Maven site plugin fails when running on jenkins

Question

I am running maven application "DemoApp" that generates checkstyle static code analysis reports. It works correctly when I run it on eclipse, but when I build it on jenkins it gives the below error

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site plugin:3.3:site (default-site) on project DemoApp: Execution default-site of goal org.apache.maven.plugins:maven-site-plugin:3.3:site failed: A required class was missing while executing org.apache.maven.plugins:maven-site-plugin:3

and The following exception :

java.lang.NoClassDefFoundError: org/apache/maven/doxia/siterenderer/DocumentContent 
Caused by: java.lang.ClassNotFoundException: org.apache.maven.doxia.siterenderer.DocumentContent

I added the following plugins in pom.xml

    <build>
    <pluginManagement>
        <plugins>
            <plugin>

Answer 1

I can't tell whether this solves your current issue but generally: Declarations within <pluginManagement> do not actually set anything in the build process but are intended as a centralized place for declarations common to (sub-)projects:

[...] this only configures plugins that are actually referenced within the plugins element in the children or in the current POM.

See the different versions in the error message: maven-site-plugin:3.3 and in the declaration: <version>3.7.1.

To add such a plugin declaration to the build process you have to declare/reference it additionaly in:

  <build>
    ...
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-site-plugin</artifactId>
      </plugin>
    </plugins>
    ...
  </build>

The same applies to the maven-checkstyle-plugin:

If you want to report to the console or fail the build, you must add an execution of checkstyle::check to the <build> element and configure any options that you need.
