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。

我也有同样的问题。我将插件添加到pom.xml依赖项中，它为我工作。
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-site-plugin</artifactId>
<version>3.3</version>
<type>maven-plugin</type>
</dependency>
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.4</version>
<type>maven-plugin</type>
</dependency>
<dependency>

<artifactId>maven-deploy-plugin</artifactId>
<version>2.7</version>
<type>maven-plugin</type>
</dependency>

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)。
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。
6月/ 2021:
不删除，不重新导入。
我所做的就是:
C:\Users\dell\.m2\repository\org\apache\maven\plugins
然后双击每个插件文件夹，并查看下载的版本。
然后我回到pom文件，根据下载的版本，我在<version>....中仔细修改了那些版本> < /版本标签。然后刷新。
这样，所有的红色标记都消失了，甚至那些黄色标记也消失了。
所有的清洁。
这是我完整的pom文件，以备进一步通知。该项目是JavaFx+Maven与阴影:

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”。
