如何更改 Maven 2 / Cobertura 工具目标的默认输出？

发布于 2024-08-17 04:29:43 字数 220 浏览 13 评论 0原文

当我使用 Maven 2 使用命令来检测我的类时

mvn cobertura：仪器

输出（检测的类）放在 \target\ generated-classes 中。有没有办法将输出位置更改为\target\classes？

我检查了 cobertura-maven 插件的检测任务，但这到目前为止还没有给我一个解决方案。

您还没有说明为什么要覆盖默认位置，但我认为您可以使用其他项目中的检测类，或者将它们包含在 Web 存档或类似的内容中。

我将以下内容添加到我的 pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <executions>
        <execution>
            <id>instrumented-classes</id>
            <goals>
                <goal>jar</goal>
            </goals>
            <phase>package</phase>
            <configuration>
                <classifier>instrumented</classifier>
                <classesDirectory>${project.build.directory}/generated-classes/cobertura</classesDirectory>
            </configuration>
         </execution>
    </executions>
</plugin>

这使得 maven 生成一个名为 projectname-instrumented.jar 的附加 jar 文件

然后可以使用

<depends>
    <group>mygroup</group>
    <project>projectname</project>
    <version>1</version>
    <classifier>instrumented</classifier>
</depends>

我没有测试的任何其他 pom（包括例如 Web 模块）依赖此 jar 文件这 100% 但过去使用过类似的机制

You have not said why you want to overwrite the default location, but I assume it is so that you can use the instrumented classes from another project, or perhaps include them in a web archive or something similar.

I added the following to my pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <executions>
        <execution>
            <id>instrumented-classes</id>
            <goals>
                <goal>jar</goal>
            </goals>
            <phase>package</phase>
            <configuration>
                <classifier>instrumented</classifier>
                <classesDirectory>${project.build.directory}/generated-classes/cobertura</classesDirectory>
            </configuration>
         </execution>
    </executions>
</plugin>

This makes maven generate an additional jar file called projectname-instrumented.jar

It is then possible to depend on this jar file from any other pom (including for example a web module) using

<depends>
    <group>mygroup</group>
    <project>projectname</project>
    <version>1</version>
    <classifier>instrumented</classifier>
</depends>

I did not test this 100% but have used similar mechanisms in the past

据我了解，cobertura 仅需要仪器类来生成报告。如果您在target/classes中创建它们，它们将覆盖原始的类文件。

如果您需要 jar 中的检测文件，您可以配置 maven-jar-plugin 来从 target/ generated-classes 目录中获取文件标准 ${build.project.outputDirectory} 中的文件或除此之外的文件。

编辑

看看 maven-jar -插件描述。要仅使用 target/ generated-classes，您的 POM 中的以下添加应该可以工作 - 尝试并根据您的需要进行修改：

<project>
  ...
  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.3</version> <!-- replace with correct version nbr! -->
        <configuration>
          <includes>
            <include>${project.build.directory}/generated-classes/**/*.class</include>
          </includes>
          <excludes>
            <exclude>${project.build.directory}/classes/**/*.class</include>
          </excludes>

        </configuration>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

${project.build.directory} 点到您的目标文件夹，${project.build.ouputDirectory} 到 target/classes。我不知道您是否可以简单地将 ${project.build.ouputDirectory} 设置为新值 - 看看 maven book的这一章，也许你会发现一些提示

或者或者另外，您可以在 coberture:instrument 完成后使用 maven 将文件从 target/ generated-classes 复制到 target/classes 。这个问题有一个答案和一个例子POM（片段），您只需要确定正确的阶段（流程资源对于您的情况来说肯定太早了）

As far as I understand, the instrumented classes are only needed by cobertura for report generation. If you create them in target/classes, they will overwrite the original class files.

If you need the instrumented files in a jar as a result, you can configure the maven-jar-plugin to pick up the files from the target/generated-classes directory instead of or in addition to the files from the standard ${build.project.outputDirectory}.

Edit

Have a look at the maven-jar-plugin description. To only use target/generated-classes, the following addition to your POM should work - try it and modify it to your needs:

<project>
  ...
  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.3</version> <!-- replace with correct version nbr! -->
        <configuration>
          <includes>
            <include>${project.build.directory}/generated-classes/**/*.class</include>
          </includes>
          <excludes>
            <exclude>${project.build.directory}/classes/**/*.class</include>
          </excludes>

        </configuration>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

${project.build.directory} points to your target folder, ${project.build.ouputDirectory} to target/classes. I do not know if you can simply set ${project.build.ouputDirectory} to a new value - have a look at the this chapter of the maven book, maybe you find some hints

Edit 2

Alternativly or additionally you can use maven to copy the files from target/generated-classes to target/classes after coberture:instrument has finished. This question has one answer with an example POM (fragment), you just have to identify the correct phase (process-resources is definitely too early for your case)
