Gradle dependencies in Idea project - intellij-idea

I'm trying to use Gradle, but Idea dont see dependices. Here is my build.gradle
group 'me.ozka'
version '1.0.1'
buildscript {
ext.kotlin_version = '1.0.3'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: 'java'
apply plugin: 'kotlin'
sourceCompatibility = 1.5
repositories {
mavenCentral()
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
testCompile group: 'junit', name: 'junit', version: '4.11'
compile group: 'mysql', name: 'mysql-connector-java', version: '5.1.20'
compile 'org.eclipse.jetty:jetty-server:9.0.0.RC2'
compile 'org.eclipse.jetty:jetty-servlet:9.0.0.RC2'
}
When i'm trying import import org.eclipse.jetty.server.Server; Idea signal me an error. What i'm doing wrong?
upd: i'm also don't see jar files in Idea External library folder.
upd2: i'm add to build file apply plugin: 'jetty' and it's solve my problem!

You need to refresh your gradle dependencies.
Here are some ways of doing this.
Approach 1 (GUI):
Go to View -> Tool Windows -> Gradle
Click on the big refresh button (Refresh all gradle projects).
Approach 2 (Command):
gradle build --refresh-dependencies

How to make idea plugin in gradle generate proper project configuration for Kotlin?

I have configured my build.gradle to run gradle test and gradle run properly. However, IDEA does not show any run/test tasks after importing the configuration generated by gradle idea. It seems that these tasks are not included at ipr/iws at all.
Here is my build.gradle:
buildscript {
ext.kotlin_version = '1.2.0'
repositories {
maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.dokka:dokka-gradle-plugin:$dokka_version"
classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.2'
}
}
apply plugin: 'kotlin'
apply plugin: 'org.jetbrains.dokka'
apply plugin: 'application'
apply plugin: 'org.junit.platform.gradle.plugin'
apply plugin: 'idea'
dokka {
outputFormat = 'html'
outputDirectory = "$buildDir/javadoc"
}
sourceSets {
test.kotlin.srcDirs += 'src/test/kotlin'
}
junitPlatform {
enableStandardTestTask true
}
defaultTasks 'run'
mainClassName = 'simpledb.server.Startup'
repositories {
maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
testCompile 'org.junit.jupiter:junit-jupiter-api:5.0.2'
testRuntime (
'org.junit.jupiter:junit-jupiter-engine:5.0.2',
'org.junit.platform:junit-platform-launcher:1.0.2'
)
testCompile "org.jetbrains.kotlin:kotlin-test-junit:$kotlin_version"
}
I was wondering is there any way to make generated project configurations include these tasks(run/test)? I have also heard people saying Don't use gradle idea, so is it impossible to use gradle idea to implement this?
It is simply not necessary in your case. Just open the build.gradle file with IDEA and everything should be smooth. The idea Gradle plugin is somewhat deprecated. Not officially, but it was created by Gradle team and is not actively developed to adapt to new IDEA versions and features and so on. So if you don't need special customizations, just open the build.gradle with IDEA and you should be good to go.

How to properly configure Kotlin plugin for Gradle?

I'm trying to build a basic Gradle project. My build.gradle file is below. I keep getting the below error. I don't get it because you can find the plugin here... where I think I'm directing to: https://mvnrepository.com/artifact/org.jetbrains.kotlin/kotlin-gradle-plugin
Update: same thing happens to the spring-boot plugin if I comment out the Kotlin line. It's not just specific to the Kotlin plugin.
The error:
Error:(21, 0) Plugin [id: 'kotlin', version: '1.1.1'] was not found in any of the following sources:
- Gradle Core Plugins (not a core plugin, please see https://docs.gradle.org/3.3/userguide/standard_plugins.html for available core plugins)
- Gradle Central Plugin Repository (no 'kotlin' plugin available - see https://plugins.gradle.org for available plugins)
Build.gradle:
buildscript {
ext.kotlin_version = '1.1.1'
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.6.RELEASE")
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
plugins {
id 'java'
id 'kotlin' version "1.1.1"
id 'spring-boot'
}
group 'si.dime.kotlin.tutorials.rest'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
compile("org.springframework.boot:spring-boot-starter-web:1.3.3.RELEASE")
}
For non-core Gradle plugins (those that are not from the org.gradle namespace), you have to use a fully qualified id as well as a version number.
The official Kotlin documentation contains the id to use:
plugins {
id "org.jetbrains.kotlin.jvm" version "<version to use>"
}
(You can also find these ids by searching for the plugin on the plugins.gradle.org site.)

