Question

I am having trouble building a simple android project using Gradle. My build file is below:

buildscript {
    repositories {
      mavenCentral()
      // To use a development snapshot version of the plugin, add the
      // Sonatype Snapshots repository.
      maven {
        url "https://oss.sonatype.org/content/repositories/snapshots"
      }
    }

    dependencies {
      classpath 'org.gradle.api.plugins:gradle-android-plugin:1.2.1'
    }
  }

  apply plugin: 'android'

  repositories {
      mavenCentral()
  }

  // Sets the package version
  version = "1.0.0"



  // Signing configuration, valid for all builds (1)
  androidSignAndAlign {
    keyStore = "path/to/my/keystore"
    keyAlias = "my-key-alias"
    keyStorePassword = "mystorepass"
    keyAliasPassword = "myaliaspass"
  }

  // Configure the filtering of resources with properties from the Gradle's project scope (2)
  processResources {
    expand (project.properties)
  }

  // Configure a dedicated debug build (3)
  task configureDebug << {
    jar.classifier = "debug"
  }

  // Configure a dedicated release build (4)
  task configureRelease << {
    proguard.enabled = true
  }

The error i get is this:

  11:08:24.812 [ERROR] [org.gradle.BuildExceptionReporter] FAILURE: Build failed with an exception.
11:08:24.822 [ERROR] [org.gradle.BuildExceptionReporter]

using gradle 1.2

edit: here is my layout xml file

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

</RelativeLayout>

And here is the actvivity

public class RssListActivity extends Activity {

    /*
     * (non-Javadoc)
     * @see android.app.Activity#onCreate(android.os.Bundle)
     */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.list_activity_layout);
    }

}

Here is what is in the root folder of the project

AndroidManifest.xml  assets  bin  build  build.gradle  gen  gradle.properties  ic_launcher-web.png  local.properties  project.properties  res  src

And finaly the android manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.richy.rssunified"
    android:versionCode="1"
    android:versionName="1.0">

    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" />

    <application android:label="@string/app_name"
        android:icon="@drawable/ic_launcher"
        android:theme="@style/AppTheme">

    </application>

</manifest>

sdk.dir = C:/Program Files (x86)/Android/android-sdk

edit:

i have reverted back to older version of the adt/sdk plugins and managed to fix the issues above, however after i did that, i now get the above error below:

Answer 1

As is described in:
http://tools.android.com/tech-docs/new-build-system/using-the-new-build-system#TOC-Working-with-and-Customizing-SourceSets

Default sourceset location is under src/<sourceset>

Your sourceset name is main so location is src/main

Additionally, manifest property is described:

manifest, type AndroidSourceFile, default location src/<sourceset>/AndroidManifest.xml

I guess that declaration of manifest:

   manifest {
                srcFile 'AndroidManifest.xml'
            }

is same as default and ends up with location:

src/main/AndroidManifest.xml

which is listed in exception message.

I think this is how gradle android plugin works.
Correct me if I’m wrong, I don’t know Gradle.

EDIT

Ok, now I know what’s wrong. Your build script mixes settings from two different plugins.

Change:

classpath 'com.android.tools.build:gradle:0.1'

to

classpath 'org.gradle.api.plugins:gradle-android-plugin:1.2.1'

Remove android block, but keep the body.

Remove sourceSets block with body.

Then it should work, I tested it this time.

EDIT 2

This is Windows related bug, fixed 6 days ago:

https://github.com/jvoegele/gradle-android-plugin/pull/89

that what you can do is to download latest plugin version

git clone git://github.com/jvoegele/gradle-android-plugin.git

and install it in local maven repository:

gradle install

then add mavenLocal() to repositories:

repositories {
    mavenCentral()
    mavenLocal()
}

and change plugin version to the snapshot:

dependencies {
    classpath 'org.gradle.api.plugins:gradle-android-plugin:1.2.2-SNAPSHOT'
}
