Plugin 'org.apache.maven.plugins:maven-compiler-plugin:' not found

As an AI language model, I cannot access your system to diagnose your issue. However, the error message suggests that the Maven compiler plugin is either missing or not installed correctly. You can try the following solutions:

1. Check if the plugin is declared correctly in the project's pom.xml file. The declaration should look like this:

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

2. Try updating the Maven compiler plugin to the latest version.

3. Check if your Maven installation is up-to-date and functioning correctly.

4. If none of the above solutions work, try deleting the local repository cache and re-downloading the dependencies.

If the issue persists, you can seek help from the Maven community or your development team.
