jni plugin requires jdk to have awt.

[bsutton]

I've just added the cronent_http package to my app which I'm testing on linux (ubuntu).

From my understanding cronet_http uses jni and I can see the generated_plugings.cmake file (under linux/flutter) has been updated to include 'jni' as a plugin.

list(APPEND FLUTTER_FFI_PLUGIN_LIST
  jni
  pdfrx
)

The problem is that when I do a linux build I'm getting the following error:

flutter build linux
Changing current working directory to: .../git/pigation2/pig_app

CMake Error at /usr/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

I believe the problem is that I have openjdk-headless installed which doesn't included awt.

Given I can't imagine a scenario where someone would be trying to access awt via jni (would it even work) it would be good to remove the awt check from the make script.

@HosseinYousefi does package:jni check for the presence of AWT?

[HosseinYousefi]

No, it doesn't. Apparently if I add

set(JAVA_AWT_LIBRARY NotNeeded)
set(JAVA_JVM_LIBRARY NotNeeded)
set(JAVA_INCLUDE_PATH2 NotNeeded)
set(JAVA_AWT_INCLUDE_PATH NotNeeded)

to cmake, it should fix it. I will open a PR tomorrow.

Awesome, thank you!
