find revisiting already visited folder

Question

When using below command to list folders as they get deleted

$ find . -type d -name .idea -exec sh -c "echo {}; rm -rf {}" \;
    ./.idea
    find: ‘./.idea’: No such file or directory
    ./folder1/.idea
    find: ‘./folder1/.idea’: No such file or directory
$

no idea why deleted folders are being revisited by find producing error of

No such file or directory

Answer 1

find processes each directory's contents after the directory itself.

So you need to add -depth option :

find . -depth -type d -name .idea -exec sh -c "echo {}; rm -rf {}" \;

Update

You can do following expriment, first

mkdir -p .idea/folder1/.idea

# Step 1
find . -type d -name .idea -exec sh -c "echo rm -rf {}" \;
# rm -rf ./.idea
# rm -rf ./.idea/folder1/.idea

# Step 2
find . -depth -type d -name .idea -exec sh -c "echo rm -rf {}" \;
# rm -rf ./.idea/folder1/.idea
# rm -rf ./.idea

You can see that in step 1, find first removes ./.idea and then tries to search the subdirectories to find ./.idea/folder1/.idea.

Whereas in step 2, find first tries to search the subdirectories to find ./.idea/folder1/.idea and removes ./.idea after that.
