CameraKitDemo3\lib\impl\native\javase\com\codename1\camerakit\impl\CameraNativeAccessImpl.java:5: error: package com.github.sarxos.webcam does not exist
import com.github.sarxos.webcam.Webcam;

I could not find this in the extensions manager.

You'll need to refresh libs, then do a clean build. That is part of the cn1lib.

The refresh is where I first saw the message. This is the Third empty project I pasted the code in to. The extension is up to date. Below is the code from the refresh.

It's possible your build.xml file is out of date. Compare your build.xml file with this one. In particular, look in the -post-jar target. Classpath should be classpath="${run.classpath}:${build.classes.dir}:lib/impl/native/javase">

Thomas McNeill · Answer 4 · Wed Apr 17 2019 00:42:13 GMT+0800 (China Standard Time)

That got me further. The refresh works but the build fails. Attached is from the build server.

What went wrong:
A problem occurred evaluating root project 'CameraKitDemo3'.

Could not find method implementation() for arguments [co.infinum:goldeneye:1.1.2] on root project 'CameraKitDemo3'.

I have the same issue.
Steps to reproduce: create a new bare bones project, add the CameraKit cn1lib, try to refresh cn1libs... and you will see the error. Refreshing again or trying to compile don't solve the issue.

Adding the line <pathelement path="lib/impl/native/javase"/> allows the project to compile, however this seems an issue of the updated version of the build.xml provided by Codename One:

[...]
<target name="-post-jar">
        <mkdir dir="native/javase" />
        <mkdir dir="native/internal_tmp" />
        <mkdir dir="lib/impl/native/javase" />
        <path id="native.jars.class.path">
            <pathelement path="${run.classpath}"/>
             <pathelement path="${build.classes.dir}"/>
        <pathelement path="lib/impl/native/javase"/>
    
           [...]
