"Failed to create CEF browser" on OSX with IntelliJ Idea maven-migrated project

[P5music]

I am using IntelliJ Idea on OSX Catilina for my project (migrated to maven).

I installed the cef folder by means of the command line instruction from the "CEF big changes" web page. The command created a /cef/cef structure.

Running the app in the simulator I got the "unable to create CEF browser" error.

I copied the files to the upper level because I believe the command created a nested cef folder. So now I have .codenameone/cef/files structure

I get

java.lang.IllegalStateException: Settings can only be passed to CEF before createClient is called the first time.

Thanks in advance

I suggest removing the whole directory then launching Codename One Settings and running the Update command from the menu on the right. It should install CEF correctly for you.

I removed the cef directory, but then it is not recreated from CN1 settings (update, save).

This issue was related to Apple's codesigning and notarization requirements, and affected only Big Sur and Catalina.  I have just published a new version 7.0.27 to Maven central which fixes the issue.  This should be generally available within the next few hours.  

Simplest way to update to the new version is to change the cn1.version and cn1.plugin.version properties in your pom.xml file to 7.0.26

Sorry... that should read version 7.0.26.  Not 7.0.27
