Mobile Atlas Creator / Bugs / #344 Failed to load map packs: Failed to enumerate installable mappacks

r_x - 2020-10-03

You don't provide much information which makes it difficult to help you.
Is this a fresh installation of MOBAC?
Wher have you installed MOBAC to (complete path)?
Make sure the path is within your home directory or another path where you have always full write permissions (without root).

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Hello. I had tried again to run the program, and then:

I have a MacBook Pro with the OS of Catalina (10.15.7). I have my file in my desktop. But i do not know what is the problem. Thanks for your attention.

On MacOS the desktop is as far as I know a protected folder (MacOS privacy protection). If you have run a different Java based application before and denied access to the desktop this is also effective for MOBAC as it uses the Java Runtime, too.

Therefore check your MacOS Security / privacy settings is Java Runtime is allowed to access the Desktop folder.

Good afternoon.

I had changed these preferences and now, altough it's supposed that Java can acces to my desktop, it's imposible to run the program.

  What do you mean by "impossible to run?"
  
  I improved the error message to better understand what is going wrong. Please check the "test4" version of the experimental 2.20 version:
  
  https://sourceforge.net/projects/mobac/files/Alpha%20and%20experimental/

I have exact same error and also tried the test4 version. I think it has somethign to do with mac security not allowing the map files. Any work arounds? cant get it run at all. After it fails I need to restart to get it to even attempt to run again. Installed latest jave and running OSX 11.0.1 ???

I don't think it has something to do with the map files itself. The error indicates that the file list in the mapsources subdirectory of MOBAC fails.
MOBAC tests that the directory exists and afterwards it tries to get the file list of that directory and that fails. The directory listing is not just empty it totally fails.

Is there an earlier version of java or mobcap that I could try?

r_x - 2021-03-18

From my perspective this is a permission problem of MacOS and Java. MOBAC has no influence on this problem. You have to allow Java to access the folder MOBAC has been installed to. This has to be done manually by the user in the security settings of MacOS.

To See the exact path of the folder MOBAC needs to access please check out the latest unstable version: https://sourceforge.net/projects/mobac/files/Alpha%20and%20experimental/

It should show the real error message as provided by the OS.

  I’m sorry but I’m not a coder and can barely understand all this…I’m just
  someone who is trying to use cartograph pro on iOS and wants additional
  maps.
  
  Your link below went to 2 zi downloads. I downloaded both TO THE DESKTOP
  and double clicked on “Mobile_Atlas_Creator.jar” to launch.
  
  I got the same error screen shown here with this error cut and pasted:

  Can you please explain what I am looking for in this and what exactly to
  do? Is the problem associated with them being on the desktop? Should I
  put them in a folder before launching?

    This has nothing to do with coding this is a security function of the MacOS system which you should know as a MacOS user.
    You need to grant Java access to the Desktop folder respectively the MOBAC folder on the desktop see:

      Ok now this makes sense. I went in there and java is not listed in “files
      and folders” and the “+ -“ plus and minus buttons are greyed out. How do I
      add java? I can’t even find java in applications????….it seems to be
      installed somewhere??? I tried uninstalling it for the java site
      uninstaller once then reinstalled.
      
      How do I add it to that list and then all the OS to allow desktop access?
      
      …or could I just move the folder somewhere else???

  According to this blog post the following folders are protected on Catalina:
  
  ~/Desktop,
  
  ~/Documents,
  
  ~/Downloads,
  
  iCloud Drive,
  
  third-party cloud storage, if used,
  
  removable volumes,
  
  network volumes.
  
  Considering this list an external drive is not a good idea.
