Scala jar read external properties file

Question

I have written some code and exported it as a jar file. In this jar there is a file named automation.properties with defaults that I'm loading using

val automationPropertiesFileURL = getClass.getResource("/automation.properties")  
  if (automationPropertiesFileURL != null) {
    val source = Source.fromURL(automationPropertiesFileURL)
    config = new Properties()
    config.load(source.bufferedReader())
  }

But when this jar file gets added as a gradle dependency in C:\User\abc\.gradle and I want to read automation.properties from my current project, how can I override the location and read the file from my project and not from the jar file itself?

Answer 1

The class loader will load the file from the location it finds first.

In your case, the file exists in two places:

• Inside the current project itself
• Inside a jar dependency

Which file will be found by the class loader, depends on the ordering of the "current project" and the jar dependency on the classpath. That's what you need to review, that's the key to loading the right file.

Your current code is correct as it is, this is a matter of classpath configuration.
