Maven Replacer插件，正则表达式无法正常工作 [英] Maven replacer plugin, regex no working

问题描述

我正在与Maven进行项目合作，并使用maven-replacer-plugin将我的所有CSS/javascript文件替换为缩小版本.

I'm working on a project with Maven and using the maven-replacer-plugin to replace all my css/javascript files for the minified version.

我要替换这个:

<!-- JSMIN js/script.min.js -->
    <script src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
    <script src="js/jquery.placeholder.min.js"></script>
    <script src="js/smoothscroll.js" async=""></script>
    <script src="js/javascript.js"></script>
    <script src="js/swfobject.js"></script>
    <script src="js/player.js"></script>
<!-- END JSMIN -->

与此:

<script src="js/script.js"></script>

类似于CSS.

插件说它已将正则表达式应用于我的4个html文件，这是正确的，但我看不到这些文件上的更改.

The plugin says that it has applied the regex to my 4 html files which is correct but i see no changes on those files.

这是插件的配置

<plugin>
    <groupId>com.google.code.maven-replacer-plugin</groupId>
    <artifactId>maven-replacer-plugin</artifactId>
    <executions>
        <execution>
            <phase>prepare-package</phase>
            <goals>
                <goal>replace</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <basedir>${project.basedir}/src/main/webapp/</basedir>
        <outputDir>test</outputDir>
        <includes>
            <include>**/*.html</include>
        </includes>
        <regexFlags>
            <regexFlag>CASE_INSENSITIVE</regexFlag>
            <regexFlag>MULTILINE</regexFlag>
            <regexFlag>DOTALL</regexFlag>
        </regexFlags>
        <replacements>
            <replacement>
                <token>&lt;!-- JSMIN (.*) --&gt;(.*?(\r))+.*?&lt;!-- END JSMIN --&gt;</token>
                <value>&lt;script src="$1"&gt;&lt;/script&gt;</value>
            </replacement>
            <replacement>
                <token>&lt;!-- CSSMIN (.*) --&gt;(.*?(\r))+.*?&lt;!-- END CSSMIN --&gt;</token>
                <value>&lt;link href="$1" rel="stylesheet" type="text/css"/&gt;</value>
            </replacement>
        </replacements>
    </configuration>
</plugin>

正则表达式对我和我的同事来说似乎是正确的...有什么帮助吗? 预先感谢

The regex seems correct to me and my co-workers...any help? Thanks in advance

在将替换文件打包到战争中之前，需要有一个挂钩来运行这些文件上的替换文件.如果两者都在同一阶段执行(即prepare-package)，请确保将其添加到maven-replacer-plugin之前.确保使用2.0.1或更低版本的war插件，因为常用的2.1.0+会复制资源两次，从而覆盖替换资源.使用以下war插件配置，可以在打包文件之前对其进行修改.

There needs to be a hooking spot for running replacements on files before they are packaged into a war. Make sure you add this before the maven-replacer-plugin if they both execute in the same phase (i.e. prepare-package). Make sure you use version 2.0.1 or below of the war plugin since the commonly used 2.1.0+ copies resources twice which overrides replacements. Use the following war plugin configuration to allow the files to be modified before being packaged.
