java - maven-surefire-plugin 包含/排除优先级

Question

当使用 maven-surefire-plugin 并同时包含和排除时，它们的处理顺序是什么？此外，如果您有 3 组测试，第一组是基本组，第二组和第三组是特殊情况，您可以使用配置文件进一步包含/排除吗？配置文件包含/排除设置将如何合并？例如，我想做这样的事情:

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.12.2</version>
        <configuration>
          <excludes>
            <exclude>/org/mycompany/dataset/test/ExtractProd*.java</exclude> <!-- requires special network connectivity -->
            <exclude>/org/mycompany/dataset/test/LargeDataset*.java</exclude> <!-- requires lengthy processing -->
          </excludes>
        </configuration>
      </plugin>
    </plugins>
  </build>

  <profiles>
    <profile>
      <id>connectedToProdNetwork</id>
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
              <includes>
                <include>/org/mycompany/dataset/test/ExtractProd*.java</include>
              </includes>
            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile>
    <profile>
      <id>runForAsLongAsYouNeed</id>
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
              <includes>
                <include>/org/mycompany/dataset/test/LargeDataset*.java</include>
              </includes>
            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile>
  </profiles>

然后就可以这样运行了:

mvn package -P connectedToProdNetwork

或

mvn package -P runForAsLongAsYouNeed

或

mvn package -P connectedToProdNetwork,runForAsLongAsYouNeed

使用 mvn help:effective-pom -P [profileA]我能够确定，如果我指定一个配置文件，则生成的有效 pom 将是:

        <configuration>
          <includes>
            <include>[includeFromProfileA]</include>
          </includes>
          <excludes>
            <exclude>/org/mycompany/dataset/test/ExtractProd*.java</exclude> <!-- requires special network connectivity -->
            <exclude>/org/mycompany/dataset/test/LargeDataset*.java</exclude> <!-- requires lengthy processing -->
          </excludes>
        </configuration>

如果我提供多个配置文件，mvn help:effective-pom -P [profileA],[profileB] :

        <configuration>
          <includes>
            <include>[includeFromProfileAOrBSeeminglyArbitraryChoice]</include>
          </includes>
          <excludes>
            <exclude>/org/mycompany/dataset/test/ExtractProd*.java</exclude> <!-- requires special network connectivity -->
            <exclude>/org/mycompany/dataset/test/LargeDataset*.java</exclude> <!-- requires lengthy processing -->
          </excludes>
        </configuration>

最后，如果我添加属性 combine.children="append" 到<includes>配置文件的元素，并提供两个配置文件，mvn help:effective-pom -P [profileA],[profileB] :

        <configuration>
          <includes combine.children="append">
            <include>[includeFromProfileA]</include>
            <include>[includeFromProfileB]</include>
          </includes>
          <excludes>
            <exclude>/org/mycompany/dataset/test/ExtractProd*.java</exclude> <!-- requires special network connectivity -->
            <exclude>/org/mycompany/dataset/test/LargeDataset*.java</exclude> <!-- requires lengthy processing -->
          </excludes>
        </configuration>

但是，现在每个文件都被指定为 <include>和 <exclude> ，会发生什么？

---- 更新 2 ----

实际使用此配置运行构建:

<configuration>
  <includes>
    <include>**/TestA.java</include>
  </includes>
  <excludes>
    <exclude>**/TestA.java</exclude>
  </excludes>
</configuration>

不是否运行 TestA，所以它显示为 <exclude>会压倒<include> . 请注意，为了完整起见，我确实颠倒了顺序并输入了 <excludes>之前 <includes>但行为并没有改变。如果有人能找到概述这种行为的源代码之外的地方，我很乐意给他们答案......

Answer 1

我找不到关于 surefire 插件的官方文档，但确实 exclude-override-include 是一种常见的方法，Maven 也将其应用于其他类似的上下文中，例如资源。

唯一的官方相关信息(我发现)来自官方 Maven POM 引用文档，here :

includes: A set of files patterns which specify the files to include as resources under that specified directory, using * as a wildcard.

excludes: The same structure as includes, but specifies which files to ignore. In conflicts between include and exclude, exclude wins.

注意:我在有趣的语句中添加了最后的粗体格式。

因此，在官方 maven 插件中很可能使用相同的方法(通常，所有插件都具有 org.apache.maven.plugins groupId 和 maven- 前缀作为 artifactId)。
