Question

My byild.gradle file

Able to export jar with JAVA 8. when I configure to JAVA 11 exported jar doesn't contain external jars

// Apply the java-library plugin to add support for Java Library apply plugin: 'java-library'

// In this section you declare where to find the dependencies of your project
repositories {
    jcenter()
}

configurations 
    { 
        all*.exclude group: 'org.slf4j', module: 'slf4j-log4j12' //by both name and group
    }

dependencies {
    // This dependency is exported to consumers, that is to say found on their compile classpath.
    api 'org.apache.commons:commons-math3:3.6.1'

    // This dependency is used internally, and not exposed to consumers on their own compile classpath.
    implementation 'com.google.guava:guava:21.0'

    // Use JUnit test framework
    testImplementation 'junit:junit:4.12'

add this below lines into your build.gradle

jar { manifest {attributes "Main-Class": "your main class" } from {configurations.compile.collect { it.isDirectory()? it : zipTree(it) } }

then do a clean/build, the jar created in \\build\\libs folder is your runnable jar
