Hello, I want to package a folder containing some json files together with my service module. The folder lives in the same directory as the module (I don't want to have it in the module because there is other services that use it too). I tried creating a source set in the build script for the module to include it as a resource for main as follows:

sourceSets {
    main {
        resources {
            setSrcDirs(listOf("src/main/resources", "../external-resources/json-folder/"))
        }
    }
}

This solves my problem when I run

./gradlew build

locally, the files from that folder are all available in

/build/resources/

for the module. However, when I run the jar like this:

java -jar build/libs/my-service-0.0.1.jar

I get a NullPointerException when trying to fetch one of the json files form resources. I get the resource like this from inside the module:

javaClass.classLoader.getResource("./json-file.json")

Am I doing something wrong? Why is that file fetchable when building the jar and running unit tests that call the code to fetch that file but when running the jar I get the NullPointerException? Any help would be appreciated, thanks!

You can just do

srcDir("../external-resources/json-folder/")

to add that resource dir, instead of

setSrcDirs

and listing all, but that is not influencing your problem.

managed to solve it by removing the "./" when getting the resource

Oh, yeah, of course, could have seen that. 😄

interesting, I never knew that
