我觉得这工作得很好，上周我的桌面上，但我试图复制它在我的笔记本电脑并没有什么似乎工作（到位桶克隆库）。这是我的摇篮：

I thought this worked fine last week on my desktop but I'm trying to replicate it on my laptop and nothing appears to be working (cloned bitbucket repository). Here is my gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.google.appengine:gradle-appengine-plugin:1.9.1'
    }
}

repositories {
    mavenCentral();
}

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'appengine'

sourceCompatibility = 1.7
targetCompatibility = 1.7

dependencies {
  appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.1'
  compile 'com.google.appengine:appengine-endpoints:1.9.1'
  compile 'com.google.appengine:appengine-endpoints-deps:1.9.1'
  compile 'javax.servlet:servlet-api:2.5'

    // Persistence
    compile 'org.ow2.asm:asm:4.0'
    compile 'org.datanucleus:datanucleus-api-jpa:3.1.3'
    compile 'org.datanucleus:datanucleus-api-jdo:3.1.3'
    compile 'com.google.appengine.orm:datanucleus-appengine:2.1.2'
    compile 'org.datanucleus:datanucleus-core:3.1.3'
    compile 'org.apache.geronimo.specs:geronimo-jpa_2.0_spec:1.0'
    compile 'javax.jdo:jdo-api:3.0.1'
    compile 'javax.transaction:jta:1.1'

}

appengine {
  downloadSdk = true
  appcfg {
    oauth2 = true
  }
  endpoints {
    getClientLibsOnBuild = true
    getDiscoveryDocsOnBuild = true
  }
}
