maven - 如何使用 Asciidoctor maven 插件排除空文件夹

Question

我使用 Asciidoctor Maven 插件从 adoc 生成 HTML。不幸的是，它从 sourceDirectory 中指定的目录复制每个源目录。如何排除这些空文件夹？

<plugin>
    <groupId>org.asciidoctor</groupId>
    <artifactId>asciidoctor-maven-plugin</artifactId>
    <version>1.5.3</version>
    <executions>
        <execution>
            <id>test-id</id>
            <phase>generate-resources</phase>
            <goals>
                <goal>process-asciidoc</goal>
            </goals>
            <configuration>
                <sourceDirectory>mysourcedirectory</sourceDirectory>
                <sourceDocumentName>Test.adoc</sourceDocumentName>
                <outputDirectory>${project.build.directory}/outputdir</outputDirectory>
                <relativeBaseDir>true</relativeBaseDir>
                <preserveDirectories>true</preserveDirectories>
                <backend>html</backend>
            </configuration>
        </execution>
    </executions>
</plugin>

我的输入目录是这样的:

 ── mysourcedirectory
    ├── Test.adoc  
    └── subfolder1
        ├── doc1.adoc    
        └── doc2.adoc

asciidoc 的输出如下所示(subfolder1 为空，我希望将其排除):

 ── mysourcedirectory
    ├── Test.adoc  
    └── subfolder1

根据 Asciidoc ( https://github.com/asciidoctor/asciidoctor-maven-plugin#configuration-options ) 的文档，我可以使用 resources 标签来完成。我已经尝试过这种方式，但它不起作用:

<configuration>
    <resources>
        <resource>
            <includes>
                <include>**/*.*</include>
            </includes>
        </resource>
    </resources>
...
</configuration>

asciidoctor-maven-plugin不支持删除空目录。有 the issue 144关于这一点，并且不考虑修复它。

您可以使用 Antrun Plugin 解决这个问题和 delete empty directories在 Ascii Doctor 运行之后:

<!-- your configuration of Ascii Doctor -->
<plugin>
  <groupId>org.asciidoctor</groupId>
  <artifactId>asciidoctor-maven-plugin</artifactId>
  <version>1.5.3</version>
  <!-- rest of your config -->
</plugin>
<!-- deleting empty directories in output directory of Ascii Doctor -->
<plugin>
  <artifactId>maven-antrun-plugin</artifactId>
  <version>1.8</version>
  <executions>
    <execution>
      <id>delete-empty-dirs</id>
      <phase>generate-resources</phase>
      <goals>
        <goal>run</goal>
      </goals>
      <configuration>
        <target>
          <delete includeemptydirs="true">
            <fileset dir="${project.build.directory}/generated-docs">
              <and>
                <size value="0" />
                <type type="dir" />
              </and>
            </fileset>
          </delete>
        </target>
      </configuration>
    </execution>
  </executions>
</plugin>

要确保在 Ascii Doctor 之后调用 Antrun 插件，您可以将其声明放在 asciidoctor-maven-plugin 之后，并确保它们绑定(bind)到同一阶段。我在上面的示例中使用了 generate-resources。
