internal dependency conflict appears when compiling google-cloud-pubsub

[kir-titievsky]

Reposting this submission to cloud-pubsub-discuss@googlegroups.com as a bug:

The cloud pubsub library is not working with Android Studio 2.2.1 (Build #AI-145.3330264, built on October 6, 2016, JRE: 1.8.0_76-release-b03 amd64, JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o) under Debian (3.2.0-4-amd64 #1 SMP Debian 3.2.81-2 x86_64 GNU/Linux).

I added [compile group: 'com.google.cloud', name: 'google-cloud-pubsub', version: '0.4.0'] to gradle file, but it states the following: "Execution failed for task ':app:prepareDebugAndroidTestDependencies'.>Dependency Error. See console for details."

I checked the console and the output shows the following: "Conflict with dependency 'com.google.code.findbugs:jsr305'. Resolved versions for app (3.0.0) and test app (2.0.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.".

I tried to solve it by adding the following line to the android{} section of gradle file: "configurations.all { resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.0' }", but it resulted in the following output in console(see below):
"Error:FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

What should I do?

@kir-titievsky I'll try to have a look at this. First and second errors appear to be unrelated though. Also please, be aware that we do not explicitly support Android at the moment.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/LICENSE

This kind of duplication errors seems to be quite common in Android. To avoid duplication you could try adding to your build file:

packagingOptions {
    exclude 'META-INF/LICENSE'
}

Hi,

Just want to update it with the recent gradle configuration:

Gradle:

apply plugin: 'com.android.application'

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 group: 'com.google.cloud', name: 'google-cloud-pubsub', version: '0.4.0'
compile 'com.android.support:appcompat-v7:23.4.0'
testCompile 'junit:junit:4.12'

}

android {
compileSdkVersion 23
buildToolsVersion '24.0.3'
defaultConfig {
applicationId "com.example.debi.pubsub0"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

configurations.all {
    resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.0'
}

packagingOptions {
    pickFirst 'META-INF/LICENSE'
    pickFirst  'META-INF/io.netty.versions.properties'
    pickFirst 'META-INF/INDEX.LIST'
}

/*packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude  'META-INF/io.netty.versions.properties'
    exclude 'META-INF/INDEX.LIST'
}*/

}

Console:

Information:BUILD FAILED

Some warnings have been suppressed using 'pickFirst' or 'exclude' methods, but it doesn't seem to go beyond that. The problem disappears only if "compile group: 'com.google.cloud', name: 'google-cloud-pubsub', version: '0.4.0'" gets removed from dependencies(other libraries work fine).

Thanks.

Hi @jfarkhat,
try replacing:

compile group: 'com.google.cloud', name: 'google-cloud-pubsub', version: '0.4.0'

with:

compile ('com.google.cloud:google-cloud-pubsub:0.4.0') {
    exclude group: 'com.google.api-client', module: 'google-api-client-appengine'
}

This should exclude the dependency that is causing troubles.

[mziccard]

Could you please format your previous posts? Also please don't cut-and-paste these long logs but rather attach a public gist to your post.

Are you excluding other artifacts in addition to the one I suggested you to exclude?

[jfarkhat]

I am sorry :)))

Here is the output2 from adding the 3rd line of the code to MainActivity:
PubSubOptions.Builder optionsBuilder = PubSubOptions.builder();
optionsBuilder.projectId("project-id");
PubSub pubsub = optionsBuilder.build().service();

https://gist.github.com/jfarkhat/3fcdce92eba2a918ef6163c89a3f9913

I excluded 'group: 'com.google.api-client', module: 'google-api-client-appengine'

[mziccard]

@jfarkhat I had a deeper look at this, try adding this dependency:

compile group: 'com.google.api-client', name: 'google-api-client', version: '1.21.0'

[jfarkhat]

Hi,
Compile group: 'com.google.api-client', name: 'google-api-client', version: '1.21.0' didn't work(the same errors). But the issue is no longer a problem and I found much simpler solution to it. Thanks )
