Failed to call IncrementalTask.taskAction () for task: mergeDebugAssets'

Question

I tried to debug this problem for ages. Honestly, I am not very familiar with Android Studio, so I would appreciate help. When I go to create the application, I get the following:

Gradle: Execution failed for task ':mergeDebugAssets'. > Could not call IncrementalTask.taskAction() on task ':mergeDebugAssets' 

Here is my build.gradle file:

 buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.6+' } } apply plugin: 'android' apply plugin: 'newrelic' repositories { mavenCentral() } dependencies { compile fileTree(dir: 'libs', include: '*.jar') } android { compileSdkVersion 17 buildToolsVersion "17.0.0" sourceSets { main { manifest.srcFile 'AndroidManifest.xml' java.srcDirs = ['src'] resources.srcDirs = ['src'] aidl.srcDirs = ['src'] renderscript.srcDirs = ['src'] res.srcDirs = ['res'] assets.srcDirs = ['assets'] } instrumentTest.setRoot('tests') } } buildscript { dependencies { classpath 'com.newrelic.agent.android:agent-gradle-plugin:2.397.0' } } repositories { mavenCentral() } apply plugin: 'android' apply plugin: 'newrelic' dependencies { compile 'com.newrelic.agent.android:android-agent:2.397' } 

And here is the output ./gradlew --stacktrace assembleDebug

Answer 1

It sounds like a bad installation of the Android Gradle plugin. Make sure that you are on the latest version, 0.6.3 or later (0.6.2 had problems, and we had to quickly unscrew the new version), and everything should be in order. If you still have problems, I would try to erase the Gradle cache directory ( .gradle/caches in your home directory, as a rule) and try again.

Answer 2

As Josh Wong said, the answer is: Gradle Error - Failed to call IncrementalTask.taskAction () on task ': project: mergeDebugResources .

Dimeji Isola's answer:

So, after reading on gradle, I tried this command "gradlew compileDebug --stacktrace" to see a more detailed error. Turns out the problem was actually a duplicate resource problem, and gradle just gave me a general error.
