IntelliJ社区版本2018.2无法导入maven项目:有关详细信息，请参阅日志

Question

我在Mojave上使用IntelliJ，并在IDE中加载maven项目时出现问题

• 我将IntelliJ更新为最新版本，即2018.2社区版。
• 将JDK更新为11.0.1
• 更新maven至3.5.4

现在，我无法在IDE中看到maven项目，而且我的IDE一直在事件日志窗口中显示“无法导入”错误。奇怪的是，我可以使用终端上的mvn命令编译项目，但是在IDE窗口中看不到maven项目。

错误屏幕截图

我还试着检查它下面的日志。我已经确保了IntelliJ使用的Java版本是版本11。

Answer 1

最后，我设法通过卸载IntelliJ，删除当前和以前版本的IntelliJ (⁨User⁩/⁨/⁨⁩/⁨/⁨Library⁩/⁨Preferences⁩)中的所有设置，然后重新安装它来解决这个问题。

在此之前，我尝试了以下所有的建议，在不同的帖子，但对我的情况没有多大帮助。

• 清理.idea文件夹
• 正确设置路径变量
• 使用maven从已安装的目录，而不是绑定选项

最重要的部分是清理旧的设置，一个简单的重新安装对我来说是行不通的。

我仍然不确定是什么导致了那些设置中的“无效选项-d64”错误。但现在我终于可以试用最新的Java、Maven和IntelliJ了

谢谢。

Answer 2

JDK 10/11的一个已知问题是：https://youtrack.jetbrains.com/issue/IDEA-195143。错误在2018.3被修复。

Answer 3

您运行Maven时似乎使用了一个无法识别的选项-d64，这导致了错误。检查IntelliJ中的Maven设置。
