Bundled AsyncUDP has invalid library.json

[andig]

I'm trying a cross-build for esp8266 and esp32 both. I need to use ESPAsyncUDP.

In order to have the esp32 build NOT use the ESPAsyncUDP but the built-in AsyncUDP, I've set lib_compat_mode=strict.

[env:esp32]
platform=espressif32
# use stage version for added SPIFFS support
#platform=https://github.com/platformio/platform-espressif32.git
board=featheresp32
framework=arduino
lib_compat_mode=strict
lib_ldf_mode=deep
lib_deps=
    ${common.lib_deps}
    ESP Async WebServer@^1.2
#    https://github.com/me-no-dev/ESPAsyncWebServer
    https://github.com/me-no-dev/AsyncTCP
    AsyncUDP
    SPIFFS
    FS

Problem is that now the AsyncUDP is ignored according to the verbose build:

LDF MODES: FINDER(deep) COMPATIBILITY(strict)
Platform incompatible library /Users/andig/htdocs/SimpleEVSE-WiFi/.piolibdeps/ESPAsyncTCP_ID305
Platform incompatible library /Users/andig/htdocs/SimpleEVSE-WiFi/.piolibdeps/ESPAsyncUDP_ID359
Platform incompatible library /Users/andig/htdocs/SimpleEVSE-WiFi/.piolibdeps/MFRC522_ID63
Platform incompatible library /Users/andig/.platformio/packages/framework-arduinoespressif32/libraries/AsyncUDP

Looking at the platform directory I see that libraries/AsyncUDP contains this library.json:

{
"name":"AsyncUDP",
"description":"Asynchronous UDP Library for ESP32",
"keywords":"async,udp,server,client,multicast,broadcast",
"authors":
{
    "name": "Hristo Gochkov",
    "maintainer": true
},
"repository":
{
    "type": "git",
    "url": "https://github.com/me-no-dev/ESPAsyncUDP.git"
},
"frameworks": "arduino",
"platforms":"espressif"
}

This seems wrong twice- I assume the platform should be "espressif32" and wrapped inside an array or the library.json removed altogether. The latter would limit confusion as it still points to the ESPAsyncUDP repo.

Btw, frameworks should also be an array?
