``` FAILURE: Build failed with an exception.

* What went wrong: Could not resolve all files for configuration ':compileClasspath'. > Could not find com.example:some-library:1.0.0. Required by: project : ```

Or:

bash

* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all dependencies for configuration ':compileClasspath'.
   > Could not resolve com.example:lib:1.0.0.
     > Could not GET 'https://repo.maven.apache.org/maven2/com/example/lib/1.0.0/lib-1.0.0.pom'.

Or:

bash

* What went wrong:
Could not determine the dependencies of task ':jar'.
> Could not resolve all files for configuration ':runtimeClasspath'.
   > Could not find com.example:library:2.0.0.

Gradle build failures stem from dependency issues, configuration problems, or environment issues.

Common Causes

Configuration misconfiguration
Missing or incorrect credentials
Network connectivity issues
Version compatibility problems
Resource exhaustion or limits
Permission or access denied

Step-by-Step Fix

Step 1: Run with Detailed Logging

```bash # Run with stack trace ./gradlew build --stacktrace

# Run with full debug info ./gradlew build --debug

# Run with info level logging ./gradlew build --info ```

Step 2: Check Dependency Tree

```bash # Show all dependencies ./gradlew dependencies

# Show specific configuration ./gradlew dependencies --configuration compileClasspath ./gradlew dependencies --configuration runtimeClasspath

# Show dependency insight for specific dependency ./gradlew dependencyInsight --dependency com.example:library ```

Step 3: Check Available Tasks

```bash # List all tasks ./gradlew tasks

# List build tasks specifically ./gradlew tasks --group="build" ```

Step 4: Verify Gradle and Java Versions

```bash # Gradle version ./gradlew --version

# Java version used by Gradle java -version

# Check JAVA_HOME echo $JAVA_HOME ```

Step 5: Check Repository Configuration

bash

# View effective configuration
./gradlew properties | grep -A 10 repositories

Step-by-Step Fix

Solution 1: Fix Dependency Not Found

Add or correct repository in build.gradle:

```groovy repositories { // Primary: Maven Central mavenCentral()

// For Google libraries google()

// For JitPack (GitHub projects) maven { url 'https://jitpack.io' }

// For Spring milestones maven { url 'https://repo.spring.io/milestone' }

// For JBoss maven { url 'https://repository.jboss.org/nexus/content/groups/public/' } } ```

Verify dependency coordinates:

```groovy dependencies { // Check exact format: group:artifact:version implementation 'com.example:library:1.0.0'

// For platform/BOM imports implementation platform('com.example:bom:1.0.0')

// For local JAR files implementation files('libs/my-library.jar')

// For local directory implementation fileTree('libs') { include '*.jar' } } ```

Solution 2: Fix Version Conflicts

When dependencies conflict:

```groovy dependencies { // Force specific version implementation('com.example:library') { version { strictly '2.0.0' } }

// Or use force (deprecated but works) implementation('com.example:library:2.0.0') { force = true } } ```

Use resolution strategy:

```groovy configurations.all { resolutionStrategy { // Force specific version for all dependencies force 'com.example:library:2.0.0'

// Fail on version conflict failOnVersionConflict()

// Prefer modules from specific source preferProjectModules() } } ```

Solution 3: Clear Gradle Caches

```bash # Clear project build cache ./gradlew clean rm -rf build/ rm -rf .gradle/

# Clear global Gradle cache rm -rf ~/.gradle/caches/ rm -rf ~/.gradle/wrapper/dists/

# Rebuild with fresh cache ./gradlew build --refresh-dependencies ```

Solution 4: Fix Network/Proxy Issues

Configure proxy in gradle.properties:

```properties # HTTP Proxy systemProp.http.proxyHost=proxy.company.com systemProp.http.proxyPort=8080 systemProp.http.proxyUser=proxyuser systemProp.http.proxyPassword=proxypass

# HTTPS Proxy systemProp.https.proxyHost=proxy.company.com systemProp.https.proxyPort=8080 systemProp.https.proxyUser=proxyuser systemProp.https.proxyPassword=proxypass

# Non-proxy hosts systemProp.http.nonProxyHosts=localhost|127.0.0.1|*.internal.com ```

Or in build.gradle:

```groovy plugins { id 'java' }

// Proxy not needed in build.gradle usually // It's better to use gradle.properties ```

Solution 5: Fix Java Version Mismatch

When source/target compatibility is wrong:

```groovy // build.gradle java { toolchain { languageVersion = JavaLanguageVersion.of(17) } }

// Or specify source/target java { sourceCompatibility = JavaVersion.VERSION_17 targetCompatibility = JavaVersion.VERSION_17 }

// For Kotlin DSL (build.gradle.kts) java { toolchain { languageVersion.set(JavaLanguageVersion.of(17)) } } ```

If project requires specific Java version:

```bash # Set JAVA_HOME for Gradle export JAVA_HOME=/path/to/jdk-17 ./gradlew build

