Question

我的项目一直运行良好，直到我今天在intelIj中打开它并尝试运行它，但出现此错误

Error:maven-annotations-test:myapp: java.lang.IllegalStateException: Duplicate key org.jetbrains.jps.model.module.impl.JpsModuleImpl@50eac852

这不是Maven项目，所以我不知道是什么原因造成的

Answer 1

与https://youtrack.jetbrains.com/issue/IDEA-225394相关-内部错误：（java.lang.IllegalStateException）键重复

仅在关闭Intellij并删除目录C:\Users\UserName\AppData\Local\JetBrains\IntelliJIdea2020.1

后，我设法修复了此类问题

选择Run -> Run并运行com.appointment.publishing in spring-boot-app后，项目将首次正常运行。

在项目上修改测试文件并尝试多次运行后，它将引发以下异常。

扔掉它之后，修复它的唯一方法是继续Build -> Rebuild Project。

但是，如果您尝试运行项目多次（在修改测试文件之后），问题就会再次发生。

在调用Build-> Build Project后，我注意到以下错误：

更新：右键单击父pom.xml-> Maven->重新导入后，该异常消失了。

有时仅删除IntelliJIdea2020.1目录是不够的。我还必须删除我的C:\Users\UserName\.m2目录。

@Jet Brains团队：问题是由重复的工件配置文件引起的。为了对其进行修复，您需要从.idea / artifacts目录中删除application_name_war_exploded2.xml和application_name_war2.xml文件。不确定为什么会产生这些重复的工件。您是否在File | File中手动编辑了工件配置？项目结构神器？

Answer 2

我必须右键单击，将鼠标悬停在 Maven 上，然后单击下载源代码和文档

为我解决了

重复键org.jetbrains.jps.model.module.impl.JpsModuleImpl
