Handling environments : how to revert unwanted modifications

Hello,

I'm working on a composite project and I use several environments. I previousely had many of them (depending on the target machine endpoint) and I removed them.

Recently I created a new environment for a single-shot test and then deleted it. However, when it comes to commit the modifications related to the tests done I have more than 2000 files that are modified. I realized that all of them have been set with the new environment id even though this one has been deleted.

Having a look to the settings.xml file at project level I realized that I have 21 environments set though I kept only 3 of them.

I can see that each single file has data for all the environments, even the deleted ones.

 

Is there a possibility to erase this unwanted data easily ?

why soap ui does not erase this when environments are deleted  ?

 

thanks for any help
