I pulled an example from GitHub [GitHub - inductiveautomation/ignition-sdk-examples: Ignition SDK Example Projects](https://github.com/inductiveautomation/ignition-sdk-examples) Using IntelliJ IDEA for compilation, an error was reported when executing the package: Cannon invoke "java. til.List. terator()" because the return value of "org. Apache. Maven. project. MavenProject. getCollectedProjects()" is null  
I haven't found where the problem lies, or has anyone encountered this problem before
