How to add local jar as dependency?

[TheBoneJarmer]

Hey, today I learned about jbang and so far I think it is incredible. But one thing is preventing me from using it for real though. I am in need of using a local jar file as dependency. And this is an absolute must for me.

Using javac I could simply set the classpath. And I assume I have to do that here too somehow. But I rather use the //DEPS directive for that. I tried doing something stupidly simple as //DEPS lib/myjar.jar but it wont resolve.

EDIT:

Also perhaps good to know is that the JAR file I speak of is the result of another project of mine. But I cannot simply push that one to maven as its actually a Java wrapper for a C++ library I created. And it has to be compiled per operating system and maven does not give a damn about that. I do not like pre-compiling a dozen .so/.dll files and include them per architecture and kernel because that is a bitch to maintain.

I use JNI to communicate between Java and C++. Therefore the Java wrapper has a build script instead because it needs to compile the native library part first using CMake and than the Java part using javac. And it has to do so in a very specific order. I was however considering using jbang to build the Java part and use the //FILES directive to include the .so/.dll file in the resulting JAR. Something I now do manually in bash.

You Can use classpath to refer to jar files.

Maven does provide ways to fetch based on OS but many also just bundles All and dynamcially choose which to load.

Hey, I tried that using the //JAVAC_OPTIONS and //JAVA_OPTIONS directive but if I do that it will build but it wont run. Getting an exception because it cant find the class. Also, VSCodium keeps underlying half my code in red because it cannot resolve any of the packages and classes:

Any idea how to fix this?

the classpath I referred to was jbang's classpath option: jbang --class-path lib/app.jar ...

not sure what goes wrong in your example - try run with jbang --verbose .. then you can see what command gets executed.
