Gradle Syncing Problem with Kotlin and Jetpack Compose

Question

I'm encountering a syncing issue with Gradle while trying to set up a project with Kotlin and Compose Desktop.

Here's my build.gradle.kts file:

import org.jetbrains.compose.desktop.application.dsl.TargetFormat

plugins {
    kotlin("jvm")
    id("org.jetbrains.compose")
}
group = "io.crypto"
version = "1.0-SNAPSHOT"
repositories {
    mavenCentral()
    maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
}
dependencies {
    implementation(compose.desktop.currentOs)
}
compose.desktop {
    application {
        mainClass = "MainKt"
        nativeDistributions {
            targetFormats(TargetFormat.Dmg, TargetFormat.Msi, TargetFormat.Deb)
            packageName = "CryptoGraph"
            packageVersion = "1.0.0"
        }
    }
}

and here is setting.gradle.kts file:

    pluginManagement {
    repositories {
        google()
        gradlePluginPortal()
        maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
    }

    plugins {
        kotlin("jvm").version(extra["kotlin.version"] as String)
        id("org.jetbrains.compose").version(extra["compose.version"] as String)
    }
}

rootProject.name = "CryptoGraph"

here is my gradle.properties file:

org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8
kotlin.code.style=official
kotlin.version=1.9.20
compose.version=1.5.10

here is my gradle-wrapper.properties file:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

and here is the error I'm facing:

Build file '/home/mbunderline76/tick-viewer/CryptoGraph/build.gradle.kts' line: 3

I use Intellij Idea Ultimate 2023.3.2

here is my gradle --version-- command output:

Kotlin:       1.5.21
Groovy:       3.0.8
Ant:          Apache Ant(TM) version 1.10.9 compiled on September 27 2020

OS:           Linux 6.2.0-39-generic amd64

What could be causing this problem, and how can I resolve it?

Answer 1

After extensive troubleshooting, I managed to identify the root cause of the issue. The problem lay within the .gradle/gradle.properties file. I had proxy settings configured there, which interfered with the Gradle plugin resolution process.

To resolve this issue:

• Navigate to your project directory.
• Open the .gradle/gradle.properties file in a text editor.
• Locate any proxy-related settings and remove or comment them out.

After making these changes, I was able to successfully sync my Gradle project and resolve the plugin resolution error.

I hope this solution helps others facing a similar issue.
