Gradel Sync and build fail

[rayh0001]

Following the instructions using Android Studio 3.5.3 and gradel 5.4.1. I get the error:

Could not find method compile() for arguments [com.github.ibm-cloud-security:appid-clientsdk-android:6.+] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

I tried building the App ID Android sample while using your versions of Android Studio (3.5.3) and Gradle (5.4.1), and it builds and runs as expected.
Could you try downloading the App ID Android sample from the App ID dashboard and checking if the build works for you?

Also, can you share your app module's build.gradle file (not the project's build.gradle)?

Thanks @Ranibm. I was trying to add the sdk to an existing project, but the sample gave me a working model. plugin 3.3.2, with Gradel 4.10.2 seem to be ok now, anything higher causes some of the errors I shared before.
