[Bitbucket] [AccessTokenAuth] File name too long

My composer.json:

(secret-key is redacted with .)

            "url": "https://x-token-auth:ATCT............................................................................................................................[e-mail]/the-namespace/module-filter-cms.git"

When I run this command:

php composer.phar require the-namespace/module-filter-cms:dev-master

I get the following output:

And I expected this to happen:
That it installs the dependency without any error.

File name is too long as the username+password contained in the URL is used for the cache-folder as well which is not reliable implementation.

In my case, I have multiple private Bitbucket repos. Each one has a different access token, this is why I cannot make use of auth.json.

I opened a pull request to fix this. Would be great if the merge-commit could be cherry-picked to version 2.2.x and 2.6.x as well.
Thank you <3

Is there a specific reason why you would want to (hard/fixed) integrate the authentication token, in the repository url?

As composer does support authentication config https://getcomposer.org/doc/articles/authentication-for-private-packages.md for private repos. Which saves you having to hard code tokens or alike in your composer.json.

@KevinVanSonsbeek thanks for your input, my issue is that I have approx. 5 private repos, all hosted on bitbucket. Each of those repos do have its own access-token (as per Bitbucket limitations). It is possible to get 1 bitbucket accesstoken for all repos only with their paid Premium-Plan.

I tried lots of things, even with custom Baerer-Authorization header within composer.json, but nothing really worked (except this PR, this one works).

In my case, all developers who have access to the composer.json also have access to the other private repositories so I do not have security concerns in this particular case.
