More than one file was found with OS independent p

Question

When i build my app, I got follow error .

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'. More than one file was found with OS independent path 'META-INF/LICENSE'

This is My build.gradle file

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "cn.sz.cyrus.kotlintest"
        minSdkVersion 14
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        javaCompileOptions{
            annotationProcessorOptions{
                includeCompileClasspath = true
            }
        }
        multiDexEnabled true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
 /*       exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'*/
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
    compile 'com.android.support:appcompat-v7:25.3.1'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5.1'
    releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.1'
    testCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.1'
    compile 'com.github.GrenderG:Toasty:1.2.5'
    compile 'com.orhanobut:logger:1.15'

    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
    compile 'com.umeng.analytics:analytics:latest.integration'
    compile 'ai.api:libai:1.4.8'
    compile 'ai.api:sdk:2.0.5@aar'
// api.ai SDK dependencies
    compile 'com.google.code.gson:gson:2.8.0'
    compile 'commons-io:commons-io:2.4'
    compile 'com.android.support:multidex:1.0.1'
}

when I add those code to my gradle file.

  packagingOptions {
            exclude 'META-INF/DEPENDENCIES'
            exclude 'META-INF/NOTICE'
            exclude 'META-INF/LICENSE'
            exclude 'META-INF/LICENSE.txt'
            exclude 'META-INF/NOTICE.txt'
        }

This error would be solved , but another problem will happen. like this

java.lang.NoClassDefFoundError: com.squareup.leakcanary.internal.HeapAnalyzerService
at com.squareup.leakcanary.LeakCanary.isInAnalyzerProcess(LeakCanary.java:145)
at cn.sz.cyrus.wemz.TestApplication.onCreate(TestApplication.kt:32)

Who has ideas how to solve this?

Answer 1

I'm having same problem and I tried this

Error: More than one file was found with OS independent path 'META-INF/library_release.kotlin_module'

Solution:

android {
    packagingOptions {
    exclude 'META-INF/library_release.kotlin_module'
    }
}

Worked for me....

Answer 2

I faced this issue, first with some native libraries (.so files) and then with java/kotlin files. Turned out I was including a library from source as well as referencing artifactory through a transitive dependency. Check your dependency tree to see if there are any redundant entries. Use ./gradlew :app:dependencies to get the dependency tree. Replace "app" with your module name if the main module name is different.

Answer 3

I my app, I was adding the jar dependencies like this:

implementation files('libs/json-simple-1.1.1.jar')

But I realised that they were already added because of the following first line in dependencies:

implementation fileTree(include: ['*.jar'], dir: 'libs')

This line adds all the jars in lib folder to app dependency.

Hence after removing the extra dependency implementation files('libs/json-simple-1.1.1.jar')

it is working fine.

Answer 4

In my case it was enough to exclude only path 'META-INF/LICENSE' on yourProject/app/build.gradle inside android{} . Here it is

packagingOptions {
    exclude 'META-INF/LICENSE'
}

And then do Clean Project and Rebuild Project.

Answer 5

You can add this in yourProject/app/build.gradle inside android{}

android {

      packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
      }

    }

Answer 6

Basically when gradle puts together the apk file, it copies content from all the compile dependencies, It is intelligent enough to see that there is a duplicate file..coming from two different jar files. This could be any file like a.txt or META-INF/DEPENDENCIES. It might be best to exclude these files using the below, in case the file is present there only for informational purposes.

android{
    packagingOptions {
       exclude 'META-INF/DEPENDENCIES'
    }
}

Or if in case, the file is a mandatory file like a class file, that has been duplicated across two jar dependencies that are related to each other, it is best to find alternatives to these jars, in the way of a more compatible version.
