My project depends on a Logging library via GitHub URL (GitHub - frankleonrose/Arduino-logging-library: easy to use logging library like log4j, log4net, ...). The same Logging library is listed as a dependency (in library.json) of another dependency (Respire/library.json at master · frankleonrose/Respire · GitHub).
After running, .piolibdeps contains both
- Arduino Logging Library
- Arduino Logging Library@src-1bbdf865e74caf45af3bb1f170c67c92
It used to have both “Arduino-logging-library” and “Arduino Logging Library”. I thought adding a library.properties would fix that, but it just changed it to this new situation.
I have looked in the forum and documentation and do not see an explanation.
Why are there two copies of the library? What is making the library manager think it needs a separate copy?
Thanks.

It happened to me some rare times, had you try to delete in your project the .piolibdeps hidden folder?
Yeah, it’s very stable. If I delete .piolibdeps it just rebuilds the directory with both copies of the dependency.
I ran pio run --verbose and see that it is something about installing the same library with two names.
Installing dependencies
LibraryManager: Installing Arduino Logging Library
Arduino Logging Library @ f5d5815 is already installed
LibraryManager: Installing arduino-logging-library
Arduino Logging Library @ f5d5815 is already installed
Looking further into the code in package.py (the only place where I found the string “@src-”) I see that it is resolving package identity looking at the version string (which makes sense). Looking more closely at my platformio.ini file and the library.json file of my dependency, I noticed that the git URL’s were different.
library.json has:
"dependencies":
[{
"name": "Arduino Logging Library",
"version": "https://github.com/frankleonrose/Arduino-logging-library.git",
}],
whereas platformio.ini has
lib_deps = https://github.com/frankleonrose/Arduino-logging-library
I fixed the problem by adding “.git” to the URL in platformio.ini.
