Error injecting: org.apache.maven.plugin.war.WarMojo

I had the same problem. I am using Eclipse Jun 2021 release. The problem got resolved after manually configuring one of the recent war plug-ins in POM.xml.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.3.1</version>
</plugin>

You can fix it by changing the JDK in your projects to JDK 14. Left-click on your project and go to properties -> build -> compile . Change the JDK to version 14. If you don’t have JDK 14, you can manage it there by clicking Manage Java Platforms. The download of the JDK is here.

I have solved this by simply going in the Jenkins global tool configuration and changing the path of JDK to /usr/local/Cellar/[email protected]/11.0.10.
Previously it was /usr/local/Cellar/openjdk/16.0.1 in my local machine MAC.
