在web.xml中添加了以下内容:
<filter>
<filter-name>WroContextFilter</filter-name>
<filter-class>ro.isdc.wro.http.WroContextFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>WroContextFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>WebResourceOptimizer</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>targetBeanName</param-name>
<param-value>wroFilter</param-value>

在WEB-INF文件夹中创建了两个新文件wro.xml和wro.properties:
wro.properties:
managerFactoryClassName=ro.isdc.wro.manager.factory.ConfigurableWroManagerFactory
preProcessors=less4j,cssUrlRewriting,lessCssImport
postProcessors=less4j
disableCache=true
wro.xml:
<groups xmlns="http://www.isdc.ro/wro">
<group name="base">
<css>/resources/skins/abc/testing.less</css>
</group>
</groups>
这里'resources'是一个文件夹:src / main / webapp。
在/ resources / skins / abc / folder:
中添加了一个文件testing.less.btn-expand (@height: 30px) {
box-sizing: border-box;
height: @height;
display: inline-block;
color: #fff;
font-size: 12px;
text-decoration: none;
padding-left: 20px;
padding-right: 1px;
margin-right: 20px;
background: transparent url('images/sprites.png') no-repeat -5px -164px;
border: 0;
position: relative;
outline: none;
cursor:pointer;
overflow: visible;
}

我没有在我的eclipse IDE中安装m2e-wro4j插件。
基于以上所述,我假设当我从命令提示符[mvn clean install]进行maven构建时,应在/ resources / css / test /文件夹中创建一个名为base.css的css文件。我可以在展开的项目WAR文件中看到新文件夹'test',但它不包含base.css文件。控制台输出看起来像这样:
[INFO] Wro4j Model path: C:\workspace\{projectname}\src\main\webapp\WEB-INF\wro.xml
[INFO] targetGroups: base
[INFO] minimize: true
[INFO] ignoreMissingResources: false
[INFO] parallelProcessing: false
[INFO] destinationFolder: C:\workspace\{projectname}\target
[INFO] jsDestinationFolder: null
[INFO] cssDestinationFolder: C:\workspace\{projectname}\target\{WAR file name}\resources\css\test
[INFO] groupNameMappingFile: null
[INFO] wroManagerFactory class: ro.isdc.wro.maven.plugin.manager.factory.ConfigurableWroManagerFactory
[INFO] The following groups will be processed: [base]
[INFO] folder: C:\workspace\{projectname}\target\{WAR file name}\resources\css\test
[INFO] processing group: base.css
[INFO] folder: C:\workspace\{projectname}\target
[INFO] processing group: base.js
再观察一次。为了确保wro.properties文件被正确放置并被插件选中,我在此文件[postProcessors=less4jtttt]
中尝试了一些错误的值,并且在进行构建时可能会看到异常。但是,wro.xml文件中的无效文件路径未引发任何异常。
答案 0 :(得分:1)
虽然答案也已发布在邮件列表中,但我也会在此处发布以获取可见性:
我设法在本地重现你的测试用例,我看到的是一个空文件。第一印象是存在问题,但实际上这是预期的行为。 正在处理的内容越少,定义了一个mixin,只要它没有被使用就不会产生任何输出。
要获得有效的输出,请更新您的less以使用该mixin:
div.expandable {
.btn-expand()
}
