I'm afraid that didn't quite work (no change in behavior).
Did I correctly understand you to mean this?
@Inject
@Config(value = { "trellis.configFile", "TRELLIS_CONFIG_FILE" })
private Optional<File> configFile;
I've also tried it with required=false:
@Inject
@Config(value = { "trellis.configFile", "TRELLIS_CONFIG_FILE" }, required =
false)
private Optional<File> configFile;
with the same behavior...
