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。

其他的答案都对我没用。对我来说有效的解决方案是通过cmd手动下载丢失的工件:
mvn dependency:get -DrepoUrl=http://repo.maven.apache.org/maven2/ -Dartifact=ro.isdc.wro4j:wro4j-maven-plugin:1.8.0
在此更改之后，需要让Idea了解新的可用工件。这可以在“设置> Maven >存储库”中完成，选择那里的“本地”，然后简单地单击“更新”。
编辑:-DrepoUrl似乎已弃用。- dremoterepository应该用。来源:Apache Maven依赖插件-依赖:获得。

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.
尝试了无效缓存，重新导入项目，部分和整体删除.m2文件夹，并切换到Idea捆绑的Maven。 没有任何工作，我最终完全破坏了Maven:当它在控制台中构建项目时，现在它停止了。 不得不重新安装Maven，它帮了大忙!
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.
这对我来说很管用……删除“C:\Users[Windows用户帐户].m2\repository”下的所有文件夹和文件。
最后在IntelliJ的Maven项目选项卡中运行“重新导入所有Maven项目”。
