问题
I am trying to run the demo program for the CodenameOne CameraKit: https://github.com/codenameone/CameraKitDemo/ after reading https://www.codenameone.com/blog/camerakit-low-level-camera-api.html It compiles and runs in the simulator, but when I send it to the server to build, it gives me a build error.
Am I missing something?
I am using the IntelliJ IDE: IntelliJ IDEA 2018.1.1 (Community Edition) Build #IC-181.4445.78, built on April 9, 2018 JRE: 1.8.0_152-release-1136-b27 x86_64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

Here follows the code, and the errors from the build server.

回答1:
It looks like you took the cn1lib and tried to use the code instead of installing the cn1lib using the extension manager available in Codename One Settings.
I would suggest installing the extension.
If you would still want to use the code notice you also need to replicate the changes to build hints which are missing. These are within the properties files that are a part of the cn1lib.
