Gradle未能应用插件FatJar

Question

我下载了一个使用Gradle的项目，解压缩它，在该目录中打开一个cmd提示符并运行gradle。我得到以下信息：

Y:\cuchaz-enigma-853f818ee7ac>gradle build
FAILURE: Build failed with an exception.
* Where:
Build file 'Y:\cuchaz-enigma-853f818ee7ac

* What went wrong:
A problem occurred evaluating root project 'cuchaz-enigma-853f818ee7ac'.
> Failed to apply plugin [id 'fatjar']
   > Could not find method add() for arguments [fatJarPrepareFiles, class eu.app

下面是Build.Gradle：

buildscript {

        mavenCentral()

    dependencies {
        classpath "eu.appsatori:gradle-fatjar-plugin:0.2-rc1"

    }
}

apply plugin: "maven"
apply plugin: "fatjar"

    outjars( "build/libs/test${name}.obf.jar" )
}

task obfTestCases( dependsOn: tasks.withType( proguard.gradle.ProGuardTask ) )

我已经下载了Jar，把它放在Lib和Plugins中，确保这个文件也存在于我的Gradle Cache中，但是它仍然是错误的。有什么想法吗？谢谢。

看起来插件的标识符已经改变了。我还建议使用该插件的最新版本。请注意，版本0.3只在JCenter上可用，而在Maven Central中没有。

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath "eu.appsatori:gradle-fatjar-plugin:0.3"
    }
}

apply plugin: 'eu.appsatori.fatjar'
