I have a simple setup where packaging a script with a local dependency fails, because the local dependency is not included in the package. Here is the project:
$ tree ..├── libs│ └── congocc.jar└── pkgtest.kts
The script just imports a class in congocc.jar and prints it:
importorg.congocc.core.Grammarprintln(Grammar::class.java)
which runs fine when invoked like this:
$ KSCRIPT_DIRECTORY_ARTIFACTS=$PWD/libs kscript pkgtest.ktsclass org.congocc.core.Grammar
However, packaging it fails:

This is because the build.gradle.kts is missing the dependency. Here is the relevant portion of build.gradle.kts:
dependencies {
implementation(files("/home/vinay/.cache/kscript/jar_9c6421c9540b73cf0ccfbcfd1405be52/scriplet.jar"))
implementation("org.jetbrains.kotlin:kotlin-stdlib")
implementation("org.jetbrains.kotlin:kotlin-script-runtime:1.7.21")
}There's no mention of congocc.jar, even though it is contained in the relevant dependencies file:
$ cat ~/.cache/kscript/dependencies_9c6421c9540b73cf0ccfbcfd1405be52/dependencies.content /home/vinay/projects/scratch/kscript/libs/congocc.jar
Adding implementation(files("/home/vinay/projects/scratch/kscript/libs/congocc.jar")) manually to the build script and rerunning gradle makeScript solves the problem, so it's just in the construction of build.gradle.kts where the problem seems to be.
