如何使用maven从打包的webapp中排除类 [英] How to exclude classes from a packaged webapp with maven

问题描述

如何过滤/ target / [webapp] / WEB-INF / classes中的/ target / classes中的某些类？我希望它们编译成/ target / classes /但不会在最后的战争中。

How can I filter certain classes in /target/classes from going into /target/[webapp]/WEB-INF/classes? I want them compiled into /target/classes/ but not in the final war.

推荐答案

这些类是什么？如果它们用于测试，您可以在src / test / java中指定它们，然后在测试 - 编译阶段将它们编译为目标/测试类，但不会包含在最终的战争中。

What are these classes for? If they are for testing, you can specify them in src/test/java, they will then be compiled into target/test-classes in the test-compile phase, but won't be included in the final war.

如果它们不是用于测试而且不包括在战争中，也许它们应该被重构为另一个项目，因此你可以将它指定为依赖项（也许是提供 范围，因此它们不会被部署。

If they aren't for testing and aren't to be included in the war, perhaps they should be refactored into another project so you can specify it as a dependency (perhaps with "provided" scope so they won't be deployed.

作为参考，您可以配置战争以在打包时包含和排除资源。

For reference you can configure the war to include and exclude resources when packaging.

以下示例将包含所有jpgs但从image2子文件夹中排除资源：

The following example will include all jpgs but exclude resources from the image2 sub folder:

    <configuration>
      <webResources>
        <resource>
          <!-- this is relative to the pom.xml directory -->
          <directory>resource2</directory>
          <!-- the list has a default value of ** -->
          <includes>
            <include>**/*.jpg</include>
          <includes>
          <excludes>
            <exclude>**/image2</exclude>
          </excludes>
        </resource>
      </webResources>
    </configuration>
