Question

I am trying to create a build script using gradle to build a android project and using plugins from eclipse and android but it doesnt seem to work and failes with the following error when I run gradle eclipse:

* What went wrong:
A problem occurred evaluating root project 'RssUnified'.
Cause: Could not find method apply() for arguments [{plugin=eclipse}] on root project 'RssUnified'.

Here is my build script:

//apply eclipse plugin
apply plugin: 'eclipse'

//apply android plugin
apply plugin: 'android'

task hello << {
    String value = 'wagwan'

    println 'Hello world!' + value.toUpperCase()
}

//setup external dependancy plugins we will use to build a android application
repositories {
    mavenCentral()
}

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

Gradle exception thrown below:

Exception in thread "main" java.lang.NoClassDefFoundError: org/gradle/BootstrapMain
Caused by: java.lang.ClassNotFoundException: org.gradle.BootstrapMain

Could not find the main class: org.gradle.BootstrapMain.  Program will exit.

I downloaded full gradle version from this link: http://www.gradle.org/downloads

Version 0.8 did not support the apply syntax for plugins yet. Starting with version 0.9 the apply method was introduced. A similar issue is described in this post.

Version 0.8 is pretty old. I’d highly recommend upgrading to the latest version of Gradle. That should definitely fix your problem.
