I am using eclipse for a coding course at school, and I am required to install Violet UML Editor http://alexdp.free.fr/violetumleditor/page.php to create PDF of classes.
Anyway, I downloaded a .jar file. My mac doesn't like that it's from an unverified developer so I must manually allow it to open in system preferences. The .jar opens to the loading tab but it wont open the program.
'''Javac -version''' in terminal says javac 16.02. As far as I know, JDK holds JRE which I need to run Violet. To be safe I installed JRE from Oracle which was a JDK 8 file but it didn't work so I just deleted it.
UPDATE: Using terminal and entering '''java -jar violetumleditor-3.0.0.jar''' I get the error code
Error: Unable to access jarfile violetumleditor-3.0.0.jar
the .jar is located on my desktop, it should be found
Also yes I did a fresh 3.0 version install to try and the same thing.
UPDATE 2:
java -version gives
java version "16.0.2" 2021-07-20
Java(TM) SE Runtime Environment (build 16.0.2+7-67)
Java HotSpot(TM) 64-Bit Server VM (build 16.0.2+7-67, mixed mode, sharing)
Thinking it's a permission with accessing desktop issue.
There is a bug open for this: https://sourceforge.net/p/violet/bugs/69/ I personally don't think it would be fixed anytime soon. I can recommend two alternative tools such as: https://www.visual-paradigm.com/solution/uml/uml-tool-for-mac/ https://gitmind.com
