Composer: The package is not available in a stable-enough version error - I do not understand
<p>I have a little problem. I created a repository on Github. It has two branch: <code>master</code> and <code>1.1</code>. </p>

<p>This is the first time when I require my repository.</p>

<p>So I want to get this repository into another project. So I extended the <code>composer.json</code> with my github repo name: </p>

<pre><code>    "require": {
        // ...
        "botalaszlo/symfony-repositemap-bundle": "dev-master"
    },
    "minimum-stability": "dev"
</code></pre>

<p>But unfortunately I got always a composer error:</p>

<pre><code>Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package botalaszlo/symfony-repositemap-bundle could not be found in any version, there may be a typo in the package name.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see &lt;https://getcomposer.org/doc/04-schema.md#minimum-stability&gt; for more details.

Read &lt;https://getcomposer.org/doc/articles/troubleshooting.md&gt; for further common problems.
</code></pre>

<p>Then I checked the package name, it is fine: copy-paste :)
But the <code>minimum-stability</code> problem I do not understand, I think I misunderstand something because I read the links and I still do not find the problem in my settings in composer.json. (However I am tired...).</p>

<p>Then I tried with the <code>"@dev"</code>, <code>"*"</code>, and with the <code>"1.1"</code> values. But always the same problem.</p>

<p>Finally I run the <code>composer diagnose</code> command, but it does not see any errors.</p>

<p>Thank you for the help.</p>
