Gradle does not import added dependency after build operation

I am using spring-boot version 1.5.12 and gradle 5.2.1.
I have added Sentry library in my project as mentioned in its documents like below :
implementation 'io.sentry:sentry:1.7.23'
Gradle downloads the related jarFile in : \.gradle\caches\modules-2\files-2.1\io.sentry\sentry\1.7.23
and also I can see it in my IDE in External Libraries part
then I configed it in my local environment and everything worked fine and I could see my Exception reports in Sentry dashboard.
but after that when I wanted to create a version of project for my production environment, the build operation ended successfully but this new library is not in the folder(which is the result of my build operation named Distribution) which contains myPro.jar and other libraries that I use , I faced the Exception :
Exception in thread "main" java.lang.NoClassDefFoundError: io/sentry/Sentry

with jar
}
ext.distributionDir= "${rootDir}/dist/core"

jar {

}

}
task copyLibs(type: Copy){
from configurations.compile
into "$distributionDir"
}
task copyConfig(type: Copy){
from "$projectDir/src/main/resources/"
into "$distributionDir"
}
task distribution(dependsOn: ['copyLibs', 'copyConfig', 'jar']){
}
and I face Exception here :
#SpringBootApplication
#EnableMongoRepositories(basePackages = {"ir.anarestan.ipc.repository.mongodb"})
public class Boot {
public static void main(String[] args) {
SpringApplication.run(Boot.class, args);
Sentry.init();
}
}
any help would be appreciated, it has take me lots of time!!!

How to solve: Could not run build action using connection to Gradle distribution issue in eclipse?

The problem occurred, In eclipse, the project was refreshed by right-clicked project > Gradle > Refresh Gradle Project
I have tried different approaches, downloading \gradle-4.3.1 file, and by going window > preferences > local installation directory > c:\gradle-4.3.1

Kotlin+Gradle runnable jar - dependency causing "Could not find or load main class"

Gradle build file:
buildscript {
ext.kotlin_version = '1.2.41'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
group 'com.anivive'
version '0.1'
apply plugin: 'kotlin'
sourceSets {
main.java.srcDirs += 'src/main/kotlin/'
test.java.srcDirs += 'src/test/kotlin/'
}
repositories {
mavenLocal()
maven {
url "https://packagecloud.io/anivive/anivive/maven2"
}
mavenCentral()
}
dependencies {
compile 'anivive:Import_Utils:1.2.44'
compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
kotlinOptions.jvmTarget = "1.8"
}
jar {
baseName = 'XMLModelBuilder'
version = '0.1'
manifest {
attributes 'Main-Class': 'com.anivive.Main'
}
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}
File structure:
src
- main
- kotlin
- com
- anivive
- Main.kt
Main.kt:
package com.anivive
import com.anivive.util.ExampleClass
object Main {
#JvmStatic
fun main(args: Array<String>) {
ExampleClass.exampleMethod()
}
}
So, I'm trying to build a runnable jar file that will call a single method from a class in the dependency 'anivive:Import_Utils:1.2.44'.
If I remove the dependency, and change my main method to just println("Test"), the jar will run fine via java -jar build/libs/jarFile.jar and it will print out Test.
However, with the dependency included and when trying to call a function from it, I will get Error: Could not find or load main class com.anivive.Main whenever I try to run the Jar file. I suspect it has something to do with hosting the jar file on packagecloud, but I'm surprised this is a problem, considering I can run the program just fine from IntelliJ.
What gives?

Can't run generated JAR file with Gradle and Kotlin

I have a project configured with Gradle and Kotlin. It's a command line utility and I would like to be able to run the generated jar from my terminal. However I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
at com.autentia.impt.MainKt.main(Main.kt)

My gradle configuration is as follows:
buildscript {
ext.kotlin_version = '1.2.20'
ext.junit_platform_version = '1.0.1'
ext.junit_version = '5.0.0'
ext.moshi_version = '1.5.0'

}
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
kotlinOptions.jvmTarget = "1.8"
}
The command I use to generate the jar is ./gradlew clean build and the command I use to run the jar is java -jar build/libs/impt-1.0-SNAPSHOT.jar.
I've tried following the official docs and also I've tried with these resources: 1, 2 and 3 without any luck.

Just change implementation configurations to compile. (At least for kotlin-stdlib)
The compile configuration is deprecated and should be replaced by implementation or api in Gradle plugin for Android, however for kotlin-gradle-plugin, I think you still need compile.

Alright I had the same problem and finally figured this out:
My main class name was Main.kt and this is what I had in my build.gradle file when I was getting the same error:
jar {
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
manifest {
attributes(
'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
'Main-Class': "play.Main"
)
}
}
Although I noticed when I create the jar artifact in Intellij, it uses play.MainKt as my Main-Class name (yeah, weird naming convention), then I changed my build.gradle file to this:
jar {
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
manifest {
attributes(
'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
'Main-Class': "play.MainKt"
)
}
}
and now I am not getting that error.

Add Library to Gradle Kotlin app

I converted simple Kitlon file into Library, the file is:
Display.kt:
package hello
fun main(args: Array<String>) {
println("Hello World!")
}
had been compiled into library using the command:
kotlinc Display.kt -d Display.jar
The output had been cross checked to be worked using the command:
kotlin -classpath Display.jar hello.DisplayKt
Then I moved it to folder src/main/resources, then tried calling it from another app, using the below code:
Hello.kt:
package hello
import hello.DisplayKt
fun main(args: Array<String>) {
println("Hi")
}
and defined the build.gradle file as below (tried to put all option I read about to solve my case):
// set up the kotlin-gradle plugin
buildscript {
ext.kotlin_version = '1.1.2-2'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
// apply the kotlin-gradle plugin
apply plugin: "kotlin"
// add kotlin-stdlib dependencies.
repositories {
mavenCentral()
}
dependencies {
//dependencies from a remote repositor
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
//local file
compile files('src/main/resources/Display.jar')
compile fileTree(dir: 'src/main/resources', include: '*.jar')
}
jar {
manifest {
//Define mainClassName as: '[your_namespace].[your_arctifact]Kt'
attributes ('Main-Class': 'hello.HelloKt', "Implementation-Title": "Gradle",
"Implementation-Version": 1)
}
// NEW LINE HERE !!!
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}
sourceSets {
main {
java {
srcDirs = ['src/kotlin']
}
resources {
srcDirs = ['src/resources']
}
}
}
but, after running gradle build command, I got the below error:
Unresolved reference: DisplayKt
Note: I'm very very new to JAVA/KOTLIN and GRADLE

I found the answer, the full path of the function is hello.main
