Java Library: load file from resources-CodePudding

I'm a developing a Java library that is going to be used internally in our company. It provides a wrapper around Aerospike. When a user calls the factory method, the library should read a file from its resources.

public static IAerospikeClient newTypedClient(IAerospikeClient client) {
    LOG.info("Trying to load aerospike schema yml");

    URL resource = AerospikeTypedClientFactory.class.getClassLoader().getResource("schema.yml");
    if (resource == null) {
        throw new IllegalArgumentException("File 'schema.yml' is not found");
    }

    byte[] bytes = Files.readAllBytes(Paths.get(resource.toURI()));
    return new TypedAerospikeClient(client, new String(bytes));
}

Then I'm trying to add this library as a dependency and call newTypedClient method, I get this error.

Caused by: java.nio.file.FileSystemNotFoundException
    at com.sun.nio.zipfs.ZipFileSystemProvider.getFileSystem(ZipFileSystemProvider.java:171)
    at com.sun.nio.zipfs.ZipFileSystemProvider.getPath(ZipFileSystemProvider.java:157)
    at java.nio.file.Paths.get(Paths.java:143)
    at com.example.AerospikeTypedClientFactory.newTypedClient(AerospikeTypedClientFactory.java:30)

Is there any way to overcome this error? I guess I could add the schema.yml file to the resources folder of the library's consumer. But I definitely don't want to go into this. Because the purpose is to get rid of configurations and put them within a single artefact.

For those who interested, I wrote a custom Gradle task that generates a class with the static String field. This field value equals to the actual file content. The task runs before compileJava one. For the generation itself I use JavaPoet library. Here is the example.

task generateSchemaClass {
    def className = "Schema_"
    def directoryPath = "src/main/java/com/example/generated"
    def filePath = directoryPath   className   ".java"
    doFirst {
        TypeSpec typeSpec = TypeSpec.classBuilder("Schema_")
                .addModifiers(Modifier.PUBLIC)
                .addAnnotation(
                        AnnotationSpec.builder(SuppressWarnings.class)
                                .addMember("value", '$S', "all")
                                .build()
                )
                .addField(
                        FieldSpec.builder(String.class, "CONTENT", Modifier.PUBLIC, Modifier.STATIC, Modifier.FINAL)
                                .initializer('$S', file('src/main/resources/schema.yml').text)
                                .build()
                )
                .build()
        JavaFile javaFile = JavaFile.builder("com.example.generated", typeSpec).build()
        file(directoryPath).mkdirs()

        def output = file(filePath)
        output.createNewFile()
        output.text = javaFile.toString()
    }
}

compileJava.dependsOn(generateSchemaClass)
