Firebase Performance Monitoring, Can't instrument...IllegalArgumentException

Question

I'm using implementation 'com.google.firebase:firebase-perf:19.0.5'

I applied the plugin: apply plugin: 'com.google.firebase.firebase-perf'

and in my project level gradle: classpath 'com.google.firebase:perf-plugin:1.3.1'

I'm running into a few issues. 1) during my build, I see a lot of Can't instrument exceptions like this:

Can't instrument: kotlin/reflect/jvm/internal/impl/load/java/lazy/descriptors/LazyJavaClassMemberScope$nestedClasses$1$enumMemberNames$1.class

2) I only see logging TraceMetric and no NetworkRequestMetric. the API calls are using Retrofit2, which uses OkHttp3

Answer 1

I had the same issue, and the fix was to move the classpath of the firebase performance before the other plugin that has the dependency to the "org.ow2.asm:asm"(in the project level gradle file).

  dependencies {
    classpath 'com.google.firebase:perf-plugin:1.3.1'
    classpath "org.jacoco:org.jacoco.core:$jacoco_version"
    ...
 }

Firebase plugin uses version 7.0 of the org.ow2.asm:asm Jacoco plugin uses 5.+ of the org.ow2.asm:asm

To check the versions you can try to use ./gradlew buildEnvironment

Maybe you have the same issue as me.
