Eclipse EASE Javascript-HelloWorld

Question

嗨，我正计划创建一个脚本程序来扫描我的Eclipse Java Elements-类/接口，并且需要在编译之前生成一些报告。在网络中搜索时，我发现了这个新的Eclipse EASE概念。但是，我已经在Eclipse中下载了必需的插件。

仍然无法运行示例Hello World Application程序。

我创建了一个新文件-“ hello.js”，它仅包含一个语句 print（“ Hello World”）

当我尝试运行方式-EASE脚本时，出现以下错误：

确保已从更新站点http://download.eclipse.org/ease/update/release安装了EASE Core和EASE Javascript Support (Incubation)。

然后确保已加载Environment模块，该模块提供了print()方法。 通常，此模块应自动加载，但您也可以手动加载：

new Packages.org.eclipse.ease.modules.EnvironmentModule().loadModule("/System/Environment", false);

print("hello, world")
