jAlbum 37.7 NPE when building from command line

Hi,

I've been using jAlbum successfully for years, building from the command line on Windows using Cygwin shell scripts to automate mass updates to my albums. However, I am now getting the following NPE from the command line using 37.7. When I revert back to 37.6 everything is fine, no NPE, etc. "Making" an album in the 37.7 gui works fine, it's only from the command line that I now get this error.

Here is the simple command line I use to build an album:

E:/JAlbum/jre64/bin/java.exe -Xmx2048M -jar E:/JAlbum/jalbum.jar -projectFile 'photo gallery.jap'


And here is the error I'm getting with 37.7:

java.lang.ExceptionInInitializerError

        at se.datadosen.jalbum.AlbumProject.getProperties(AlbumProject.java:121)

        at se.datadosen.jalbum.JAlbumFrame.<clinit>(JAlbumFrame.java:189)
        ... 9 more


For now, I'll stick with 37.6 which works for me.

Thanks!

I am getting the same error from the command line with version 37.7 and 37.7.1 on a Windows 10 PC. I have tested with albums using Turtle, Neptune, and Split skins. jAlbum software and all skins have been fully reinstalled. Reverting to version 37.6 resolves the problem.

While I agree that this error probably needs to be addressed, I would also like to comment that I used to handle the updating of multiple projects with shell script files that invoked the jAlbum command line. But I found that the multi-maker was more efficient. It allows for multi-threading, and steers clear of the "UI dependent" errors that crop up from time to time.

Link to your post warning of skin updates and multimaker as well as the command line.

Do a core update via Tools->External tools->"jAlbum core update" to have this error fixed. The splash screen should now say 37.7.2

Core update to 37.7.2 fixed it for me as well, thanks!!

BTW, my shell scripts do much, much more than just invoke jAlbum to rebuild my 200+ galleries. As an example, before they are built I verify that my .jap files have a consistent look & feel: section layouts, typography, padding around thumbnails & images, etc. The scripts can run in test mode just listing the problematic gallery properties or can update the .jap files. For some custom look&feel changes that are not controllable via gallery properties, I have custom CSS that my scripts inject into the html after it's generated by jAlbum. While I know this bit can be done in skins such as Tiger, it is much more maintainable for me to have a global custom css that I can edit in one place and it's then added to the html head sections.
