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。

我的情况:
maven-javadoc-plugin with version 3.2.0 is displayed red in IntelliJ. Plugin is present in my local maven repo. Re-imported maven million times. Ran mvn clean install from the command line N times. All my maven settings in IntelliJ are correct. Tried to switch between Bundled and non-bundled Maven. Tried do delete the whole maven repo and to delete only the plugin from it. Nothing of the above worked. The only thing that almost always helps with modern IntelliJ IDEA versions is "Invalidate caches / Restart". It helped this time as well. maven-javadoc-plugin is not red anymore, and I can click on it and to to the source pom file of the plugin.

这些方法对我来说都没用。在经历了痛苦的几个小时后，我发现这个问题是由我导入项目的方式引起的。
上下文:导入带有Web和Kafka依赖项的新生成的Spring Initializr项目。
问题:插件依赖“未找到”，IntelliJ无法编译应用程序，即使mvn清洁编译在控制台上运行良好。
坏的方法:使用“New > Project from Existing Sources…”选项导入它。
好的方法是:使用“Open…”选项导入它。
从坏到好的解决方案:删除项目，从版本控制中删除并重新克隆repo，以确保所有gitignored IntelliJ文件都被删除，并使用“Open…”选项将其导入IntelliJ。
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。)
红色警告maven-site-plugin在构建站点生命周期后解决:
我的IntelliJ版本是Community 2017.2.4

取消选中Maven设置中的“脱机工作”复选框。
