Jarek Sacha commented on CONFIGURATION-714:
-------------------------------------------
You are correct that file did not exist.
I needed to save a configuration created by my code (porting from Configuration
v.1*). I was confused by the title of the section in the User Guide:
["Saving"|https://commons.apache.org/proper/commons-configuration/userguide/howto_properties.html#Saving].
I did not fully understand what is going on in the example. The example rather
than just saving a configuration, it first loads a configuration, then saves.
Since my file did not exist yet I got that exception.
You can close this issue.
Just for the record. Here is that code that worked for me when saving a new
configuration as properties:
{code:java}
// Create your configuration somewhere in the code
BaseConfiguration conf = ...
// Copy source configuration to PropertiesConfiguration
PropertiesConfiguration properties = new PropertiesConfiguration()
ConfigurationUtils.copy(conf, properties)
// Save PropertiesConfiguration
FileHandler handler = new FileHandler(properties)
handler.save(file)
{code}
> PropertiesConfiguration builder.getConfiguration fails
