Could not resolve all dependencies for configuration — how to fix

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileJava'.
> Could not resolve all dependencies for configuration ':app:compileClasspath'.
   > Could not find com.example:library:1.2.3.
     Required by:
         project :app

Quick fix: Read the nested Could not find/Could not GET line. Check the coordinates and version exist, add the right repository (mavenCentral(), google()) in settings.gradle / build.gradle, then run ./gradlew build --refresh-dependencies. Behind a proxy set systemProp.https.proxyHost/proxyPort in gradle.properties.

What it means

Before compiling, Gradle resolves every dependency in a configuration (compileClasspath, runtimeClasspath, debugRuntimeClasspath…). If any one fails, the whole configuration fails with this message. The real reason is in the indented lines below it — look for one of:

• Could not find group:name:version — no repository has that artifact.
• Could not GET 'https://...' / Connection refused / PKIX path building failed — network, proxy or TLS problem.
• Received status code 401/403 — authentication to a private repository.
• No matching variant — artifact exists but is incompatible (Java version, Android vs JVM).

Get more detail with:

./gradlew build --stacktrace --info
./gradlew :app:dependencies --configuration compileClasspath

Fix 1: wrong coordinates or version

Check the artifact really exists on search.maven.org or the vendor's repository. Typos in the group, artifact name or version are common, as are versions that were never published.

dependencies {
    implementation 'com.squareup.okhttp3:okhttp:4.12.0'
}

Fix 2: missing repository

Gradle only looks in repositories you declare. Android libraries live in google(); most others in mavenCentral(). JCenter is shut down — remove jcenter() and find the library elsewhere.

In modern projects repositories are in settings.gradle(.kts):

dependencyResolutionManagement {
    repositories {
        google()
        mavenCentral()
        maven { url = uri("https://jitpack.io") } // only if needed
    }
}

If repositoriesMode is FAIL_ON_PROJECT_REPOS, repositories declared in a module's build.gradle are ignored/rejected — add them here instead.

Fix 3: stale or corrupt cache

A failed download can be cached. Force Gradle to re-check:

./gradlew build --refresh-dependencies

If that does not help, stop daemons and remove the cached module:

./gradlew --stop
rm -rf ~/.gradle/caches/modules-2/files-2.1/com.example

Also make sure you are not in offline mode (--offline, or the Offline toggle in Android Studio / IntelliJ's Gradle panel).

Fix 4: proxy, firewall or TLS

Corporate networks often need a proxy. Add to ~/.gradle/gradle.properties:

systemProp.http.proxyHost=proxy.example.com
systemProp.http.proxyPort=8080
systemProp.https.proxyHost=proxy.example.com
systemProp.https.proxyPort=8080
systemProp.http.nonProxyHosts=localhost|*.internal

PKIX path building failed means a TLS-inspecting proxy's certificate isn't trusted by the JDK running Gradle. Import it into that JDK's truststore:

keytool -importcert -alias corp -file corp.crt -cacerts -storepass changeit

Fix 5: private repository credentials (401/403)

maven {
    url = uri("https://maven.pkg.github.com/OWNER/REPO")
    credentials {
        username = providers.gradleProperty("gpr.user").get()
        password = providers.gradleProperty("gpr.key").get()
    }
}

Put gpr.user and gpr.key in ~/.gradle/gradle.properties, not in the repo. GitHub Packages requires a token even for public packages.

Fix 6: variant / Java version mismatch

No matching variant ... compatible with Java 8 means the library needs a newer JVM. Raise the toolchain:

java { toolchain { languageVersion = JavaLanguageVersion.of(17) } }

Or choose an older library version that supports your Java version.
