I followed the steps in the README to update my project build.gradle and app build.gradle
When I build on Ubuntu Linux with
./gradlew clean assembleDebug
I get the following errors about missing annotations in CleanAndroidOpenCVBuildFolderTask:
FAILURE: Build failed with an exception.
* What went wrong:
Some problems were found with the configuration of task ':passthrough:cleanAndroidOpenCVBuildFolder' (type 'CleanAndroidOpenCVBuildFolderTask').
- In plugin 'com.ahasbini.android-opencv-gradle-plugin' type 'com.ahasbini.tools.androidopencv.task.CleanAndroidOpenCVBuildFolderTask' property 'description' is missing an input or output annotation.
Reason: A property without annotation isn't considered during up-to-date checking.
Possible solutions:
1. Add an input or output annotation.
2. Mark it as @Internal.

I tried your sample and when running it still asks for opencv manager.
Looking at the generated apk i see this
Though when running it checks for openv_info so lib which is not there:
Any idea?
PS: i am using opencv 4.1.1
Having setup the plugin as described, I get the following error when building the project:
ERROR: Not Found (HTTP status code: 404, URL: https://sourceforge.net/projects/opencvlibrary/files/3.4.3/opencv-3.4.3-android-sdk.zip)
As suggested by the error message the link that is being used does not seem to work.
The download link that is used when navigating manually via a browser is:
But that redirects to another site for the actual download, in my case:
I have followed the instructions and I always get this error:
ERROR: Failed to resolve: :opencv-debug:3.4.9
This is regardless of the OpenCV version I specify. I have tried with different ones.
I am using:
Android Studio 3.6.1
Gradle 3.6.1
Any help? Thanks.
Following the directions and the build will fail because the sample project tried to access the plugin before it is place.
I fixed the issue by first commenting out the line 'include 'sample'" in the gradle.settings the first time that ./gradlew :plugin:publishToMavenLocal is run
EDIT: I thought that I fixed but it has now failed with a new error, I'll list it here even though it might be a different issue:
