java复制密钥组织。喷气式飞机。jps。模型单元impl。JpsModuleImpl

Question

我的项目一直运行良好，直到今天我在intelIj中打开它并尝试运行它，我发现这个错误

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

这不是一个maven项目，所以我不明白是什么原因造成的

Answer 1

单击重新导入所有Maven项目——上图左侧的第一个图标

为我工作

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

帮我解决了

Answer 3

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

I managed to fix something like this only after closing Intellij and deleting the directory C:\Users\UserName\AppData\Local\JetBrains\IntelliJIdea2020.1

After selecting Run -> Run and running com.appointment.publishing in spring-boot-app the project works fine for the first time.

After modifying the test file on the project and trying to run it more times, it throws the following exception.

After throwing it, the only way to fix it, is going on Build -> Rebuild Project.

However, the problems start happening again if you try to run the project more than one time (after modifying the test file).

I noticed following error after invoking Build -> Build Project:

Update: The exception has disappeared after right click on parent pom.xml -> Maven -> Reimport.

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

@Jet Brains Team: The problem is caused by duplicated artifact configuration files. In order to fix it, you need to delete application_name_war_exploded2.xml and application_name_war2.xml files from .idea/artifacts directory. Not sure why these duplicating artifacts were produced though. Did you edit artifact configurations manually in File | Project Structure | Artifacts?
