有人有类似的问题吗?如何为surefireArgLine设置值?

Did anyone have similiar problem? How to set value for surefireArgLine?

推荐答案

我遇到了同样的问题，我认为我在

I had the same problem and i think i found the solution on the vertx-issue tracker.

简而言之，您必须将IntelliJ Maven(surefire插件)集成配置为不同的行为.

In short you have to configure your IntelliJ Maven (surefire plugin) integration to behave differently.

通过以下方式执行此操作: Preferences -> Build,Execution,Deployment -> Build Tools -> Maven -> Running Tests

Do this via: Preferences -> Build,Execution,Deployment -> Build Tools -> Maven -> Running Tests

取消选中argLine

这在IntelliJ 14.1.6和mvn 3.3.9中对我有效

This works for me in IntelliJ 14.1.6 with mvn 3.3.9
