java.lang.NoClassDefFoundError

[AlexandruHulpe94]

We have some unit tests in our project which are passing without any issues when run locally but are failing with this: java.lang.IllegalStateException at PluginLoader.java:88 Caused by: java.lang.IllegalStateException at PluginInitializer.java:58 Caused by: java.lang.reflect.InvocationTargetException at NativeConstructorAccessorImpl.java:-2 Caused by: org.mockito.exceptions.base.MockitoInitializationException at InlineDelegateByteBuddyMockMaker.java:244 Caused by: java.lang.NoClassDefFoundError at InlineDelegateByteBuddyMockMaker.java:115 Caused by: java.lang.ClassNotFoundException at BuiltinClassLoader.java:641 kotlin.UninitializedPropertyAccessException at BaseTestCase.kt:22 when they are run with koverReport.

Kover version "0.6.0-Beta" compileSdkVersion = 33 minSdk = 21 targetSdk = 33 Kotlin version "1.6.1"

Hi, may you clarify if this error is reproduced on version 0.5.1? Could you provide a reproducer of this issue?

[AlexandruHulpe94]

If you see at the final I put all the used versions. Kover version "0.6.0-Beta"

[shanshin]

Thanks. If the previous version 0.5.1 is used instead of 0.6.0-Beta, then the error is also reproduced?

[AlexandruHulpe94]

Yes. It's also reproduced with 0.5.1 as well.

[shanshin]

Is your project open-source? The reproducer would be very helpful

[AlexandruHulpe94]

The project is not open source. Have a look at the unit test and stacktrace please.

[AlexandruHulpe94]

@shanshin Please see above.

[shanshin]

Could you provide a full error stack trace, or at least an error message for exceptions java.lang.NoClassDefFoundError and java.lang.ClassNotFoundException?

Unfortunately, it is not clear from this stacktrace which class was not found. Do you have the opportunity to find out for which class java.lang.NoClassDefFoundError is thrown?

Are you using a Kover plugin with the JaCoCo engine?

If you use ProGuard/R8, are JaCoCo classes added to exceptions? Judging by the error, the JaCoCo org.jacoco.agent.rt.internal_3570298.PreMain class was shrinked.

Feel free to open new bug issue if the problem reproduced again.
