java - 构建 Maven 项目时测试崩溃

Question

我运行 Maven user-data项目集成测试，使用mvn clean install -Denv="test" -Ddb="h2"命令，它们似乎都很好地通过了，除了我收到一些崩溃的测试并显示消息:The forked VM terminated without properly saying goodbye. VM crash or System.exit called?另一个项目也出现同样的错误 user-rest这是上面一个的客户端。这让我认为这可能与项目无关。

完整的输出控制台日志显示:

我在以下JAVA版本下尝试过:

12.0.2-open
11.0.6-open
13.0.2.j9-adpt
13.0.2.hs-adpt

总是得到同样的错误。

更新:崩溃的集成测试如果仅运行该测试则不会崩溃。 mvn clean install -Denv="test" -Ddb="h2" -Dtest=UserServiceTest命令显示:

更新:依赖项 user-rest 中仍然存在同样的问题项目，包含对固定 user-data 的依赖项目。我尝试添加相同的插件，但没有帮助。它有一个 dumpstream文件包含:Error: Could not find or load main class org.apache.maven.surefire.booter.ForkedBooter

Answer 1

解决方案是使用以下属性:

<forkedProcessExitTimeoutInSeconds>120</forkedProcessExitTimeoutInSeconds>

事实上，测试时间太长， fork 中可能会出现超时。
