NoClassDefFoundError: org/bouncycastle/jce/provider/BouncyCastleProvider

I upgraded the plugin id 'org.springframework.boot' version '2.6.5' which led to the following changes

plugins {
    id 'java'
    id 'org.springframework.boot' version '2.6.5'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'jacoco'
    id 'org.barfuin.gradle.jacocolog' version '1.0.1'
}

bootRun {
    args = [
            '--spring.config.location=./src/configs.properties',
    ]
}

springBoot {
    mainClass = 'com.company.service.ServiceClass'
}

jar {
    // This would avoid creating an additional "-plain" jar
    enabled = true
    archiveClassifier = ''
    // Before the plugin upgrade I wasnt getting manifest attribute related error. Because of one of such errors, I added it the attribute explicitly.
    manifest {
        attributes 'Main-Class': 'com.company.service.ServiceClass'
    }
}

bootJar {
    layered {
        enabled = true
    }

When I run the jar, I get the following error

>> java -jar build/libs/service-1.0-SNAPSHOT.jar
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/bouncycastle/jce/provider/BouncyCastleProvider
    at java.lang.Class.getDeclaredMethods0(Native Method)

From the solutions I found on SO, I added the dependency

implementation group: 'org.bouncycastle', name: 'bcprov-jdk16', version: '1.46'

But this doesnt work. Plus I am still using jdk8 and there is no org.bouncycastle for jdk8. Any suggestions how I can work around this exception?

EDIT: Running the application with intelliJ doesnt throw this problem. But happens when running from command line.

EDIT:

>> % java -version

Running the application with intelliJ doesnt throw this problem. But happens when running from command line.

java -jar build/libs/my-service-class.jar

For executing a jar directly from command line, it should contain manifest information. Assuming the aforementioned jar contain the same as you're facing the the other issue(class def not found) so looks like your jar my-service-class.jar is thin jar and doesn't contain the other dependencies that you've added in the project. Two way to solve this problem. Either you can create uber jar i.e jar with all the dependencies included by using available plugins for the same and then execute the command or just add all the required dependencies into some folder and give path to it while runing the above command.
