Maven原型：js文件中的问题：“合并速度模板时出错：遇到...”

Question

尝试从我的Maven原型生成项目时遇到问题。当没有解析javascript文件时，一切都很好（即，排除在archetype-metadata.xml文件之外）。但是我需要${MyProject}在一些js文件中插入变量，以免排除项目js文件。

这是我的原型配置：（archetype-metadata.xml文件）

<!-- Project Web Content -->
<fileSet filtered="true" packaged="false" encoding="UTF-8">
    <directory>src/main/webapp</directory>
    <excludes>
        <exclude>js/libs/**/*</exclude>
        <exclude>js/angular-mock/**/*</exclude>
        <exclude>template/**/*</exclude>
        <exclude>views/**/*</exclude>
        <exclude>img/**/*</exclude>
        <exclude>font/**/*</exclude>
        <exclude>icones/**/*</exclude>
        <exclude>css/**/*</exclude>     
    </excludes>
</fileSet>

这是我在3个测试用例中遇到的不同错误（我尝试排除在archetype-metadata.xml某些出现错误的文件中）：

任何的想法 ？谢谢

我发现了问题，我与$js文件中的字符发生冲突：解析器将$变量用于变量（例如$ {rootArtifactId}）。解决方案是定义您自己的变量${dollar}：

#set( $dollar = '$' )

例如： $scope.$watch(...)必须替换为${dollar}scope.${dollar}watch(...)

该#字符必须使用相同的技巧。
