Could not initialize class org.apache.maven.plugin.war.util.WebappStructureSerializer -Maven Configuration Problem Any solution?

Question

When I am creating a Maven project I am getting this error in pom.xml

Could not initialize class org.apache.maven.plugin.war.util.WebappStructureSerializer
-Maven Configuration Problem

Answer 1

It might because the version of maven-war-plugin is too old in your project.

Try to add below code in your pom.xml

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

Answer 2

<build>
      <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>3.3.1</version>
        </plugin>
    </plugins>
    <finalName>check</finalName>
  </build>
</project>

Note: you should have the build tag place everything inside build tag then, it will not throw error

Answer 3

If you are getting this error within Eclipse (my Eclipse version was Version: 2021-09 (4.21.0), Build id: 20210910-1417 at the time of writing) and you recently tried to move to JDK 17, it appears Eclipse is not compatible with JDK 17. It requires at least JDK 11. I reverted back to Java 11.0.12 and the error has gone away.
