ras*_*orp 14 java eclipse vaadin maven vaadin7
我是Vaadin框架的新手,我看起来非常有趣,使用eclipse和maven来开发和构建我的应用程序我觉得很烦人每次我做一个mvn干净安装它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Button,也会在构建应用程序时花费太多.
我已经研究了一段时间在互联网和2本书,但找不到足够的信息,如何使它只编译我正在使用的组件,而不是整套.
我使用maven原型创建了项目:
mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7.1.9
我确信每次构建战争时都会编译widgetset,当我执行mvn clean时会删除目录:/ src/main/webapp/VAADIN/widgetsets和/ src/main/webapp/VAADIN/gwt-unitCache
当我运行mvn install时,构建将持续超过3分钟:

在此之后,再次生成包含以下目录的目录/ src/main/webapp/VAADIN/widgetsets:
WEB-INF
com.my.example.AppWidgetSet
它还生成/ src/main/webapp/VAADIN/gwt-unitCache

您需要自定义widgetset吗？如果您没有使用任何小部件插件,并且因为您是Vaadin的新用户,我假设您还没有创建自己的小部件(？),您可以简单地使用Vaadin提供的预编译小部件集.为此,请从项目中删除任何xxx.gwt.xml文件,并使用com.vaadin.DefaultWidgetset替换web.xml中对它的引用.
web.xml中:
<init-param>
<name>widgetset</name>
<value>com.vaadin.DefaultWidgetSet</value>
</init-param>
pom.xml中:
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-client-compiled</artifactId>
<version>7.1.9</version> <!-- or whatever version you're using -->
</dependency>
如果你确实需要一个自定义的widgetset(如果你现在不需要,那么你可能需要更进一步),帮自己一个忙,把它放在一个单独的项目中.根据我的经验,一个widgetset很少变化,所以为什么要将它包含在一个不断变化的项目中.由Vaadin提供的上述默认widgetset是构建一个的完美蓝图.只需构建自己的,并从vaadin-client-compiled.jar复制其结构.你可以使用你最喜欢的maven build helper,我的是程序集.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你在下面看到的.

构建它,使用jar作为项目中的依赖项,然后就完成了.这将永久地让你摆脱GWT称之为"widgetset编译"的巨大痛苦.
