Groovy error when using Mint Android SDK plugin and other libraries

[derrickrc]

EDIT: I modified my gradle to follow the instructions for "Use the Android SDK without MINT instrumentation" instead of "with" and it seems to be building now with no conflicts

What kind of issue is this?

Hello,

I am not sure if this is more Mint or Groovy related, but thought I would also try here - I am using the Mint SDK for my Android project per these instructions: https://docs.splunk.com/Documentation/MintAndroidSDK/5.2.x/DevGuide/AddSplunkMINTtoyourproject

It has been working great. However, I am getting build errors in two cases that I believe are due to a line of code in the Mint SDK which is related to groovy. When I comment out "apply plugin: 'com.splunk.mint.gradle.android.plugin'" in my app level gradle, the app builds successfully.

1. I imported a new module that utilizes Lambda expressions and Java 8.

org.gradle.api.GradleException: The type java.lang.invoke.LambdaMetafactory cannot be resolved. It is indirectly referenced from required .class files at com.splunk.mint.gradle.android.AspectjCompile.compile(AspectjCompile.groovy:73)

2. When I try to install Firebase Performance Monitoring:

Expecting .,<, or ;, but found firebaseperf while unpacking <K:Ljava/lang/Object;>Lcom/google/android/gms/internal/firebase-perf/zzw<TK;>;
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':usbSerialExamples:compileDebugMINTInstrumentation'. at com.splunk.mint.gradle.android.AspectjCompile.compile(AspectjCompile.groovy:73) at
