我使用user-data命令运行了一个Maven mvn clean install -Denv="test" -Ddb="h2"项目集成测试，它们似乎都通过了，只是我收到了一些崩溃的测试消息：The forked VM terminated without properly saying goodbye. VM crash or System.exit called?
另一个项目user-rest也是上述项目的客户端，也会显示相同的错误。那使我认为这可能与项目无关。

更新：从属user-rest项目中仍然存在相同的问题，该项目包含对固定user-data项目的依赖性。我尝试添加相同的插件，但没有帮助。它有一个dumpstream文件，其中包含：Error: Could not find or load main class org.apache.maven.surefire.booter.ForkedBooter

我在一个项目中面临着同样的问题。我通过升级到surefire插件的最新版本并通过讨论https://github.com/carlossg/docker-maven/issues/90
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M3</version>
<configuration>
<useSystemClassLoader>false</useSystemClassLoader>
</configuration>
</plugin>
答案 1 :(得分：0)
解决方案是使用以下属性：
<forkedProcessExitTimeoutInSeconds>120</forkedProcessExitTimeoutInSeconds>
实际上，测试是如此之久，以至于叉车将超时。
