Hi Jark,
You mean I shouldn't package them into the jar so I need to specify them as
compileOnly as Lake Shen pointed out? because I still need them to use it
in my IDE/compile my application. just tried it and yes it works below is
updated build.gradle
buildscript {
repositories {
jcenter() // this applies only to the Gradle 'Shadow' plugin
}
dependencies {
classpath 'com.github.jengelman.gradle.plugins:shadow:2.0.4'
}
}
plugins {
id 'java'
id 'application'
}
mainClassName = 'Test'
apply plugin: 'com.github.johnrengelman.shadow'
// artifact properties
/*group = 'org.myorg.quickstart'
version = '0.1'*/
description = """Flink Quickstart Job"""
ext {
javaVersion = '1.8'
flinkVersion = '1.10.0'
scalaBinaryVersion = '2.11'
slf4jVersion = '1.7.7'
log4jVersion = '1.2.17'
}
sourceCompatibility = javaVersion
targetCompatibility = javaVersion
tasks.withType(JavaCompile) {
options.encoding = 'UTF-8'
}
applicationDefaultJvmArgs = ["-Dlog4j.configuration=log4j.properties"]
// declare where to find the dependencies of your project
repositories {
mavenCentral()
maven { url
"https://repository.apache.org/content/repositories/snapshots/"; }
}
// NOTE: We cannot use "compileOnly" or "shadow" configurations since
then we could not run code
// in the IDE or with "gradle run". We also cannot exclude transitive
dependencies from the
// shadowJar yet (see https://github.com/johnrengelman/shadow/issues/159).

configurations {
