paparazzi: Java 17 incompatibility - `UnsupportedOperationException: class redefinition failed: attempted to delete a method`

AGP will require JDK 17, which means that gradlew (JAVA_HOME and AS Settings) has to use JDK 17 (note, AS itself doesn’t!), but Gradle added beautiful toolchain support (and even before that it was possible) to be able to easily define JDK running different tasks. So with a few lines we should be able to still work around this:

tasks.withType<KotlinCompile>().configureEach {
    kotlinOptions.jvmTarget = "11" // lower byte-code level so that Test can load classes.
}
tasks.named("test").configure {
    javaLauncher = javaToolchains.launcherFor {
      languageVersion = JavaLanguageVersion.of(11)
    }
}

I am still seeing the same error even after removing test Coverage flags and the test does not have @RunWith(AndroidJUnit4::class) or Robolectric

I am using JDK 17, kotlin 1.8.21, Gradle 8.1.1, AGP 8.0.2, paparazzi 1.3.0.

so based on all the input, the issue here is using @RunWith(AndroidJUnit4::class) or Robolectric with Paparazzi which is tracked by this issue https://github.com/cashapp/paparazzi/issues/425

I’m going to leave this issue open for a bit until the PR above is merged, but paparazzi is now on AGP 8.0 and built with Java 17 and is working as expected.

The workaround also doesn’t work for us

Removing jacoco plugin solves this for me. Not clear how to solve this with jacoco enabled though.

This is something I already tried, and it was promising at the beginning making the test to pass. It even created a report in build directory. But I made some minor changes and subsequent executions failed. I reverted to the same code but since then I always got that error. No matters what I do, still happens the same.

Right now I have changed my JDK to JDK 17 with no luck. After that I also changed my kotlinOptions and compileOptions to also use VERSION_17, and again: fails
