I use typesafe config and try to override some properties in application.conf from jar.

I have application.conf inside my jar:

title: "test-inside" 
sub-title: "sub-test-inside"

and application-test.conf outside my jar:

include "application"
title: "test-outside"

I try to use both parameters inside my program.

I launch my jar with the next command:

java -Dconfig.file=application-test.conf -jar scala-spark-maven-1.0-SNAPSHOT-jar-with-dependencies.jar

But I get the error:

Exception in thread "main" com.typesafe.config.ConfigException$Missing: merge of system properties,application-test.conf: 1: No configuration setting found for key 'sub-title'

typesafe config doesn't use properties from inside application.conf file.

CodePudding user response：

The problem was that I have to set ".\" before external application.conf file name.

java -Dconfig.file=.\application-test.conf -jar scala-spark-maven-1.0-SNAPSHOT-jar-with-dependencies.jar
