LDF downloads always all "lib" dependencies regardless of lib_deps

[BlueAndi]

Configuration

Operating system:
Win10 + VSCode + PIO

PlatformIO Version (platformio --version):
6.1.11

Description of problem

The platformio.ini contains several environments. Every environment requires a different set of libraries, which are configured by lib_deps. The problem is that ALL dependencies are downloaded for every environment, means .pio/libdeps/<ENV> contains always all of them.

Steps to Reproduce

platformio.ini

[env:testA]
board = esp32doit-devkit-v1
board_build.filesystem = littlefs
platform = espressif32 @ ~6.5.0
framework = arduino
lib_deps =
    A

[env:testB]
board = esp32doit-devkit-v1
board_build.filesystem = littlefs
platform = espressif32 @ ~6.5.0
framework = arduino
lib_deps =
    B

lib/A/library.json

{
    "name": "A",
    "dependencies": [{
        "owner": "makuna",
        "name": "NeoPixelBus",
        "version": "~2.7.3"
    }]
}

lib/B/library.json

{
    "name": "B",
    "dependencies": [{
        "owner": "bodmer",
        "name": "TFT_eSPI",
        "version": "~2.5.31"
    }]
}

Actual Results

.pio/libdeps/testA/ folder contains NeoPixelBus and TFT_eSPI libraries
.pio/libdeps/testB/ folder contains NeoPixelBus and TFT_eSPI libraries

Expected Results

.pio/libdeps/testA/ folder contains ONLY NeoPixelBus library
.pio/libdeps/testB/ folder contains ONLY TFT_eSPI library

Notes

It seems LDF loops over every library in ./lib instead of following environment wise.

Do you run only the specified environment? pio run -e testB

[BlueAndi]

The environments are exclusively used, depended on the use case. Not sure whether I understood your question right. :-)

Please provide a simple project (as ZIP attached to this issue) to reproduce this issue.

I can't reproduce this issue:

$ pio run  -e testA

I believe you did reproduce the issue. lib/A/library.json contains ONLY NeoPixelBus as a dependency, however in the libdeps folder you have TFT_eSPI too. This is what the issue describes on the first comment.

[ivankravets]

Does NeoPixelBus depend on TFT_eSPI?

[gabryelreyes]

No, it does not.

Thanks, we reproduced this issue. This is a normal behaviour, see https://github.com/platformio/platformio-core/blob/develop/platformio/package/commands/install.py#L258

We resolve dependencies BEFORE LDF starts (because we need all manifests). Please note that libraries installed/copied to the libdeps folder are not always built (LDF decides). Also, external libraries from the registry are cached locally, there is not "redownloading" that could lead to additional compilation time.
