B4J Question (SOLVED) module b4j does not declare `uses`

[Johan Schoeman]

I am trying to compile a B4J project (Java 11) to a standalone package. It compiles fine but when running "run_debug" I get the following error. I guess it requires some PackagerProperty to be added to the B4J project? Can someone please advise what should be added to the B4J project?

C:\Users\johans\Documents\B4JApps\WebCamScanBarcode\WebCam\Objects\temp\build>cd bin

C:\Users\johans\Documents\B4JApps\WebCamScanBarcode\WebCam\Objects\temp\build\bin>java.exe @release_java_modules.txt  -m b4j/b4j.example.main
sarxoswebcam._initialize (java line: -1)
java.util.ServiceConfigurationError: org.slf4j.spi.SLF4JServiceProvider: module b4j does not declare `uses`

Is this the full error message?

Add this:

#PackagerProperty: AdditionalModuleInfoString = uses org.slf4j.spi.SLF4JServiceProvider;

Super sharp @Erel. Thanks - working 100%
