Could not generate a proxy class for class com.android.build.gradle.tasks.BuildArtifactReportTask

I am getting an error on my Mac machine while cleaning the project using below in android studio terminal.

./gradlew clean

While I am cleaning the project using from Build->Clean project it is cleaning successfully.

I tried running the same project on another machine and it is getting cleaned successfully via terminal.

The complete error is below:

org.gradle.api.ProjectConfigurationException: A problem occurred configuring project ':app'.

A help would be appreciated.

No solution yet. I will update here if I find some solution.

I am also facing this problem too.

Which version of the jvm are we using? I’m using 1.8.0_20 (I think, openjdk, not sure how to tell. No, it’s oracle’s stuff, I think. I still don’t know how to properly tell, but the names of the packages in my downloads folder from ages ago are a good clue. Also, oracle’s current version is exactly at 181)

This thread seems to describe a similar problem, indicates that we might be able to get around this sort of thing by updating to 1.8.0_181 https://github.com/NativeScript/NativeScript/issues/6072

Okay. I tried it and it did work. Switching to openjdk via update-alternatives --config java also worked (once I’d made sure the open jdk itself was installed, along with the other stuff).
