Hello, I have a project which requires the JNA libraries on runtime. I included compile group: ‘net.java.dev.jna’, name: ‘jna-platform’, version: ‘4.2.2’ in my gradle.build file and everything compiles fine. However, when I open the jar I get a NoClassDeffounderror error because the JNA library is…

Fortunately I have solved my issue without the usage of external plugins. Here is the fixed code which t…

You might be interested in using the Shadow plugin . It generates a “fat-jar”, which is a Jar with the necessary dependencies. Note that the plugin creates a new task shadowJar to generate the “fat-jar”. Hope this helps :slight_smile:

Hey thank you that worked. Howevever, I am very surprised gradle offers no native functionality for this. I thought managing dependencies was the entire purpose of gradle. Very confusing. Anyone knows why this is?

First of all, the default jar that Gradle produces will only contain the classes compiled from the source code in the project. It would be counterproductive to always include all of the dependencies in that jar because depending on the deployment environment, those dependencies would already be prov…

This is very interesting, but in my case I can only compile the code if I add the lib to both compile and extraLibs, any idea?

@David_Karr , your information makes sense. However, when everything runs fine during compilation (and run), but gradle cannot find dependencies during jar packaging (none of them found), then the process of building a jar file so as to make a library project available as a traditional jar library, b…

Thank you so much for actually revisiting the question. Helped me much.

Perhaps because you use another Gradle version ? I am not sure though. Btw, this thread has accumulated over 25.000 views, that’s amazing!

You are my hero - you saved my day!
