Gaelyk是一个轻量级的开发Google App Engine的Groovy开发包，如果你打算开发基于Google App Engine，你可以考虑使用Groovy和Gaelyk。本文就介绍如何在IDEA 9下开发Gaelyk应用。本文所使用到得IDEA是指IDEA 9.0 旗舰版，而不是社区版。当然我们首先肯定你已经安装好Google App Engine。
1 首先我们要下载Gaelyk的项目模板，你可以访问 http://gaelyk.appspot.com/download/ 下载，当前版本为0.3.2。下载后请执行解压。
2 打开IDEA，基于解压的目录创建一个新的项目，只需要创建普通的Java Module。
3 项目创建完毕后，我们需要设置项目的classpath，也就是dependencies。这里我们分别创建GAE，Groovy和Gaelyk，这些jar包都在war/WEB-INF/lib下，最后我们再添加一个servlet的jar，主要是方便我们编写gtpl文件。

4 接下来我们先进行一些设置，然后再进行项目设置。首先添加Google App Engine Server，打开设置面板，然后选择“Application Servers“，然后添加GAE Server即可。然后打开"File Types”选项，选择“Groovy Service Pages”，将"*.gtpl"添加为其类型，这样我们就可以再IDEA下以GSP来编辑gtpl文件啦。
5 接下来我们要为项目设置web facet。打开module，然后添加web facet，请设置正确的路径信息。接下来我们还需要在web facet下添加Google App Engine Server，如下图

6 由于我们要在IDEA下直接运行Google App Engine Server，所以我们需要设置项目的artifacts，在"project structure"面板中选择artifacts，然后进行下图设置。

7 接下来我们要在IDEA中启动Google App Engine Server。点击“tool”菜单下的“edit configurations”，然后创建一个Google App Engine Server的运行配置，如下图：

8 接下就是运行GAE Server，运行后你会看到Gaelyk标准的欢迎页面。
9 回到Google App Engine Web管理页面（http://appengine.google.com) ，创建一个新的项目，如gaelyk-xxx，创建完毕后，会到IDEA中，打开appengine-web.xml，输入app id。
10 上传Gaelyk应用。点击“tools”菜单下的“Upload App Engine Application”，如果第一次上传，会提示你输入email和密码，这样就完成了Google App Engine应用的部署。

总结：本文只是讲述了如何在IDEA 9进行Gaelyk的应用整合，还没有涉及到IDEA的强大的Groovy编辑功能，GSP的编辑功能等，还有就是Gaelyk的各种特性，相信环境搭建完毕后，你能很快进行应用开发啦。

What's New in Version 9

This release delivers many major updates to IntelliJ IDEA including better performance, support for Java EE 6 and other new frameworks, lots of productivity improvements in the editor, a more streamlined user interface and much more.

Please visit http://www.jetbrains.com/idea/whatsnew/index.html for detail!

The wait is over, ladies and gentlemen! The release build is baked, tested, and put on the shelf. Tastes good, so go and grab it now!

Let us write down a short summary of what was accomplished since the TeamCity 4.5 release.

First of all, here’s the list of most noteworthy features:

• Support for Amazon EC2: Take advantage of cloud computing with TeamCity by putting build agents on Amazon EC2 cloud with on-demand image starting and on-idle stopping.
• Issue tracker integration with JetBrains YouTrack, JIRA and Bugzilla - out of the box, plus an API for the integration plugins for other systems.
• Maven support improvements, including simplified build configuration creation from POM file, and build triggering on Maven artifacts change.
• Build configuration templates for eliminating redundancy in build configurations settings.
• Project archiving for putting no-longer-active projects out of sight.
• Command line tool for running Personal builds on server without IDE integration.
• Backup & Restore were added to simplify TeamCity maintenance. Also, migration tool was re-implemented.

Other improvements:

• Now you can view the status of a change across all build configurations on a single page.
• Failure responsibility feature has been advanced to cover not only builds, but also individual test failures.
• Various actions performed by TeamCity users are now stored in the Audit log, which can be browsed from the web UI.
• Code coverage analysis has been significantly improved for both Java (based on IntelliJ IDEA coverage engine) and .NET (support for NCover and PartCover).
• And many more

New and improved integrations:

• Git & Mercurial support are now bundled with TeamCity.
• Remote Run now works for Git from IntelliJ IDEA & Eclipse.
• New support for Cucumber, Shoulda, Test-Spec in Rake runner.
• TeamCity IntelliJ IDEA plugin now works with IntelliJ IDEA Community Edition and RubyMine 2.0.

Of course, this is not an exhaustive list, so check What’s New to get a full overview of new features and improvements.
