Question

我正在使用Maven 3.3.3。我有一个包含大量静态资产的WAR项目。经常在构建我的WAR项目时（使用“mvn clean install”），即使只有Java文件发生了变化，项目也需要花费15分钟来构建。下面是我的WAR插件配置。有没有办法加快文件的构建？我正在使用“in = place”和“useCache”选项，但无济于事......

                                            <configuration>
                                                    <useCache>true</useCache>
                                                    <workDirectory>${user.home}/${project.artifactId}/war/work</workDirectory>
                                            </configuration>
                                            <executions>
                                                    <execution>
                                                            <id>default-war</id>
                                                            <phase>verify</phase>
                                                    </execution> 
                                                    <execution>
                                                            <id>war-inplace</id>
                                                            <phase>package</phase>
                                                            <goals>
                                                                    <goal>inplace</goal>
                                                            </goals>
                                                    </execution>
                                            </executions>
                                    </plugin>

这是Maven WAR插件的输出，如果这可以让我们深入了解如何加快速度

Answer 1

假设您的${user.home}位于本地磁盘上，您可以执行以下操作：

在构建为JAR的模块中加载资源。从中获取并从JAR中提供这些资源。如果您碰巧使用Spring Framework，则可以免费使用，也可以使用META-INF/resources使用Tomcat 7+。
前段时间，一位Maven提交者宣传了一个highly-concurrent version of the Plexus Archiver，用于与Maven一起构建WAR文件。你可以试试这个。

Answer 2

在我的项目中，我有大约1200个Java类。配置

的包装时间更长

<attachClasses>true</attachClasses>
<archiveClasses>true</archiveClasses>

我的直觉告诉我应该没有区别。但是包装阶段的时间更好（37对17秒）

如何加快Maven 3.3.3中WAR项目的打包速度？
