Java JaCoco MVN未知块类型,java,maven,jacoco,jacoco-maven-plugin,Java,Maven,Jacoco,Jacoco Maven Plugin,因此，我使用JacoCoMaven插件自动生成代码覆盖率报告，这样我就可以将它们发送给codecov，在GitHub上显示。突然，我从JaCoco那里得到一个构建失败的消息，说“未知块类型”。这件事昨天没有发生，所以我不知道为什么现在会发生。下面是pom.xml的相关部分 <plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId

因此，我使用JacoCoMaven插件自动生成代码覆盖率报告，这样我就可以将它们发送给codecov，在GitHub上显示。突然，我从JaCoco那里得到一个构建失败的消息，说“未知块类型”。这件事昨天没有发生，所以我不知道为什么现在会发生。下面是pom.xml的相关部分

未知块类型

在执行

org.jacoco:jacococomaven插件：0.8.5:report

期间，表示已损坏

jacoco.exec

文件

该文件由JaCoCo代理在JVM终止时生成，测试使用

当带有测试的JVM被硬终止而不是成功终止时，通常会发生文件损坏

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，因为这通常表示

maven surefire plugin

等待测试终止一段时间，然后杀死JVM？请参阅类似问题

总之，请修复您的代码/测试-带有测试的JVM应该优雅地终止

我还相信我已经找到了麻烦的测试文件，因为当我排除它时，一切都正常运行，甚至停止挂起。我只是不明白该文件中会出现什么错误，从而导致挂起（没有循环，正在执行的唯一“文件”是将默认System.out/err streams修改为单独的打印写入程序），因为其中大部分是字符串操作

引用maven surefire插件版本

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，但是Maven永远看不到测试完成，构建可能会挂起

我收到了一条非常类似的消息，执行了
mvn安装
，产生了一个JaCoCo错误（区别是
未知块类型45
错误，而不是原始问题中的
未知块类型77
）：

我通过简化执行
mvn clean
并重新启动构建来消除这个错误。
我不知道答案，但看看这个线程：。@AndrewCheong只是尝试了一下，但没有成功，即使超时值非常大。我应该提到的另一件事是，甚至在我遇到这个问题之前，我的mvn在完成最后一个测试后挂起了相当长的一段时间，似乎什么都没有做。您可以执行与-X一起使用的maven命令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某个文件有关？您正在运行什么java版本？请发布错误堆栈跟踪以了解更多信息insight@wemu在测试完成后，编辑我的帖子以插入-X跟踪。该项目使用Java1.8，所以可能是一个愚蠢的问题，但我对这方面还不熟悉，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，并且所有内容都会在完成后立即终止。因此，我实际上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。@user13403586首先-如果没有错误，人们怎么能盲目地猜测代码中的错误？尽管如此，根据您的其他评论，我还是看到了更新的答案。因此，我将测试更改为不再设置System.out，而只是将PrintWriter传递给打印的方法，但我现在得到了一个“EOFEException”。我确保关闭所有的流。我更想问的是，什么样的一般情况可能会导致这种情况发生？啊，没关系，我找到了解决办法。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该扫描仪，但在测试结束时关闭了扫描仪。一旦我删除了关闭语句，它就不再挂起，问题就消失了。谢谢你的帮助！
