分叉的VM在没有正确地说再见的情况下终止。VM崩溃或System.Exit调用？

Question

我已经配置了maven-surefire-plugin和jacoco插件来生成junit代码覆盖率报告。然而，我在两个不同的场景中得到了两个不同的错误。你能看看下面的错误并帮助我吗？任何帮助都是值得赞赏的。

当我在maven-surefire-plugin配置中将forkCount保持为0（零）时，所有测试都会成功执行，但不会生成jacoco报告。它给我的消息是“由于缺少执行数据文件，跳过JaCoCo执行”。

Answer 1

您必须在使用Java10时升级jacoco版本。您可以使用JaCoCo Version0.8.3，它似乎可以解决这个问题。