IntelliJ Idea 16 CE gradle issues

In my gradle file I am trying to use the following to solve another issue. This is my gradle file:
group 'com.winapp'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'src/main/java/libs', include: ['*.jar'])
compile 'com.intellij:forms_rt:6.0.5'
testCompile group: 'junit', name: 'junit', version: '4.11'
}
task copyDependenciesToTarget(type: Copy) {
println 'Copying dependencies to target...'
configurations.compile.collect().each { compileDependency ->
copy {
with from (compileDependency.getPath()) {
include '*'
}
into 'target/libs/libs'
}
}
}
build.dependsOn(copyDependenciesToTarget)
jar {
manifest.attributes(
"Main-Class": "Main",
"Class-Path": configurations.compile.collect { 'libs/' + it.getName()}.join(' ')
)
}
The problem are is this:
configurations.compile.collect().each { compileDependency ->
copy {
with from (compileDependency.getPath()) {
include '*'
}
into 'target/libs/libs'
}
}
When I run the application I get this Exception:
org.gradle.api.internal.file.copy.CopySpecWrapper_Decorated cannot be cast to org.gradle.api.internal.file.copy.CopySpecInternal
Main problem is, I have no idea how to fix this error, I simply want my project to create a JAR file that works with JDBC, using this gradle code seems to be a solution for that issue, but now I have run into another problem, yet again.
Please let me know if you require any additional information and thank you in advance. Literally, I cant even. This problem.
EDIT
As stated in the comments. My project runs fine when I run it through the IDE. There is an issue when I create a JAR file using gradle. The bare gradle file that IntelliJ created when I started the gradle project follows (Added the jar config so my Main class would be picked up):
group 'com.winapp'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'src/main/java/libs', include: ['*.jar'])
compile 'com.intellij:forms_rt:6.0.5'
testCompile group: 'junit', name: 'junit', version: '4.11'
}
jar {
manifest.attributes(
"Main-Class": "Main",
"Class-Path": configurations.compile.collect { 'libs/' + it.getName()}.join(' ')
)
}
When I execute my app from terminal after the JAR has been created (keeping in mind there are no issues when hitting run in the IDE) with java -jar myAppName.jar:
java.lang.ClassNotFoundException: org.sqlite.JDBC
NOTE: Usually I get a full stack running a java app, but in this case the above is the only output.
I am using this JAR for my sqlite needs:
sqlite-jdbc-3.15.1
As a test I commented out the Sqlite usage in my application and the JAR file worked fine. My GUI was displayed and everything went as expected (all things considered). The JAR stops working when I add the sqlite JAR file usage (code). Added it the same as my other libs (like retrofit), so this seems to be quite a strange issue.
Please let me know if I have explained the issue correctly?

IDEA showing a project twice in tree

I have a Kotlin project with Gradle that has two children. Whenever I try to open it in IDEA, one of the children is shown twice in the tree.
In the tree, you can see two projects at top level, grpc and grp. The issue is that grpc (from top level) is the same project as the grpc that's a children of grp.
Here are my Gradle build files:
The parent gradle.build:
buildscript {
ext.kotlin_version = '1.0.1'
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
}
}
The gradle.settings file:
include ':grpstd', ':grpc'
The grpc gradle.build:
apply plugin: 'antlr'
apply plugin: 'application'
apply plugin: 'kotlin'
mainClassName = 'sron.grpc.MainKt'
compileKotlin.dependsOn generateGrammarSource
generateGrammarSource {
arguments += ['-package', 'sron.grpc.compiler.internal']
}
dependencies {
antlr 'org.antlr:antlr4:4.5.2-1'
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
compile 'commons-cli:commons-cli:1.3.1'
compile 'org.ow2.asm:asm:5.0.4'
compile project(':grpstd')
testCompile 'junit:junit:4.12'
testCompile "org.jetbrains.kotlin:kotlin-test:$kotlin_version"
}
The grpstd gradle.build:
apply plugin: 'kotlin'
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
testCompile 'junit:junit:4.12'
testCompile "org.jetbrains.kotlin:kotlin-test:$kotlin_version"
}
Why is that project being shown twice? How can I prevent it?
Open your project structure dialog (you can use Ctrl+Alt+Shift+S), turn to the Modules section, check if you have duplicated module defined there.
If there is, remove the unnecessary ones.
You may want to try disabling the Create separate module per source set option when importing the Gradle module.
So, the full steps are:
Open Modules
Remove the gradle module
Re-import the module. On the second page of the import wizard make sure you disable the option: Create separate module per source set

Intellij-idea gradle sub-module keeps forgetting root project dependency

I have two gradle projects defined like so
apiclient (root)
| src\
| build.gradle
|--- android (module)
| src\
| build.gradle
These projects are not on maven, yet, and the module apiclient.android depends on the root module (apiclient).
I keep adding apiclient using the project structure... -> dependency dialog and the reference keeps getting removed from the .iml file whenever I click refresh in the gradle tool window.
how can I keep the child module from forgetting the parent module dependency?
edit: as requested the build.gradle files.
apiclient build.gradle
group 'emby.apiclient'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.7
repositories {
mavenCentral()
}
dependencies {
compile 'org.codehaus.groovy:groovy-all:2.3.11'
testCompile group: 'junit', name: 'junit', version: '4.11'
compile 'com.google.guava:guava:18.0'
compile 'org.java-websocket:Java-WebSocket:1.3.0'
}
apiclient.android build.gradle
group 'emby.apiclient'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.7
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'org.codehaus.groovy:groovy-all:2.3.11'
testCompile group: 'junit', name: 'junit', version: '4.11'
compile 'com.google.code.gson:gson:2.5'
compile 'com.mcxiaoke.volley:library:1.0.16'
compile 'com.squareup.okhttp:okhttp:2.1.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.1.0'
compile 'emby.apiclient:apiclient:1.0-SNAPSHOT'
}
The last line compile 'emby.apiclient:apiclient:1.0-SNAPSHOT' is underlined red in the gradle project window. I've tried compile project 'apiclient' as well and the outcome is unchanged.
settings.gradle
rootProject.name = 'apiclient'
include 'android'
findProject(':android')?.name = 'emby.apiclient.android'
In the /android build.gradle file, you need to add compile project(":apiclient") to your dependency list. I found out the hard way that IntelliJ's "Do you want to add a dependency to classpath" dialog only adds it to the .iml file, which isn't run as part of the build.
