PlatformIO goes into (almost) infinite loop updating configuration

PlatformIO IDE
1

I have a project with numerous environments defined in platformio.ini.

Almost every time I update platformio.ini or do a compile, PlatformIO goes into an infinite loop updating the configuration. Very strange. Especially since it’s installing a library that isn’t called for in the selected environment.

[env]
  build_src_filter = -<*.*>
  framework = arduino
  monitor_filters = time
  monitor_speed = 115200
  build_flags =
    -D DEVELOPMENT_MODE
    -D ENABLE_FUNCTION_TRACING
    -D ENABLE_SERIAL_PRINT

[env:feather_32u4_base]
  extends = env
  platform = atmelavr
  board = feather32u4
  upload_port = /dev/cu.usbmodem1442401
  monitor_port = /dev/cu.usbmodem1442401

[env:mac_address_test_32u4]
  extends = env:feather_32u4_base
  build_src_filter = +<macAddressTest.cpp>
  build_flags =
    ${env.build_flags}
    -D MAC_ADDRESS_PRINTABLE
    -D MAC1="0x02, 0x44, 0x50, 0x01, 0x00, 0x01"
    -D MAC2="0x024450010002"

Here is the output from the config operation:

Resolving mac_address_test_32u4 dependencies...
Library Manager: Installing arduino-libraries/Ethernet @ ^2.0.0
Unpacking 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100%
Library Manager: Ethernet@2.0.2 has been installed!
Already up-to-date.
Updating metadata for the vscode IDE...
Configuration process has been terminated!

As you can see, it’s installing the Ethernet library which is not listed as a dependency for the environment.

After displaying that message, the notice in the lower-right goes away and a few seconds later it comes back and repeats the process.

It will eventually error out with a “too many something or other request” error.

What on earth is causing this and how do I fix it?

TIA,

D.

Do you have any library installed in the lib/ folder of your project?

Do you have a global library installed in C:\Users\<user>\.platformio\lib?

What is the first few lines of the output of project tasks → Advanced → Verbose Build?

I have a number of libraries in lib/.

I do not have anything in ~/.platformio/lib (that directory doesn’t even exist).

What do either of those have to do with this problem?

Thanks.

4

What is their manifest? (library.properties, library.json)?

PlatformIO shouldn’t just decide to install arduino-libraries/Ethernet by itself, some library or script must be instructing it to do it.

Ah. Yep one of my libraries was specifying Ethernet as a dependency in library.json.

That doesn’t explain the infinite loop, though.

Ideas on that?

Thanks.

Distill it into a minimal reproducable example and post it to https://github.com/platformio/platformio-core/issues/ to get it investigated.
