kandi X-RAY | konfig Summary
Konfig provides an extensible, type-safe API for configuration properties gathered from multiple sources — built in resources, system properties, property files, environment variables, command-line arguments, etc. A secondary goal of Konfig is to make configuration "self explanatory”. Misconfiguration errors are reported with the location and “true name” of the badly configured property. E.g. a program may look up a key defined as Key("http.port", intType). At runtime, it will be parsed from an environment variable named HTTP_PORT. So the error message reports the name of the environment variable, so that the user can easily find and fix the error. Configuration can be inspected and listed. For example, it can be exposed by HTTP to a network management system to help site reliability engineers understand the current configuration of a running application.

QUESTION
I'm trying to query some JIRA issues using a the jira-connector package.
I'm running into issues with the data returned not being defined until after everything else is executed in my code. I'm not sure if this is some issue with concurrency, but I can't for the life of me figure out where and how I'm messing up.
If inside the getJiraTimeEstimations function only call the getJiraTimeEstimate once it works just fine and I get access to the data to use further down in the program. It is when I'm trying to do it inside a map or foreach where I iterate over the Array.from(dataFromMaconomy.keys()) array that I seem to run into issues.
My understanding is that adding .then().catch() in the getJiraTimeEstimate function should be enough to stop it from continuing to run before all the calls are finished? Or am I misunderstanding how asynchronous calls work in Node and JS?
I've also tried converting it to an async getJiraTimeEstimations and adding an await infront of the search. But it doesn't seem to work either.
I am not populating the dataFromMaconomy array as I'm debugging. Which is what I was trying to do with the log statement. The log statement just prints undefined right now. But if I only call it with a single item from the rks array then it works fine.

QUESTION
I'm packaging a shadow jar of my app. The app uses kotlin and some external dependencies. All dependencies are in my jar but i get the following exception during runtime:
java.lang.NoSuchMethodError: java.util.Optional.isEmpty()Z
The Z at the end is always there; I don't where it comes from.
I checked multiple example of build.gradle files and mine seems to be good.
...ANSWER
Answered 2020-Nov-05 at 06:07Your runtime Java Version is lower than the compile-time Java version
Optional.isEmpty() is from JDK 11+, its not in JDK 8,9
the build.gradle is fine.
just run with JDK 11

It sounds like what's happening is that the version of log4j that ends up being used isn't the version you were expecting.
Dependency version resolution can get pretty complicated, especially when you have lots of dependencies. Different things want different versions of the same dependency, but Gradle has to pick one version that will end up on the classpath. In general, it will pick the newest version from among all the versions that have been requested.
There are two reasons I can think of that upgrading Gradle might have changed the version of log4j that ends up being used:
- Something in Gradle itself could be adding a dependency on log4j, and might now be requesting a newer version than was used in the older Gradle distribution.
- On the other hand, it's possible that the way version conflicts are resolved has actually subtly changed in the newer version of Gradle.
Luckily, Gradle gives you some tools to help figure out what's going on. I would suggest comparing the output of the following command both before and after updating the Gradle version.

Install konfig
Define typed property keys val server_port = Key("server.port", intType) val server_host = Key("server.host", stringType)
Build a Configuration object that loads properties: val config = systemProperties() overriding EnvironmentVariables() overriding ConfigurationProperties.fromFile(File("/etc/myservice.properties")) overriding ConfigurationProperties.fromResource("defaults.properties")
Define some properties. For example, in defaults.properties: server.port=8080 server.host=0.0.0.0
Look up properties by key. They are returned as typed values, not strings, and so can be used directly: val server = Server(config[server_port], config[server_host]) server.start()
