I am trying out KTOR for building backend server application. When I try to include implementation("io.ktor:ktor-auth:1.6.8") dependency, it gives me an error
Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
class io.ktor.auth.Authentication.Feature, unresolved supertypes: io.ktor.application.ApplicationFeature
Adding -Xextended-compiler-checks argument might provide additional information.
Type mismatch: inferred type is Authentication.Feature but Plugin<TypeVariable(P), TypeVariable(B), TypeVariable(F)> was expected
Here is the error
fun Application.authentication() {
install(Authentication) { // here is the error
jwt {
}
}
}
I looked at the Authentication.kt file and it does not have any plugin in it.
how to correct this?
I took the version from mvnrepository https://mvnrepository.com/artifact/io.ktor/ktor-auth/1.6.8
EDIT. I was able to resolve it by adding different dependencies
implementation("io.ktor:ktor-server-auth-jvm:$ktor_version")
implementation("io.ktor:ktor-server-auth-jwt-jvm:$ktor_version")
If someone encounter this exception in a multiplatform project using ktor 1.4.1 and getting the client in a lazy way
private val client by lazy {
HttpClient() {
[...]
I've found, and post it here for future reference, that this is due to a known bug: https://youtrack.jetbrains.com/issue/KTOR-1087
This could happen even if you have generated your client with the openapi-generator, but fortunally the exception in this case is managed and you could call it a second time ;)
UPDATE
The issue has been fixed with target release 2.0.0
I have developed a simple JavaFX app using jgit, that is allowing users to play with git.
When the app was started from the IntelliJ idea, I was able to clone the GitHub repo using my jgit implementation of the "git clone" command without any issues. But as soon as I created an image from my app and started the app from the image, I am getting an SSL certificate issue:
Exception:org.eclipse.jgit.api.errors.TransportException:
Secure connection to https://my-github-repo.git could not be established because of SSL problems.
I am trying to understand why I am getting the SSL certificate issue only when I am running the app from the image. Can somebody explain that? I understand that I can disable SSL verification (there are some questions answered on that topic), but I want to know why it is working from IDE and not from the created image...
here is my simplified git clone implementation for http:
try {
CloneCommand command = Git.cloneRepository();
command.setCredentialsProvider(new UsernamePasswordCredentialsProvider(httpUsername, httpPassword));
// run the clone command
command.setURI(repositoryUrl);
command.setDirectory(dirFramework);
git = command.call();
} catch (Exception e) {
LOG.error("Error occurred during task: Git clone: " + e);
}
For creating the image I am using the "org.beryx.runtime" plugin with the Gradle task "runtime".
Here is the build.gradle content:
plugins {
id 'java'
id 'application'
id 'org.openjfx.javafxplugin' version '0.0.8'
id 'org.beryx.runtime' version '1.11.4'
}

}

compile 'org.controlsfx:controlsfx:11.0.2'
}
javafx {
version = "15"
modules = ['javafx.controls', 'javafx.fxml', 'javafx.web', "javafx.graphics"]
}
application {
mainClassName = 'org.sovap.taman.Launcher'
applicationName = 'taman'
}
runtime {
options = ['--strip-debug', '--compress', '2', '--no-header-files', '--no-man-pages']
imageDir = file("$buildDir/taman")
}
Edit 1:
How the image is created? - image is created with the plugin 'org.beryx.runtime' version '1.11.4', with Gradle task called 'runtime'. At the end of the build.gradle content you can see some specific configuration for runtime task.
Also, it is possible to include modules there as described here: https://badass-runtime-plugin.beryx.org/releases/latest/
I have tested the config with modules you are mentioning for runtime task in build.gradle (also one by one):
runtime {
options = ['--strip-debug', '--compress', '2', '--no-header-files', '--no-man-pages']
imageDir = file("$buildDir/taman")
modules = ['jdk.crypto.cryptoki', 'jdk.crypto.ec', 'jdk.crypto.mscapi']
}
But with that I am getting following exception when starting the app from image:

