Quickest way possible to test Pi4J

[mhixson]

Hi, I would like to compile a single .java file to verify that Pi4J is going to work for me. The install script installs SDKMan, Maven, Gradle, and probably some other stuff, and then reboots my Pi without asking. Then running maven to download dependencies for the "minimalist" example downloads 156 .jar files!

Is there a single .jar file I can grab and do something as dead simple as:

javac -cp Pi4j.jar MyTestClass.java

Is this possible?

Thanks.

Hi @mhixson, I use JBang for such small tests. That's a quick installation...
A lot of example files are available on https://github.com/Pi4J/pi4j-jbang

# Install JBang
$ curl -Ls https://sh.jbang.dev | bash -s - app setup

# Check JBang by requesting its version
$ jbang --version        
0.109.0

# Execute a file without downloading the GitHub repo
$ jbang https://github.com/Pi4J/pi4j-jbang/blob/main/digital/ButtonLed.java
