Could not resolve a dependency

Error text

Could not resolve com.squareup.okhttp3:okhttp:4.12.0.
Required by: project :app

Cause

Gradle could not find the named library in any repository. The name, the version, or the repository list is wrong.

Step-by-step fix

1. Check group, name and version letter by letter; one typo is enough.
2. If the library lives outside Google and Maven Central (for example on JitPack), add its maven { url ... } line.
3. Check the network: does the repository address open in a browser?
4. Run ./gradlew build --refresh-dependencies.
5. If you wrote a floating version (+), replace it with an exact number.

Example commands

./gradlew :app:dependencies | grep -i okhttp
./gradlew build --offline    # ancaq yerli keşlə yoxlamaq üçün

How to prevent it

Always pin exact versions. A + makes the same build behave differently on different days.
