java - 使用程序集排除 *.war 文件中的属性文件

Question

我有一个 WAR 文件，它作为依赖项包含在我的汇编模块中。 WAR 文件包含一些属性，我想在新生成的 WAR 文件中排除这些属性。

由于未知原因，排除不起作用。即使我使用 **/*.properties 排除所有属性文件，这些文件也不会被排除。知道这里出了什么问题吗？

Answer 1

问题是 you're not using the right <exclude> configuration .

通过指定 <exclude>在 <dependencySet> 水平，

<dependencySet>
  <outputDirectory>/</outputDirectory>
  <unpack>true</unpack>
  <excludes>
    <exclude>WEB-INF/classes/commonDashboard.dev.properties</exclude>
    <!-- more excludes -->
  </excludes>
</dependencySet>

您正在指定应在此集合中排除的依赖项。也就是说，这里指定了不应该解压到根文件夹的依赖项。显然，因为没有 WEB-INF/classes/...依赖关系，它不匹配并且执行任何操作。事实上，它会发出警告，您可以在日志中看到:

[WARNING] The following patterns were never triggered in this artifact exclusion filter:
o  'WEB-INF/classes/commonDashboard.dev.properties'
o  'WEB-INF/classes/commonDashboard.test.properties'
o  'WEB-INF/classes/db.dev.properties'
o  'WEB-INF/classes/db.test.properties'

您想要的是排除已解压的依赖项中的文件。为此，您需要使用 <unpackOptions> 元素，其中包含排除配置:

Specifies options for including/excluding/filtering items extracted from an archive. (Since 2.2-beta-1)

因此，您应该:

<dependencySets>
  <dependencySet>
    <outputDirectory>/</outputDirectory>
    <unpack>true</unpack>
    <unpackOptions>
      <excludes>
        <exclude>WEB-INF/classes/commonDashboard.dev.properties</exclude>
        <exclude>WEB-INF/classes/commonDashboard.test.properties</exclude>
        <exclude>WEB-INF/classes/db.dev.properties</exclude>
        <exclude>WEB-INF/classes/db.test.properties</exclude>
      </excludes>
    </unpackOptions>
  </dependencySet>
</dependencySets>

这将在解压每个依赖项期间正确排除选定的文件，并且生成的程序集将不包含它们。请注意，您可以 use a regular expression而不是指定每个文件；例如:

<exclude>%regex[WEB-INF\/classes\/(commonDashboard|db)\.(dev|test)\.properties]</exclude>