What version of Java 11 are you using? - java version "11.0.8" 2020-07-14 LTS
Regarding the different versions of JDK for image and for IntelliJ IDEA environment - it should be using the same installation on my machine
I guess I need to add modules to the runtime task, but I do not know which ones and how to identify them... Any direction you can point me to?
Edit 2:
According to the accepted answer, I was missing modules in my runtime task configuration. Here is how I have figured which ones to add:
The plugin 'org.beryx.runtime' contains a task I used for suggesting modules for the runtime task (task: suggestModules)
After running it I have created a list of modules with the following runtime config (included the ones from accepted answer):
runtime {
options = ['--strip-debug', '--compress', '2', '--no-header-files', '--no-man-pages']
imageDir = file("$buildDir/taman")
modules = [
'java.desktop',
'java.logging',
'java.xml',
'java.compiler',
'java.datatransfer',
'java.rmi',
'java.sql',
'java.naming',
'java.scripting',
'java.management',
'java.security.jgss',
'jdk.jfr',
'java.net.http',
'jdk.jsobject',
'jdk.xml.dom',
'jdk.unsupported',
'jdk.crypto.cryptoki',
'jdk.crypto.ec',
'jdk.crypto.mscapi']
}
Now everything works as expected.
The most likely situation is that you are missing a module in the JRE image related to crypto that is required to authenticate the SSL connection.
What jdk.crypto.* modules are in the final image?
Perhaps if one of these is missing it will affect the ability to handle the SSL certificates?
jdk.crypto.cryptoki
jdk.crypto.ec
jdk.crypto.mscapi
Since some aspects of the security/crypto code are done via service providers, perhaps when you generate the JRE image you should pass the
"--bind-services" option to "Link in service provider modules and their dependences"
You will need to share more details about how the image is created and what specific errors are reported. Try to include the full stack trace of any reported exceptions.
What version of Java 11 are you using?
Could you be running into this: JDK 11 SSL Error on valid certificate (working in previous versions)
(It is unlikely if you are running with the same JDK version in the IDE and the packaged image, but thought I would mention it just in case it gives you a hint.)
My code:
String token = request.getHeader("authorization"); // I was checked, token have value type Bearer.
MindsphereCredentials credentials = MindsphereCredentials.userTokenBuilder()
.authorization(token)
.build();
But my program returns an error at .authorization
ERROR get from
cf logs program_name --recent
2020-06-18T17:09:26.96+0900 [APP/PROC/WEB/0] OUT [CONTAINER] tainerBase.[Catalina].[localhost].[/].[dispatcher] SEVERE Servlet.service() for servlet [dispatcher] in context with path [] threw exception [Handler processing failed; nested exception is java.lang.NoClassDefFoundError: com/auth0/jwt/exceptions/JWTDecodeException] with root cause
I follow this link: mindsphere-sdk-java-v2/sdkreadme_v2
A NoClassDefFoundError exception usually suggests that you're missing a dependency.
This is not stated anywhere in the documentation, but it's not enough to just include the MindSphere SDK to your project alone; you also need some additional dependencies to make it work. Try adding the following to your Gradle/Maven build scripts:
org.apache.httpcomponents:httpclient:4.5.12
com.auth0:java-jwt:3.10.2
They're available in Maven Central.
Trying to run my eclipse plugin from within eclipse, I get error messages to the console, which make the nested eclipse fail to run the plugin:
org.osgi.framework.BundleException: Error starting module.
at org.eclipse.osgi.container.Module.doStart(Module.java:590)
...
Caused by: java.lang.Error: Unresolved compilation problems:

BundleContext cannot be resolved to a type

Suggesting that my plugin has compilation errors to it, but:
The plugin has not compilation errors
It seems a bit surprising that running a plugin would cause a compilation.
There was indeed no compilation error: the problem lies elsewhere. The main
Plugin class was to be a singleton, which was implemented like so:
public class Plugin extends AbstractUIPlugin implements IStartup {
public static Plugin plugin;
/ ** an empty c'tor. creates an instance of the plugin. */
public Plugin() {
plugin = this;
}
....
}
Now, other classes were referring to this public field, which not initialized; for some reason, eclipse thought this was a compilation
error. It was not. using a getter for that field solved the problem.
