Zero ICE demo

在Zeroc ice 官网 https://zeroc.com/distributions/ice

给出的ice-demo地址 git clone -b 3.6 https://github.com/zeroc-ice/ice-demos.git

下来之后还要装 Berkeley DB，执行gradlew build时还是各种错.

于是就下载了 git clone https://github.com/zeroc-ice/ice-demos.git，然而master的代码并不能正常build

ice-demo的正确打开方式
1.下载ice： https://zeroc.com/distributions/ice  上有各种平台的安装方法，这次测试是在windows 7上安装的，最好安装到ice默认的安装路径下，不要相信gradle.properties 文件中的iceHome配置，已尝试过各种配置，都无法生效，如果有配置成功的同学可以留言指导一下，如果按照默认配置，应该就跨过了一个大坑

2.下载demo  git clone https://github.com/zeroc-ice/ice-demos.git 需要用到git
3. cd ice-demos 执行gradlew build 会出现下面的错误

* What went wrong:
A problem occurred evaluating script.
> Could not resolve all dependencies for configuration ':demoIceDiscoveryHello:runtime'.
   > Could not find com.zeroc:icediscovery:null.
     Searched in the following locations:

解决办法：找到ice-demo/java/gradle/ice.gradle,在文件末尾加入

<span style="font-size:18px;">dependencies {
    compile 'com.zeroc:ice:3.6.2'
    compile 'com.zeroc:icediscovery:3.6.2'
    compile 'com.zeroc:icebox:3.6.2'
    compile 'com.zeroc:icegrid:3.6.2'
    compile 'com.zeroc:icelocatordiscovery:3.6.2'
    compile 'com.zeroc:icestorm:3.6.2'
}</span>

版本号和依赖的包都是根据报错一个一个加的，可以尝试一下
