JaCoco MVN 未知块类型

【问题标题】：JaCoco MVN unknown block typeJaCoco MVN 未知块类型
【发布时间】：2020-08-08 20:17:07
【问题描述】：

所以我使用 JaCoco maven 插件自动生成代码覆盖率报告，然后我可以将它们发送到 codecov 以显示在 GitHub 上。突然间，我收到 JaCoco 的构建失败，说“未知块类型”。这不是昨天发生的，所以我不知道为什么现在会发生。这是我的 pom.xml 的相关部分

<plugin>
  <groupId>org.jacoco</groupId>
  <artifactId>jacoco-maven-plugin</artifactId>
  <version>0.8.5</version>
  <executions>
    <execution>
      <goals>
        <goal>prepare-agent</goal>
      </goals>
    </execution>
    <execution>
      <id>report</id>
      <phase>test</phase>
      <goals>
        <goal>report</goal>
      </goals>
    </execution>
  </executions>
</plugin>

如何解决此问题以正确生成覆盖率报告？

【问题讨论】：

  • 我不知道答案，但看看这个帖子：stackoverflow.com/questions/12269558/maven-jacoco-plugin-error。
  • @AndrewCheong 刚刚尝试过，但没有运气，即使超时值非常大。我应该提到的另一件事是，即使在我遇到这个问题之前，我的 mvn 在完成最后一次测试后就挂了很长一段时间，并且似乎没有做任何事情。
  • 你可以执行你正在使用的maven命令和-X来查看更多的日志输出吗？来自 jacoco 的错误消息与它试图解析一些文件有关吗？你运行的是什么java版本？
  • 请同时发布您的错误堆栈跟踪以获取更多信息
  • @wemu 编辑了我的帖子以在测试完成后包含 -X 跟踪。项目使用java 1.8

【解决方案1】：

未知的方块类型

org.jacoco:jacoco-maven-plugin:0.8.5:report 执行期间表明jacoco.exec 文件已损坏。

此文件由 JaCoCo 代理在 JVM 终止时生成，并使用 JVM shutdown hook 进行测试。

文件损坏通常发生在带有测试的 JVM 被硬杀死而不是适当的优雅成功终止时。

我的 mvn 在完成最后一次测试后挂了很长一段时间，似乎什么也没做

IMO 是否确认带有测试的 JVM 没有正常终止，因为这通常表明 maven-surefire-plugin 等待您的测试终止一段时间然后杀死 JVM - 请参阅类似问题 https://github.com/jacoco/jacoco/issues/1042

总而言之，请修复您的代码/测试 - 带有测试的 JVM 应该正常终止。

我也相信我已经找到了麻烦的测试文件，因为当我排除它时，一切运行正常，甚至停止挂起。我只是不明白该文件中有什么问题会导致挂起（没有循环，唯一正在完成的“文件”是将默认的 System.out/err 流修改为单独的打印写入器），因为大多数其中一个是字符串操作。

引用http://maven.apache.org/surefire/maven-surefire-plugin/faq.html 为maven-surefire-plugin 版本3.0.0-M4：

如果您通过 System.setOut 覆盖 Java 流，情况会更糟，因为该流也应该被破坏，但 Maven 将永远不会看到测试完成并且 构建可能会挂起。

【讨论】：

  • 这可能是个愚蠢的问题，但我是新手，如何确保我的测试正常终止？当我在 Eclipse 中运行它们时，我没有任何问题，并且一切都在完成后立即终止。
  • 所以我实际上已经缩小了导致问题的测试文件的范围，但我不明白是什么导致了该文件中的问题，因为我在 eclipse 中看不到问题。跨度>
  • @user13403586 首先 - 在没有 stackoverflow.com/help/minimal-reproducible-example 的情况下，有人怎么能盲目地猜测你的代码有什么问题？尽管如此，请根据您的其他 cmets 查看更新的答案。
  • 所以我已经将测试更改为不再设置 System.out，而是将 PrintWriter 传递给打印的方法，但我现在得到一个“EOFException”。我确保关闭所有流。我只是在问什么一般情况可能会导致我要注意这些情况？
  • 啊，没关系，我找到了解决方案。我有一个从 System.in 读取的扫描仪，尽管我在测试中从未使用过此扫描仪，但我确实在测试结束时关闭了扫描仪。一旦我删除了该关闭语句，它就不再挂起，问题就消失了。感谢您的所有帮助！
【解决方案2】：

我收到了非常相似的消息，执行 mvn install 产生 JaCoCo 错误（区别是 Unknown block type 45 错误而不是 Unknown block type 77 就像原来的问题一样）：

[ERROR] Failed to execute goal org.jacoco:jacoco-maven-plugin:0.8.5:report (report) on project UMLEditor: An error has occurred in JaCoCo report generation.: Error while creating report: Unknown block type 45. -> [Help 1]

我通过简化执行mvn clean 并重新启动构建来消除此错误。

【讨论】：

  • 这也为我解决了这个问题。谢谢！
