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'
}
group 'org.sovap'
version '1.0-SNAPSHOT'
sourceCompatibility = 11
targetCompatibility = 11
repositories {
mavenCentral()
}

// xml stuff

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.
