Java error when installing

[Flurrywinde]

I d/led the 2.0 release, then executed java -jar image-manager-2.0.0-SNAPSHOT.jar as the Releases page says. I got the following error:

Error: Could not find or load main class nl.juraji.imagemanager.Main
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

My system info:

OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4)
OpenJDK Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4, mixed mode)

Hey @Flurrywinde,

That error means your Java environment (OpenJDK in your case) does not have the JavaFX plugin.
You need the Java JRE, on your Ubuntu system it's running $ sudo apt install default-jre from within your terminal. Check out this website, it has a step by step guide.

Note you can install the JRE alongside the your currently installed JDK.
I'll add a task to implement a fallback for systems without the JavaFX plugin.

Let us know if the solution worked!

Hi, thanks for the help. sudo apt install default-jre by itself didn't work, so I installed openjfx as well, still no luck. Then I did sudo update-alternatives --config java and selected Java 8 instead of 11. Now it worked! Thanks again... except, now I'm actually trying to backup my images, and it's not working. Let me know if I should open new issues for each problem, but I figure maybe someone else with my system might have all the same issues too.

I was able to enter my login info and login. My two boards showed up in the list, but when I indexed them, it still said zero images afterwards. I did System->View Logs, but it froze. kill didn't work, so I did a kill -9. I opened it again and tried to Open in Pinterest one of the boards. It froze up again, and I had to kill -9 again.

EDIT: I think maybe I was not able to actually log in. I have one secret board that didn't show up, and I believe, when accessing Pinterest via a browser, I am logging in via Google, not the username and password I put in in the Settings (which I guessed at and thought was successful). Will Image Manager 2 work if I log in that way and don't seem to have an actual Pinterest-only password?

Yes, I'd like new issues for new problems.

In response to your questions:

1. I've had more people stating Image Manager freezes on Ubuntu systems. Personally I've only used Image Manager on Windows and MacOSX. I have an Ubuntu 18.04 system, I shall be looking into it tonight.
   As for the update-alternative fix and Java 11 to 8, I will put that in the README, so other people know.
2. I'm not sure how Pinterest does the Google login. Maybe I should have the user login via a browser window into Pinterest and persist the access token. But seeing as you were able to find boards, Image Manager was able to access your account. The not indexing issue could be caused by an issue fixed in the stable release, see Boards with sections do not complete indexing #1 . Have you tried the latest release? You can simple replace the old JAR file with the new one, migration is automated. :D

I will create issues for these two.

If anyone else is running on Linux Ubuntu and having the Could not find or load main class-error.
Follow the steps on the Installation Guide in order to install the correct Java version.

I will close this issue since the initial issue is now resolved
