I would like to get an image from JAR library to my project.

    <graphic>
        <ImageView>
            <Image url="@/toolbarButtonGraphics/general/TipOfTheDay24.gif"/>
        </ImageView>
    </graphic>

I've added the library to my module and it seemed to be correct but the compiler throws an error: Error occurred during initialization of boot layer java.lang.module.FindException: Unable to derive module descriptor for filepath.jar Caused by: java.lang.IllegalArgumentException: jlfgr.1.0: Invalid module name: '1' is not a Java identifier. Here's my module-info file:

requires javafx.fxml;
requires javafx.controls;

opens sample;

    So you have your modular app, and you add a dependency (the jar with the image)? This jar is `jlfgr.1.0.jar`? Why don't you add the jar to the module info? Have you tried renaming it to `jlfgr-1.0.jar`? – José Pereda Apr 24 '19 at 12:37
  • Adding to the module-info after renaming a file helped :) Thank you so much. –  Apr 24 '19 at 13:04

it seems like you did not follow the steps properly. When you add a new library, first, you add it to your module and then you have to add it to you module-info file.

Just add a line in module-info ---> requires <package-name>;

e.g my package name is graphics-looks.jar ---> requires graphics-looks;

P.S. before adding that jar anywhere, try to rename it and give a simple name by removing numbers and other characters from its name.

    I faced the same issue mentioned above and this solution worked for me. Having numbers and special characters in my jar file was not allowing to add in the module-info file as it is. had to rename the jar file and use. – sher17 Feb 23 '21 at 20:54

    Package name having numbers and special character made it difficult to add it to the module-info. To make it clear, what worked for me is getting rid of the numbers and the special characters. Example: renaming jlfgr-1_0 to jlfgr – Anav Katwal May 29 '21 at 14:56

Switch the project programming language, set it to version 11 on both sdk and language level. it worked for me.

According to Tarun Dadlani Answer.

Firstly, you need to add the .jar file to Modules as the pictures shown. Add .jar file to modules

Secondly, you need to add a new lib to module-info file as the pictures shown. Add a new lib to module-info file

Finally, Rename the .jar file to give a simple name.
