what if delete them!)

  • The .p2 folder is a local cache, it doesn't contain the state of the installation but some cached plugins; so it should be fine to have all Eclipse instances writing/reading here. The .eclipse seems trickier: it usually contains some values for preferences. If you're fine having your preferences shared accross multiple install, it's fine. In any case, most of the state of Eclipse is inside it's `configuration` folder and the workspace state inside the "workspace" folder. What's factorized here shouldn't take control over those 2 directories. – Mickael Aug 29 '16 at 10:50
  • @Mickael thanks for clarify the folders some. The problem is that the eclipse versions are different configured, with different installed plugins etc. I m not sure how sharing same .eclipse and .p2 can f* up things. – MrSimpleMind Aug 29 '16 at 11:05
