我想在使用maven-war-plugin构建我的WAR文件时重命名静态文件,版本号。对于intance,在我的项目中我有一个文件:
src/main/webapp/css/my.css
我希望它在WAR文件中显示为:
css/my-versionNumber.css
已经提出同样的问题(参见Rename static files on maven war build),但接受的答案是重命名目录。我不想重命名目录,我想重命名实际文件。
这可能吗?

好的,我找到了一种方法,原则来自:Automatic update of generated css files via m2e。
重命名文件
我选择使用Maven AntRun Plugin,因为它允许使用替换模式重命名多个文件,有关详细信息,请参阅https://stackoverflow.com/a/16092997/1768736。
使用替代解决方案:
maven-assembly-plugin
:但它不支持重命名文件集,只重命名单个文件(请参阅file assembly descriptor和此答案的评论:https://stackoverflow.com/a/4019057/1768736)maven-resources-plugin
:它允许复制资源,而不是重命名资源(请参阅copy resources mojo以及此问题的评论:Renaming resources in Maven)使重命名的文件可用于maven-war-plugin
复制文件:我们的想法是将重命名的文件复制到临时目录中,由maven-war-plugin
作为网络资源添加到WAR文件中。 maven-war-plugin
在packaging
阶段构建WAR,因此我们需要在此之前复制重命名的文件。
阻止maven-war-plugin
管理maven-antrun-plugin
要重命名的文件:这是通过使用参数warSourceExcludes
来完成的。
使用m2e-wtp
在Eclipse中工作更改生命周期映射:问题是m2e
默认情况下不会执行POM文件中定义的所有生命周期(要查看执行/忽略的生命周期,请从Eclipse中转到项目中)属性,然后Maven
> Lifecycle Mapping
)。因此,您需要使用假插件org.eclipse.m2e.lifecycle-mapping
添加maven-antrun-plugin
生命周期,请参阅life cycle mapping documentation。
更改maven-antrun-plugin
输出目录:问题是m2e-wtp
在启动任何生命周期之前获取其网络资源,因此,maven-antrun-plugin
之前可以重命名文件。作为一种变通方法,我们创建一个仅在项目由m2e
构建时激活的配置文件,以更改用于设置maven-antrun-plugin
输出目录的属性,直接写入m2e-wtp
网络资源。
那就是它! POM片段:

您需要定义
<properties>
<css.version>1.1.0</css.version>
</properties>
之后由EL调用它 CSS / $ {css.version}的CSS
