As far as I know SLC (by design) expects the same project structure as Eclipse so if it is not compiling I can't help. However I see you are using Java 11. SLC, or strictly BADoclet, does NOT like Java 11 and will error or, worse, produce malformed XML files. This is a long standing problem that Erel needs to sort out some time soon but for now you need to use Java 8. SLC uses the the same Java as B4A so you change it there in Tools -> Configure Paths and close the IDE before using SLC.
