I have created a custom library for local usage. I call is ABC_node for ESP32 and the structure is as follows:

.
|-- examples
|   |-- bnoCalibStorage
|   |   `-- bnoCalibStorage.ino
|   |-- influxHTTP_write
|   |   `-- influxHTTP_write.ino
|   |-- influxPing
|   |   `-- influxPing.ino
|   |-- influxUDP_write
|   |   `-- influxUDP_write.ino
|   `-- rtcTimestamp
|       `-- rtcTimestamp.ino
|-- keywords.txt
|-- library.properties
|-- README.md
|-- ABC_Node.cpp
`-- ABC_Node.h

I tried following the Adafruit GitHub Repository structure where each example is placed inside a folder named after the sketch.

I am hosting this repository on a private GitLab Server. I used git tag v1.0.0 to create a tag and from GitLab I could download the .zip file for the stable v1.0.0 library.

I manually extracted the files to my <user>\Documents\Arduino\libraries folder and renamed the folder to ABC_Node (since my gitlab repo is named something else)

I restarted my IDE but I could not find the library ABC_Node in

Sketch\Include Library\

library.properties

name=ABC_Node
version=1.0.0
author=Shan Desai
maintainer=Shan Desai
sentence=Firmware to create InfluxDB measurements and send them via HTTP/UDP to Core
paragraph=ABC_Node provides `String` based InfluxDB measurements which can then be sent via HTTP/UDP to a central InfluxDB instance.
category=Data Processing, DAQ
architecture=ESP32
repository=https://[gitlab-address]/node-repo.git

I followed the Libraries Guide from Arduino on local Installation

System

Windows 10

Arduino IDE 1.8.5

Your library.properties is lacking a line. Emulating your library with blank files and copying in your library.properties content, and running on Linux from the command line, it reports to me:

Invalid library found in /home/matt/Arduino/libraries/ABC_Node: Missing 'url' from library

So you lack the line:

url=https://whatever.website.you.want.to/point.to

(Or use something like http://example.com if you don't want one...)

I put that line in, and magically the library appears in the list.

  • Can you tell me what commandline you used here ?

  • You just run the Arduino program. No need for any options or anything.

  • so just execute it from the IDE?

    Pardon? Execute what from the IDE? On Linux at a BASH terminal prompt I typed, precisely, /home/matt/Downloads/arduino-1.8.5/arduino and it gave me that error on the screen as the IDE loaded. I doubt you can do the same on Windows though...

  • That was what I was expecting as an answer. The commandline tool arduino. You are right it I am not sure if I can execute arduino on CMD or Powershell. Thanks.
