I've multiple modules in my gradle project. I want all the source code jars and dependencies jars to be in lib folder and it should be zipped to upload on repository. I've written the code as per my (a newbie's) understanding but I'm not sure why isn't it working.
myProject's build.gradle
apply plugin: 'idea'
apply plugin: 'distribution'
apply plugin: 'groovy'
apply plugin: 'java'
apply plugin: 'maven'
tasks.register("projectDistribution", Zip) {
group = 'build'
dependsOn jar
archiveName = 'myProject.zip'
duplicatesStrategy 'exclude'
project.getTasksByName('distZip', true).each{task ->
dependsOn task
task.enabled = false
task.archiveName = task.project.name
with task
}
from (jar){
into 'myProject/lib'
}
from(sourceSets.main.runtimeClasspath.files.findAll {it.name.endsWith('jar') }.collect { it }) {
into 'myProject/lib'
}
from(sourceSets.main.runtimeClasspath.files.findAll {it.name.endsWith('jar') }.collect { zipTree(it) })
{
into 'myProject/lib'
}
buildscript{
repositories {
maven {
url uri('http://myRepoUrl')
}
}
dependencies {
classpath 'io.spring.grale:dependency-management-plugin:1.0.7.RELEASE'
}
}
This is my module's gradle.build file
buildscript{
repositories {
maven {
url uri('http://myRepoUrl')
}
}
dependencies {
classpath 'com.google.guava:guava:27.1-jre'
}
}
plugin{
id 'java'
}
repositories{
mavenCentral()
}
dependencies {
compile project(":myModule2")
compile 'com.google.guava:guava:27.1-jre'
}
task distZip(type: Zip, dependsOn: [ jar ]) {
baseName = 'myProject'
duplicatesStrategy 'exclude'
from (jar){
into 'myProject/lib'
}
from(sourceSets.main.runtimeClasspath.files.findAll {it.name.endsWith('jar') }.collect { it }) {
into 'myProject/lib'
}
}
According to me, this code should create a distributions folder in build which should have a zip file with all the jars. But I do not see the distribution folder itself. Can you please guide me understand my mistake.
Any suggestions on this would be highly appreciated!

I just made an update from spring boot version "2.2.1.RELEASE" to 2.5.6 and along with that I also updated the gradle version to 7.0. Before the update everything worked fine but after the update it seems that the bootRun task doesn't find the main class.
This is the error received:
Deprecated Gradle features were used in this build, making it
incompatible with Gradle 8.0. Use '--warning-mode all' to show the
individual deprecation warnings. See

I tried both ways, from command line and from ide (IntelliJ)
clean bootRun -Dspring.profiles.active="some-profile"
I found the solution and the issue has been inside the task pathingJar.
Before:
task pathingJar(type: Jar) {
dependsOn configurations.developmentOnly
archiveAppendix = 'pathing'
doFirst {
manifest {
attributes "Class-Path": configurations.developmentOnly.files.collect {
it.toURI().toString().replaceFirst(/file:\/+/, '/')
}.join(' ')
}
}
}
After:
task pathingJar(type: Jar) {
dependsOn configurations.runtimeClasspath
archiveAppendix = 'pathing'
doFirst {
manifest {
attributes "Class-Path": configurations.runtimeClasspath.files.collect {
it.toURI().toString().replaceFirst(/file:\/+/, '/')
}.join(' ')
}
}
}
So the solution has been to change the following two lines of code
dependsOn configurations.developmentOnly -> dependsOn configurations.runtimeClasspath
attributes "Class-Path": configurations.developmentOnly.files.collect {...} -> attributes "Class-Path": configurations.runtimeClasspath.files.collect {...}
Long story short is that somehow another tasks interfered with this task on developmentOnly scope and I had to change it to runtimeClasspah
Edit:
Another issue might be inside of bootRun task. You can define the package where is the main class.
bootRun {
main = 'edu.somepacke.MyMainClass'
dependsOn pathingJar
doFirst {
classpath = files(sourceSets.main.output.files, pathingJar.archiveFile)
}
//extra logic
}
I am getting an error "File can't be indexed twice" in gradle build for sonar. Do i have to add any inclusion/exclusion property for sonar? Any help greatly appreciated.
If I take out "src/main/java" in test under sourceSets, I am getting compilation error for junit test cases.

