如何使用 Maven 从 WEB-INF 类文件夹中删除 etc 文件夹？

Question

我们有一个非常古老的 ant 项目，我们正在将其转换为 maven。在旧项目中，我们确实有 etc 文件夹，其中包含一些属性和一些其他部署所需的文件。我的要求是从 etc 文件夹中复制基于不同配置文件的所有必需文件，但 WEB-INF->classes 文件夹不应包含 etc 文件夹。我们项目的 pom.xml （不是整个粘贴）在下面，但是那个 etc 文件夹没有被删除：

Answer 1

正在复制 etc 目录，因为它位于默认资源目录下。

您正在根据您的需要使用目标copy-resources 复制资源，这很棒。但是默认的resources 目标也会同时自动执行，这就是为什么您会在类下看到 etc 文件夹。

在这种情况下，我会做的一件事是从默认资源目录中排除所有目录和文件，这样只要resources 目标自动运行，就不会复制任何内容。

例如，

<project>
  ...
  <build>
    ...
    <resources>
      <resource>
      <directory>src/resources</directory>     
      <excludes>
          <exclude>**</exclude>
        </excludes>
      </resource>
      ...
    </resources>
    ...
  </build>
  ...
</project>
