How to make the aur package into the archlinux community source?

As a maintainer in AUR, I can answer that the only way is to become a member of the famous trusted users of Arch Linux. Which is kinda hard do integrate if you only have one package (just saw your repository).

To quote the official Arch Linux team:

The minimum requirements to becoming a TU are as follows:

• know basic shell scripting
• maintain a few packages in AUR with clean, high-quality PKGBUILDs basic community involvement (mailing list, forums, IRC)
• know Google-Fu
• a general idea of the kind of packages you want to maintain (basically, why do you want to become TU?)

Even though you could become a TU by merely fulfilling those minimum requirements, the people judging you during voting might expect more of you. Such as:

• involvement in the bug tracker (reporting, research, info)
• patches for Arch projects
• involvement in a few open-source projects (even if they are your own)

In between your package have a big problem and I marked it as out-of-date because of the following:

1. According to Arch packaging standard:

   Packages should never be installed to /usr/local

You should install all your files under /usr/share/{pkgName}/* according to the standard.

• package
• archlinux
• pkgbuild
• pacman-package-manager
• xmake
