推荐答案

你需要在 files 标签中包含这些文件，像这样:

You need to include these files in files tag, like this:

<files>
    <!-- The others files that you added -->
    <filename>sql/mysql/install.mysql.utf8.sql</filename>
    <filename>sql/sqlazure/install.sqlazure.utf8.sql</filename>
    <filename>sql/mysql/uninstall.mysql.utf8.sql</filename>
    <filename>sql/sqlazure/uninstall.sqlazure.utf8.sql</filename>
    <filename>sql/sqlazure/updates</filename> <!-- Not sure about this one, sorry -->
</file>

我也在学习，我不知道更新文件是否需要添加文件标签.将此与 Lodder 的回答结合起来.希望有用.

I'm learning too and i don't know if the updates file is necessary to add on files tag. Combine this with Lodder's answer. Hope be useful.
