IntelliJ从12版本升级到13版本后，以下maven相关插件无法解决:
org.apache.maven.plugins:maven-clean-plugin:2.4.1
org.apache.maven.plugins:maven-deploy-plugin
org.apache.maven.plugins:maven-install-plugin
org.apache.maven.plugins:maven-site-plugin
在使用IntelliJ 12时，这些不在插件列表中。不知何故，它们在更新后被添加，现在IntelliJ抱怨无法找到它们。我可以在哪里从列表中删除这些插件或通过安装它们来解决问题?
我可以运行maven目标干净和编译没有问题，但配置文件/插件在IDE中显示红色警告。

删除本地Maven未知插件并重新导入所有Maven项目。这将解决这个问题。
你可以在View > Tool Windows > Maven下找到它:

如果你在Maven插件的项目下面有红色的涂鸦，试着点击“重新导入所有Maven项目”按钮(看起来像一个刷新符号)。
解决了! !
这就是我解决问题的方法……
Tried one of the answers which include 'could solve it by enabling "use plugin registry" '. Did enable that but no luck. Tried again one of the answers in the thread which says 'If that does not work, Invalidate your caches (File > Invalidate caches) and restart.' Did that but again no luck. Tried These options .. Go to Settings --> Maven --> Importing and made sure the following was selected Import Maven projects automatically Create IDEA modules for aggregator projects Keep source... Exclude build dir... Use Maven output... Generated souces folders: "detect automatically" Phase to be...: "process-resources" Automatically download: "sources" & "documentation" Use Maven3 to import project VM options for importer: -Xmx512m But again no success. Now lets say I had 10 such plugins which didn't get resolve and among them the first was 'org.apache.maven.plugins:maven-site-plugin' I went to '.m2/repository/org/apache/maven/plugins/' and deleted the directory 'maven-site-plugin' and did a maven reimport again. Guess what, particular missing plugin got dowloaded. And I just followed similar steps for other missing plugins and all got resolved.
在我的例子中，在两个maven子模块中有两个略有不同的依赖项(版本2.1 vs 2.0)。在我切换到单一版本后，错误已经在IDEA 14中消失了。(刷新和。m2滑动没有帮助。)
IntelliJ IDEA和Maven -“未解决的插件”解决方案”-特别是删除插件文件夹-然后在ide重启后重新导入所有Maven插件-对我有用。
这对我很有效
进入设置—> Maven—>导入—>导入器的JDK—> 使用“使用项目JDK”选项，而不是之前的自定义JDK集。 重新构建/重新导入所有依赖项。