# Or use Gradle wrapper with specific Java ./gradlew build -Dorg.gradle.java.home=/path/to/jdk-17 ```

Solution 6: Fix Plugin Not Found

Add plugin repository:

```groovy // build.gradle buildscript { repositories { gradlePluginPortal() mavenCentral() google() } dependencies { classpath 'com.example:gradle-plugin:1.0.0' } }

// Or use plugins block plugins { id 'com.example.plugin' version '1.0.0' }

// For plugin portal plugins plugins { id 'java' id 'org.springframework.boot' version '3.2.0' } ```

Solution 7: Fix Multi-Module Dependencies

For multi-module projects:

```groovy // settings.gradle rootProject.name = 'myproject' include 'core', 'web', 'api'

// In web/build.gradle dependencies { // Reference another module implementation project(':core') implementation project(':api')

// External dependencies implementation 'org.springframework.boot:spring-boot-starter-web:3.2.0' } ```

Fix dependency ordering:

```groovy // In api/build.gradle dependencies { // Ensure core is built first implementation project(':core') }

// In web/build.gradle dependencies { // Both api and core will be built implementation project(':api') } ```

Solution 8: Fix Test Failures

When tests fail during build:

```bash # Run tests with more output ./gradlew test --info

# Run specific test ./gradlew test --tests "com.example.MyTest"

# Run tests in specific class ./gradlew test --tests "com.example.*Test"

# Continue build on test failure ./gradlew build --continue ```

Skip tests temporarily:

bash

# Build without running tests
./gradlew build -x test

Configure test in build.gradle:

```groovy test { useJUnitPlatform()

// Show test output testLogging { events "passed", "skipped", "failed" exceptionFormat "full" }

// Fail on first error failFast = true

// Parallel execution maxParallelForks = Runtime.runtime.availableProcessors().intdiv(2) ?: 1 } ```

Solution 9: Fix Kotlin DSL Issues

For build.gradle.kts:

```kotlin // Correct syntax plugins { java id("org.springframework.boot") version "3.2.0" id("io.spring.dependency-management") version "1.1.4" }

group = "com.example" version = "1.0.0"

java { sourceCompatibility = JavaVersion.VERSION_17 }

repositories { mavenCentral() }

dependencies { implementation("org.springframework.boot:spring-boot-starter-web") testImplementation("org.springframework.boot:spring-boot-starter-test") }

tasks.withType<Test> { useJUnitPlatform() } ```

Solution 10: Fix Permission Issues

```bash # Fix file permissions chmod +x gradlew

# Fix ownership chown -R user:user .

# Fix cache permissions chmod -R u+rw ~/.gradle/ ```

Verification

After fixes, verify the build:

```bash # Clean build ./gradlew clean build

# Check dependencies ./gradlew dependencies --configuration runtimeClasspath

# Verify specific task ./gradlew tasks

# Run with verbose output ./gradlew build --info --stacktrace

# Verify artifact ls -la build/libs/ ```

Create a diagnostic script:

```bash #!/bin/bash # diagnose-gradle.sh

echo "=== Gradle Diagnostics ==="

echo -e "\n--- Gradle Version ---" ./gradlew --version

echo -e "\n--- Java Version ---" java -version 2>&1 | head -3

echo -e "\n--- JAVA_HOME ---" echo "JAVA_HOME: $JAVA_HOME"

echo -e "\n--- Gradle Daemon Status ---" ./gradlew --status

echo -e "\n--- Configuration Check ---" ./gradlew properties | grep -E "(version|group|sourceCompatibility)"

echo -e "\n--- Dependency Check ---" ./gradlew dependencies --configuration compileClasspath 2>&1 | head -50

echo -e "\n--- Build Attempt ---" ./gradlew build --stacktrace 2>&1 | tail -30 ```

Common Error Patterns

Error	Cause	Solution
Could not find	Missing repository	Add mavenCentral() or other repo
Could not resolve	Version doesn't exist	Check correct version
Connection refused	Network/proxy issue	Configure proxy settings
Permission denied	File permissions	chmod +x gradlew
Unsupported class version	Java version mismatch	Update Java or toolchain
Plugin not found	Plugin repo missing	Add plugin portal
Circular dependency	Module depends on self	Fix project references
OutOfMemoryError	Build memory low	Increase Gradle memory

Increase Gradle Memory

For large projects:

```properties # In gradle.properties org.gradle.jvmargs=-Xmx4g -XX:+HeapDumpOnOutOfMemoryError -XX:MaxMetaspaceSize=512m

# Enable parallel builds org.gradle.parallel=true

# Enable caching org.gradle.caching=true

# Enable configuration cache org.gradle.configuration-cache=true ```

Quick Reference Commands

```bash # Clean everything ./gradlew clean && rm -rf .gradle/ build/

# Refresh dependencies ./gradlew build --refresh-dependencies

# See what went wrong ./gradlew build --stacktrace --info

# Check dependencies ./gradlew dependencies

# Build without tests ./gradlew build -x test

# Force rebuild ./gradlew clean build --no-build-cache ```

When Gradle build fails, run with --stacktrace first, then check dependencies and repositories. Clear caches as a last resort.
