yuicompressor maven插件和maven-war-plugin

Question

我已经努力让这个插件很好地使用maven-war-plugin几个小时了，我想是时候寻求帮助了。我的插件定义如下：

<plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>yuicompressor-maven-plugin</artifactId>
    <version>1.3.0</version>
    <executions>
        <execution>
            <id>compressyui</id>
            <phase>process-resources</phase>
            <goals>
                <goal>compress</goal>
            </goals>
            <configuration>
                <nosuffix>true</nosuffix>
                <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
                <jswarn>false</jswarn>
            </configuration>
        </execution>
    </executions>
</plugin>

如果我删除nosuffix=true，那么我可以看到压缩/缩小的-min.js文件像预期的那样进入war，但是在这个标志打开的情况下，它们在构建war文件时会被maven-war-plugin (我假设)覆盖。我真的需要文件名保持不变...有没有人知道我需要做些什么才能使用相同的文件名，同时还能把缩小的版本放到最后的战争中去？

Answer 1

好的。我终于想通了。您需要在yuicompressor插件中定义一个<webappDirectory>，然后可以在maven-war-plugin中将其作为<resource>引用。在下面的示例中，我使用的是<directory>${project.build.directory}/min</directory>

<plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>yuicompressor-maven-plugin</artifactId>
    <version>1.3.0</version>
    <executions>
        <execution>
            <id>compressyui</id>
            <phase>process-resources</phase>
            <goals>
                <goal>compress</goal>
            </goals>
            <configuration>
                <nosuffix>true</nosuffix>
                <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
                <webappDirectory>${project.build.directory}/min</webappDirectory>
                <jswarn>false</jswarn>
            </configuration>
        </execution>
    </executions>
</plugin>
<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <executions>
        <execution>
            <id>default-war</id>
            <phase>package</phase>
            <goals>
                <goal>war</goal>
            </goals>
            <configuration>
                <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
                <encoding>UTF-8</encoding>
            </configuration>
        </execution>
    </executions>
    <configuration>
        <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
        <encoding>UTF-8</encoding>
        <webResources>
            <resource>
                <directory>${project.build.directory}/min</directory>
            </resource>
        </webResources>
    </configuration>
</plugin>

只需在WAR插件上配置'warSourceExcludes‘即可。

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <warSourceExcludes>**/*.css,**/*.js</warSourceExcludes>
    </configuration>
</plugin>

我想添加为我工作的配置：

首先，为了修复m2e抱怨的“生命周期中没有涵盖的插件执行”，我在取自this post的父pom中添加了以下内容

  <pluginManagement>
    <plugins>
        <!--This plugin's configuration is used to store Eclipse 
            m2e settings only. It has no influence on the Maven build itself. -->
        <plugin>
            <groupId>org.eclipse.m2e</groupId>
            <artifactId>lifecycle-mapping</artifactId>
            <version>1.0.0</version>
            <configuration>
                <lifecycleMappingMetadata>
                    <pluginExecutions>
                        <pluginExecution>
                            <pluginExecutionFilter>
                                <groupId>net.alchim31.maven</groupId>                               
                                <artifactId>yuicompressor-maven-plugin</artifactId>
                                <versionRange>[1.0.0,)</versionRange>
                                <goals>
                                    <goal>compress</goal>
                                </goals>
                            </pluginExecutionFilter>
                            <action>
                                <execute />
                            </action>
                        </pluginExecution>
                    </pluginExecutions>
                </lifecycleMappingMetadata>
            </configuration>
        </plugin>
    </plugins>
</pluginManagement>

然后我在战争pom中写道：

<build>
    <plugins>
        <plugin>
        <groupId>net.alchim31.maven</groupId>
        <artifactId>yuicompressor-maven-plugin</artifactId>
        <version>1.4.0</version>
        <executions>
        <execution>
            <goals>
              <goal>compress</goal>
            </goals>
            <configuration>
               <linebreakpos>300</linebreakpos>
               <excludes>
                 <exclude>**/*-min.js</exclude>
                 <exclude>**/*.min.js</exclude>
                 <exclude>**/*-min.css</exclude>
                 <exclude>**/*.min.css</exclude>
               </excludes>              
               <nosuffix>true</nosuffix>
            </configuration>
        </execution>
        </executions>
        </plugin>
        <plugin>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <warSourceExcludes>**/*.css,**/*.js</warSourceExcludes>
            </configuration>
        </plugin>
    </plugins>
</build>

这将在项目构建目标目录中生成缩小的css和js文件，同时排除原始文件。

我希望这能节省一些人的时间。
