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.

user_15545300

if you want to deploy the war. what worked for me is both

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

and

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <inherited>true</inherited>
            <version>3.8.1</version>
            <configuration>
                <source>16</source>
                <target>16</target>
                <compilerArguments>
                    <endorseddirs>${endorsed.dir}</endorseddirs>
                </compilerArguments>
            </configuration>
        </plugin>

Please note the versions.

I experienced the same issue after upgrading from JDK 1.8 to JDK 17 and I solved it by upgrading the plugin version.

Before:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.3</version>
</plugin>

After:

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

I have solved this by simply going in the Jenkins global tool configuration and changing the path of JDK to /usr/local/Cellar/openjdk@11/11.0.10. Previously it was /usr/local/Cellar/openjdk/16.0.1 in my local machine MAC.

Eclipse 2021-06 release by default JDK will be set to 16. So changed to your preferred JDK version. or configure your default JDK to run enter image description here

I had this exact same issue. After updating the POM file, I needed to delete my .m2/repository folder before running mvn install for the project.
