Duplicate files copied in APK META-INF/maven/org.bytedeco.javacpp-presets

[Menegussi]

Hi all,

I need help about this:

I'm trying to use javacv for android in a OCR Application example from RM Theis Tesseract project.

For this I've put the gradle dependences with the another project example of javacv android. Follows bellow  the gradle file that  I made:

//-----------------------------------------------------------------------------------------------

apply plugin: 'com.android.application'

android {

    compileSdkVersion 19

    buildToolsVersion "24.0.2"

    defaultConfig {

        applicationId "edu.sfsu.cs.orange.ocr"

        minSdkVersion 9

        targetSdkVersion 10

    }

    buildTypes {

        release {

            minifyEnabled true

            proguardFiles 'proguard.cfg'

        }

    }

}

dependencies {

    compile 'com.rmtheis:tess-two:6.0.4'

    compile files('libs/google-api-translate-java-0.98-mod2.jar')

    compile files('libs/json_simple-1.1.jar')

    compile files('libs/jtar-1.0.4.jar')

    compile files('libs/microsoft-translator-java-api-0.6-mod.jar')

//------------- I've  put this part to include javacv in the project:

    compile group: 'org.bytedeco', name: 'javacv', version: '1.3.2'

    compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3', classifier: 'android-arm'

    compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3', classifier: 'android-x86'

    compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.2.1-1.3', classifier: 'android-arm'

    compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.2.1-1.3', classifier: 'android-x86'

}

 I can sync gradle and not become no errors. But if I start to run the app, it shows me these errors:

Error:Execution failed for task ':OCRTest:transformResourcesWithMergeJavaResForDebug'.

These javacv parte I got from the javacv android example. And the javacv android example runs fine.

Can Anyone help me clarify what I need to do? I searched on web but the possible solutions didnt work for me.

Thx!

Hi,

We can take care of such duplicate files by using the "exclude" or "pickFirst" packageOptions.
Some examples here: https://github.com/bytedeco/javacv/issues/353

I'm still looking for someone to summarize this information and create a wiki page about that!
If you could make a contribution, it would be most welcome.
