Error trying to import AppD plugin

[Ulises_Martine1]

Hi team,

I'm am just trying to import the Appd plugin inside an android library:

apply plugin: 'com.android.library'
apply plugin: 'adeum' // this line added for AppDynamics

But always with this error:

A problem occurred configuring the project ':mylibrary'.
> Failed to notify the project evaluation listener.
> Transforms with scopes '[EXTERNAL_LIBRARIES, SUB_PROJECTS]' cannot be applied to library projects.
> Cannot cast object 'extension 'android'' with class 'com.android.build.gradle.LibraryExtension_Decorated' to class 'com.android.build.gradle.AppExtension'

I tried with a bunch of versions of Gradle and the plugin without a different outcome:

dependencies {
    classpath 'com.android.tools.build:gradle:4.0.0'
    classpath 'com.appdynamics:appdynamics-gradle-plugin:20.7.1' // this line added for AppDynamics
    

From the 3.0.X of Gradle till the last one 4.1.0 (October 2020 )

From the plugin version --- 4.5.X till 20.10.2

Hope someone can help me with this issue 🙂

Hi all,

@Ulises.Martinez Uribe reached out to support and this was their response.

The AppDynamics Gradle plugin is complaining that it is being applied to a library, which is not supported. We only work with apps. Our instrumentation will be applied to any library that's linked in.

Hi Team !!!

In fact I reached support and they told me that the android plugin is complaining that it is being applied to a library, which is not supported..

Why I was trying to instrument a library ?  well this is a specific use case that is not in the Appdynamics supported use cases...

The use case is the next one... My customer is a credit card payment system that allow other apps to import their libraries and use that functionality in their own apps (imagine you are a retail company and wants to implement credit card payment)

So that looks like a weird case, and the main questions are...

1.- who is gonna pay for the license ?

2.- who should be on charge of that monitoring.. ?

So the AppDy support team just told me that for that kind of things, we can instrument just the app not an independent library ....

end of the story 🙂
