sporadic symlink error (file exists already)

[m-vo]

When ScriptHandler::initializeApplication() gets executed during a composer operation, I've come across this problem (had it two or three times before but unfortunately don't know by what it's caused):

WARNING   ContaoCoreBundle                absolute symlink
WARNING   ContaoCommentsBundle            absolute symlink
ERROR     ContaoNewsletterBundle          Failed to create "web/bundles/contaonewsletter": mkdir(): File exists.

(Output is from a console under windows - so that's why there are absolute symlinks and the warnings are as expected.)

One of the symlinks cannot be created. I don't know why composer tries to create the symlink in the first place as it is already existing and I don't know why the problem only happens for one of the packages.

This might probably rather be a symfony problem than a contao issue as it happens in the assets:install --symlink --relative command.

[aschempp]

is the target an existing symlink or an actual folder?

[m-vo]

An existing symlink.

I now ran vendor/bin/contao-console assets:install --symlink --relative lots of times in a row.

Findings:

• the problem appears quite often. 1 out of 10 or so ;-)
• it's only the newsletter bundle that fails every single time

Is there a way to get more verbose output on the error?

Is there a way to get more verbose output on the error?

Yes, with -v, -vv and -vvv ;)

This never appeared again. I am therefore closing it.
