The reserved indicator "@" cannot start a plain scalar about cachebundle HOT 4 CLOSED

What version of Symfony are you trying to run this under? I tried linting the yaml file with Symfony 2.8's built-in linter and it declared the file valid. After that I tried installing it in a symfony 3.0 project and composer freaked out and wouldn't let me, so the bundle currently appears not to be compatible with Symfony 3.0.

The symfony 3.0 linter did present the same errors you're seeing, but the fact that composer can't install the bundle under SF3 indicates that more work is needed overall before it can support SF3.

I have version 2.8 currently.
Bundle works perfectly in dev and prod except of PHPUnit part where all tasts failing becourse of this Notice-like message.
Also in manual page all examples argument with service are quoted.

OK, I've pushed an update into the master branch, please let me know if this fixes the issue.

Now all works without any problems.
Thank you for your help.
