Cannot build an Android app with Gradle, except with sudo

Question

I am trying to run a simple 'hello world' android app with gradle build. It builds fine if I issue the command

sudo ./gradlew build --> builds fine

But without sudo,

./gradlew build --> shows following error

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':MyStudioApplication'.
> Failed to notify project evaluation listener.
   > Could not resolve all dependencies for configuration ':MyStudioApplication:_DebugCompile'.
      > Could not find any version that matches com.android.support:appcompat-v7:+.
        Required by:
            workspace:MyStudioApplication:unspecified

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 12.621 secs

following is my build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
}

Please help

Taking a shot in the dark here, you may have run your initial gradle build with sudo which may have caused the artifacts to be downloaded and permisionned to root and are not accessible to your regular user. To test this assumption you may want to rename your local repository where gradle downloads the dependencies and rerun gradle as the standard user.
