I am learning Selenium and I would like to try add the maven-compiler-plugin to pom.xml and reimport maven settings. So I found this example to do it http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html and tried to add the code to the pom.xml. But the vrsion from the example 3.8.1 is red like on the screenshot. What it means? It is a copy from example.

enter image description here

Here is the whole pom.xml

you can go to Maven Central and look for that dependency, I see it at: mvnrepository.com/artifact/org.apache.maven.plugins/…, so maybe you connected to a VPN ? or there is a repository configuration somewhere in your project ?, also will be more helpful if you post your entire pom.xml in a text snippet – Niela
I am on VPN. How is it related to loading plugins? – Brittan
maybe there is a HOST name resolution error, I've been into problems because of that like not finding some sites, had to change for Google DNS (8.8.8.8) – Niela
Try cleaning/deleting your maven-compiler-plugin folder (and only that folder) in your local .m2 – Niela
Added pom.xml ... – Brittan
I just compiled it with mvn and is just working fine: [INFO] --- maven-compiler-plugin:3.8.1:compile (default-compile) @stackoverflow-maven-compiler-plugin-error – Niela
After target in target folder it is ok. Thanks. – Brittan
Please try to build your project on plain command line and safe the logging output ...that might help more. – Racy
@AlexAndrade That's not official maven Central Repository Database, that's a third party. The official is search.maven.org search.maven.org/artifact/org.apache.maven.plugins/… – Variform

In my case, I have changed the tags from plugin to dependency like it is in the Maven Repository.

<dependency>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
</dependency>

In my case the groupId for the plugin was missing:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.0</version>
...

In my case, Spring Boot code works fine without changing anything, however, it gives the same error when I tried to commit in Git.

To solve this, I add the version info as follows and it worked.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler-plugin.version}</version>
    ...

I've faced this issue with my old project (which was 100% working on my old ItelliJ IDEA) and newly installed ItelliJ IDEA: in the pom.xml I had this:

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.2</version>
            <configuration>
                <source>${java.version}</source>
                <target>${java.version}</target>
            </configuration>
        </plugin>
    </plugins>
</build>

And IDEA throwed an error maven-compiler-plugin not found. I've added

<groupId>org.apache.maven.plugins</groupId>

and IDEA found the plugin, and after that I was free to remove org.apache.maven.plugins without breaking IDEA

I got this error with IntelliJ. tried many ways, the below worked for me:

  1. Close your IDE.
  2. Delete "*.iml" and ".idea" -directories(present in the root folder of project)
  3. Run "mvn clean install" from the command-line
  4. Re-import your project into IDEA

In IntelliJ you can right click on 3.8.1 scroll down to Maven and select "Reimport". This solved the issue for me.

In my case, invalidating cache and restarting solved the issue.

I went to

.m2\repository\org\apache\maven\plugins\maven-compiler-plugin

and removed older version. It worked

Add the Following code in your pom the issue will resolve

 <build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <source>8</source>
                <target>8</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>3.0.0-M1</version>
            <configuration>
                <useSystemClassLoader>false</useSystemClassLoader>
                <forkCount>1</forkCount>
                <useFile>false</useFile>
                <skipTests>false</skipTests>
                <testFailureIgnore>true</testFailureIgnore>
                <forkMode>once</forkMode>
                <suiteXmlFiles>
                    <suiteXmlFile>testing.xml</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>
    </plugins>
</build>
<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

Make sure you are reimporting your dependency after adding plugins

You need to update your project so that the dependencies are updated from Maven side.

To update:

  1. Change the file structure to project view.
  2. Right click on project name -> Maven -> Reload project

And it will download all the necessary dependencies.

One reason could be due to proxy setup on your system in Maven settings.

You can remove/backup the previous maven settings.xml file and this should work.

mv ~/.m2/settings.xml ~/.m2/settings.xml.bak
