问题描述
我对Vaadin框架很新，我看起来非常有趣，使用eclipse和maven开发和构建我的应用程序我觉得很烦人，每次我做一个mvn干净的安装，将需要很长时间来构建应用程序，我发现这是因为它编译了整套小部件。即使我只在我的布局中使用了一个Button，它将在构建应用程序上花费太多的时间。
我已经在互联网和2本书中进行了一段时间的研究，但是找不到足够的信息，如何使它只能编译我正在使用的组件，而不是整个集
我使用maven原型创建了该项目：
mvn archetype：generate -DarchetypeGroupId = com.vaadin -DarchetypeArtifactId = vaadin-archetype-application -DarchetypeVersion = 7.1.9
我确定，每当我建立战争时，widgetset正在编译，当我做一个mvn清理它删除目录：/ src / mai n / webapp / VAADIN / widgetsets和/ src / main / webapp / VAADIN / gwt-unitCache
当我运行mvn安装时，构建将持续超过3分钟：

此后，再次生成目录/ src / main / webapp / VAADIN / widgetsets，包含以下目录：
WEB-INF
com.my.example.AppWidgetSet
它还生成/ src / main / webapp / VAADIN / gwt-unitCache
你需要一个自定义的widgetset吗？如果您没有使用任何插件插件，并且由于您是Vaadin的新功能，我假设您尚未创建自己的小部件（？），您可以使用Vaadin提供的预编译的widgetset。为此，从项目中删除任何xxx.gwt.xml文件，并使用com.vaadin.DefaultWidgetset替换web.xml中的引用。
web。 xml：
< init-param>
< name> widgetset< / name>
< value> com.vaadin.DefaultWidgetSet< / value>
< / init-param>
pom.xml：
<依赖性>
< groupId> com.vaadin< / groupId>
< artifactId> vaadin-client-compiled< / artifactId>
< version> 7.1.9< / version> <！ - 或您使用的任何版本 - >
< / dependency>
如果你需要一个自定义的widgetset（如果你现在没有，那么你会有机会需要一个进一步的道路），自己一个忙，把它放在一个单独的项目。在我的经验中，一个小工具很少有变化，所以为什么要把它包含在一个不断变化的项目中。 Vaadin提供的上述默认的widgetset是建立一个的完美蓝图。只需建立自己的，并从vaadin-client-compile.jar复制其结构。你可以使用你最喜欢的maven构建帮助器，我的是汇编。只需创建一个maven项目，设置pom.xml，添加一个xxx.gwt.xml，并确保web.xml包含对它的引用。我自己的设置看起来像下面你看到的。

Build它使用jar作为项目的依赖，你完成了。这将永久释放您从GWT称为widgetset编译的大痛苦。
I am new to the Vaadin framework which I looks very interesting, using eclipse and maven to develop and build my application I find pretty annoying that every time I do a mvn clean install it will take so long time to build the app, I found that this is because it compiles the whole set of widgets.
Even if I am only using a Button in my layout it will take so much on building the app.
I have researched for some time in the Internet and 2 books but cannot find enough information about how to make it to only compile components that I am using and not the whole set.
I created the project by using the maven archetype:
mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7.1.9
I am sure that the widgetset is being compiled every time I build the war, when I do a mvn clean it removes the directory: /src/main/webapp/VAADIN/widgetsets and /src/main/webapp/VAADIN/gwt-unitCache
When I run mvn install the build will last for more than 3 minutes:

After this the directory /src/main/webapp/VAADIN/widgetsets is generated again containing the following directories:
WEB-INF
com.my.example.AppWidgetSet
It also generates /src/main/webapp/VAADIN/gwt-unitCache
Do you need a custom widgetset? If you're not using any widget addons, and since your're new to Vaadin I am assuming that you did not create your own widgets yet(?), you can simply use the precompiled widgetset provided by Vaadin. To do this, remove any xxx.gwt.xml file from your project, and replace the reference to it in web.xml with com.vaadin.DefaultWidgetset.
web.xml:
<init-param>
<name>widgetset</name>
<value>com.vaadin.DefaultWidgetSet</value>
</init-param>
pom.xml:
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-client-compiled</artifactId>
<version>7.1.9</version> <!-- or whatever version you're using -->
</dependency>
If you do need a custom widgetset (and if you don't now, chances are that you will need one further down the road), do yourself a favor and put it in a separate project. In my experience, a widgetset very seldom changes, so why include it in a project that constantly changes. The default widgetset mentioned above, provided by Vaadin, is the prefect blueprint for building one. Just build your own, and copy its structure from vaadin-client-compiled.jar. You can use your favourite maven build helper for that, mine is assembly. Just create a maven project, setup pom.xml, add a xxx.gwt.xml and make sure web.xml contains a reference to it. My own setup looks something like what you see below.

Build it, use the jar as a dependency in your project, and you're done. This will permanently release you from the big pain-in-the-butt that GWT calls "widgetset compilation".
