Error: Unable To Load Class


I recent I am working on a task and when I configure the API, I got this- Error: Unable to load class- ‘org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Could not open proj generic class cache for build file '/path/to/project/app/build.gradle' (/path/to/gradle/caches/proj-generic/
   > Unable to load class 'org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration' due to missing dependency 'org/gradle/internal/impldep/com/google/common/collect/ImmutableList'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

* Get more help at

When I reach about this, I came across these articles/resources mulesoft interview questions Gradle Error org.gradle.api.internal.artifacts, and as per them, this error can occur due to class loading issues, possibly from a corrupted Gradle cache or mismatched Gradle version. When I check the status, everything is find even I am removed all the cache and having latest gradle version, then what could be the reason?

Kindly provide solution.


I’m not sure what you mean with those two links. The first does not contain the word “Gradle” and in the second I just asked for more information and never got any feedback.

And like there, I can just say the same. To even have a chance of someone figuring out, provide the full error including --stacktrace or at even better a build--scan URL.