The issue described is most likely caused by custom tasks for what Gradle offers out of the box:
Task preclean deletes probably too much. Use clean instead.
Task jcompile compiles the main Java sources which basically duplicates compileJava. The jar task, by default, already depends on compileJava.
I suggest the following:
Remove sourceSets configuration since you're following the convention of using src/main/java and src/test/java.
Remove custom tasks preclean and jcompile.
Cleanup your build script and remove empty tasks copyClasses and copyResources as well as no-op assignment version=version.
From there on, should you have requirements to customize the build, try to resort to what Gradle offers already. You may want to read Building Java & JVM projects first.
I want to create a sample dependency from project in gradle to project to maven
apply plugin: "maven-publish"
apply plugin: "java"
repositories {
mavenLocal()
}
sourceSets {
main {
java {
srcDirs 'java'
}
resources {
srcDirs 'build'
}
}
}
task sourcesJar(type: Jar) {
from 'build/libs'
classifier = 'sources'
}
publishing {
publications {
maven(MavenPublication) {
groupId = 'or.gradle.sample'
artifactId = 'sort-array'
version = '1.1'
artifact sourcesJar
}
}
repositories {
mavenLocal()
}
}
but when I type:
gradle publishToMavenLocal
I have in log :
... Publishing to repository null ....
and BUILD FAIL
I cannot seem to access main classes within the test package in my Kotlin module within an Android Studio project. Please note that all code shown below is within a Kotlin JVM module that is imported into the Android app.
Here's my src/main/java code:
import com.google.gson.annotations.SerializedName
data class Customer(val password1: String,
val password2: String,
#SerializedName("last_name") val lastName: String,
#SerializedName("first_name") val firstName: String,
val email: String)
My test code in src/test/java:
class CreateUser {
#Test
fun createRandomUser() {
val random = Random()
val randomNumber = random.nextInt(10000000)
val customer = Customer("password", "password", "lastName", "firstName", "ted$randomNumber#gmail.com")
}
}
My build.gradle code looks like the following:
buildscript {
ext.kotlin_version = '1.1.4-3'
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath 'me.tatarka:gradle-retrolambda:3.7.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'kotlin'
repositories {
mavenCentral()
jcenter()
}
dependencies {
// some other compile dependencies
compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
testCompile "org.hamcrest:hamcrest-all:1.3"
testCompile 'junit:junit:4.11'
testCompile 'org.mockito:mockito-all:1.9.5'
testCompile "org.jetbrains.kotlin:kotlin-test"
testCompile "org.jetbrains.kotlin:kotlin-test-junit"
}
task javadocJar(type: Jar) {
classifier = 'javadoc'
from javadoc
}
task sourcesJar(type: Jar) {
classifier = 'sources'
from sourceSets.main.allSource
}
artifacts {
archives sourcesJar
archives javadocJar
}
compileKotlin {
kotlinOptions {
jvmTarget = "1.6"
}
}
compileTestKotlin {
kotlinOptions {
jvmTarget = "1.6"
}
}
The root build.gradle file looks as follows:
// Top-level build file where you can add configuration options
common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
maven {
url "https://jitpack.io"
credentials { username authToken }
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
ext {
versionName = "0.1.1"
rxJavaVersion = "2.1.3"
okHttpVersion = "3.9.0"
retrofitVersion = "2.3.0"
rxJava2AdapterVersion = "1.0.0"
googleGsonVersion = "2.8.0"
}
The error I get is that gradle cannot resolve Customer (Unresolved reference: Customer) in the Test class. It doesn't seem to include main classes into the test source directory. Yet, it resolves in the IDE.
Ok, I have found the solution. It seems I have to specify the src folders explicitly in my build.gradle and put all Kotlin code in src/main/kotlin and src/test/kotlin respectively.
sourceSets {
main.kotlin.srcDirs = ['src/main/kotlin', 'src/main/java']
main.java.srcDirs = []
test.kotlin.srcDirs = ['src/test/kotlin', 'src/test/java']
test.java.srcDirs = ['src/test/kotlin', 'src/test/java']
}
Once I did that, the tests started to work as expected - reports are even generated on Jenkins which is great.
I'm having difficulty generating a Grails 3.2.7 plugin with its dependencies.
This works and creates a JAR with all dependencies:
gradle clean build
..but not this; the JAR has no dependencies, just plugin project files:
gradle publishToMavenLocal
My gradle file, I know there's something missing, and based on the docs it's my understand there's no native feature to do this.
buildscript {
ext {
grailsVersion = project.grailsVersion

}
task sourceJar(type: Jar) {

}
publishing {

mavenJava(MavenPublication) {

}
}
The issue stems from the publishing section:
When I change this to:
task jarWithPlainPom(type: Jar) {
from sourceSets.main.output
from configurations.runtime
}
publishing {
publications {
mavenJava(MavenPublication) {
artifact jarWithPlainPom
}
}
}
It includes most of the needed dependencies, however the POM is not updated and the project fails when importing the plugin.
