为什么是wro4j找不到我的主.更少的文件

Question

我正在使用wro4j-maven-plugin (version 1.8.0)来构建我的web资源:

          <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

                        <!-- Serves *only* to filter the wro.xml so it can get an absolute 
                            path for the project -->

My wrong .xml是这样的:

<groups xmlns="http://www.isdc.ro/wro">
<group name="angular-bootstrap">
    <css>webjar:bootstrap/3.3.6/less/bootstrap.less</css>
    <css>webjar:fontawesome/4.5.0/less/font-awesome.less</css>
    <css>file:${project.basedir}/src/main/wro/main.less</css>
    <js>webjar:jquery/2.2.3/jquery.js</js>
    <js>webjar:bootstrap/3.3.6/js/bootstrap.js</js>     
    <js>webjar:angularjs/1.5.5/angular.js</js>
    <js>webjar:angular-resource/1.5.5/angular-resource.js</js>
    <js>webjar:angular-ui-router/0.2.18/angular-ui-router.js</js>
    <js>webjar:angular-ui-bootstrap/1.3.2/ui-bootstrap.js</js>
    <js>webjar:angular-ui-bootstrap/1.3.2/ui-bootstrap-tpls.js</js>
    <js>webjar:URI.js/1.14.1/URI.js</js>        
</group></groups>

这是我的错误。属性文件:

= lessCssImport

的预处理器后处理程序= less4j,一debug = true

当我运行mvn clean install时，我得到以下错误:

Answer 1

尝试在执行Maven目标窗口中执行mvn generate-resources命令。它帮助使用Wro4J从Less生成CSS文件，至少在IntelliJ中是这样。

Answer 2

${项目。Basedir}占位符不会被maven替换，因此wro4j会使用以下路径"${project.basedir}/src/main/wro/main"从字面上搜索资源。

用户servlet上下文相对资源、类路径资源、webjar资源或绝对路径资源
