Maven plugins can not be found in IntelliJ

Question

After updating IntelliJ from version 12 to 13, the following Maven-related plugins cannot be resolved:

org.apache.maven.plugins:maven-clean-plugin:2.4.1
org.a         


        

Answer 1

Enabling "use plugin registry" and Restart project after invalidate cash solved my problem

to Enabling "use plugin registry" >>> (intelij) File > Setting > Maven > enable the option from the option list of maven

To invalidate cash >>> file > invalidate cash

That's it...

Answer 2

In my case, there were two slightly different dependences (version 2.1 vs 2.0) in two maven sub-modules. After I switched to a single version the error has gone in IDEA 14. (Refresh and .m2 swipe didn't help.)

Answer 3

I had the same issue. I added the plugins into my pom.xml dependencies and it works for me.

    <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>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-deploy-plugin</artifactId>
        <version>2.7</version>
        <type>maven-plugin</type>
    </dependency>

Answer 4

For me which worked is putting the repository which contained the plugin under pluginRepository tags. Example,

<pluginRepositories>
    <pluginRepository>
        <id>pcentral</id>
        <name>pcentral</name>
        <url>https://repo1.maven.org/maven2</url>
    </pluginRepository>
</pluginRepositories>

Answer 5

If you have red squiggles underneath the project in the Maven plugin, try clicking the "Reimport All Maven Projects" button (looks like a refresh symbol).

Answer 6

My case:

• 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.
