提问by Ilya Artamonov
I have spring-bootproject with integration tests. I'm trying to move to JDK 9. After some changes in pom I'm able to build (with tests skipped) and run project on java 9. But when I try to perform integration tests, I get an exception:
我有带有集成测试的spring-boot项目。我正在尝试迁移到JDK 9。在 pom 中进行一些更改后，我可以在 java 9 上构建（跳过测试）并运行项目。但是当我尝试执行集成测试时，出现异常：

回答by Ilya Artamonov
The problem was in maven-surefire-pluginversion 2.20.1. It is not workin g for me even on JDK 8. After decreasing version to 2.18.1started to work fine.
问题出在maven-surefire-plugin版本2.20.1 中。即使在 JDK 8 上它也对我不起作用。将版本降低到2.18.1 后开始工作正常。
