When I add the dependency com.squareup.okhttp3:okhttp:5.1.0 to build.gradle.kts (app module), apply the "Replace with new library catalog declaration" quickfix, and I run the build task ./gradlew build, I get the following java.lang.IllegalArgumentException: source must not be null error:

Reproduction steps:

  1. Create a new empty activity kotlin project
  2. Open the build.gradle.kts (Module :app) file
  3. Add implementation("com.squareup.okhttp3:okhttp:5.1.0") to the dependencies list
  4. Run "sync now" as prompted
  5. Run a Gradle build --> The build will be successful
  6. Position the cursor on the implementation("com.squareup.okhttp3:okhttp:5.1.0") line
  7. Click on the lightbulb and select Replace with new library catalog declaration for okhttp
  8. The line will change to implementation(libs.okhttp)
  9. Run "sync now" again
  10. Run a Gradle build --> The build will now fail with the java.lang.IllegalArgumentException: source must not be null error

  • "NOTE: Scroll to the bottom for the exact reproduction steps" -- what version of Android Studio are you using? What version of Gradle and the Android Gradle plugin are you using? Commented Sep 23 at 19:13
  • @CommonsWare I'm on Gradle 8.13, Android Studio 2025.1.3, Android Gradle Plugin 8.13.0 Commented Sep 23 at 20:59
  • FWIW, I get that error already on step 5, if I choose Build | Assemble 'app' Run Configuration from the main menu. It might be related to this bug report. You might consider filing a bug report with your repro steps, though, as while the linked-to issue has the same crash, the repro steps seem substantially different than yours.

  • @CommonsWare Thank you for the bug report link, i will consider filing a report. Commented Sep 24 at 12:40
  • I'm experiencing the same error. I just made a post about it here Commented Sep 26 at 10:03

I fixed this issue by reverting to okhttp 4.12.0. So using com.squareup.okhttp3:okhttp:4.12.0.

You can also apply the quickfix without issues.

Another fix (even better) is updating the core dependencies in the libs.versions.tom:

kotlin = "2.2.20"
composeBom = "2025.09.01"
okhttp = "5.1.0"

This will work perfectly after a ./gradlew clean
