Could not resolve all dependencies

Support AUR

I am unsure how to resolve this

makepkg -i
==> Making package: packettracer 8.1.1-1 (Tue 24 May 2022 06:05:01 AM MDT)
==> Checking runtime dependencies...
==> Missing dependencies:
  -> java-runtime>=1.7.0
==> Checking buildtime dependencies...
==> ERROR: Could not resolve all dependencies.```

makepkg -si

Or install it using pamac:

pamac build packettracer

Much easier.
