hg strip vs hg backout and hg revert

What is the difference between the mercurial commands,

• hg strip
• hg backout
• hg revert

All these commands basically are used to revert/undo the effects of an earlier changeset.

hg strip removes the changeset and all its descendants from the repository. It will be as if the changes never existed. Be careful when using this on public changesets as it will not remove it from any other repository and you'll get them back next time you pull.

hg backout creates a new changeset to reverse the effect of an earlier changeset. The old changeset will still remain in the repository but so will a new changeset to remove the changes.

hg revert with a revision updates the working copy to the specified revision. If you then commit that working copy it will have the effect of reverting all changes since.

At certain moment of time I had to build Jenkins pipeline where POM files should be reverted each time the job starts. And the problem which I have faced is: how to revert all POM files reversively.

Since this answer is one of the first on google, I want to contribute my solution for people with same problem

hg revert */pom.xml
