Maven - Error when trying to build project

Question

I looked at the answer to someone who had a similar issue but I couldn't find it a solution to my problem. I'm unable to build my project:

[INFO] --- maven-site-plugin:3.3:site (default-site) @ myproject---
[INFO] configuring report plugin org.apache.maven.plugins:maven-project-info-reports-plugin:3.0.0
[WARNING] Error injecting: org.apache.maven.report.projectinfo.CiManagementReport
 java.lang.NoClassDefFoundError: org/apache/maven/doxia/siterenderer/DocumentContent
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.3:site (default-site) on project myproject: 
        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:3.3:site: org/apache/maven/doxia/siterenderer/DocumentContent

I've added two plugins and a dependency which are the following, two plugins:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-site-plugin</artifactId>
            <version>3.3</version>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-project-info-reports-plugin</artifactId>
            <version>3.0.0</version>
        </plugin>
        <plugin>

The dependency:

    <dependency>
        <groupId>org.apache.maven.doxia</groupId>
        <artifactId>doxia-site-renderer</artifactId>
        <version>1.8</version>
    </dependency>

Any help would be appreciated it, I generally don't understand what is left.

Answer 1

maven-site-plugin in version 3.3 requires doxia-site-renderer 1.4, according to pom . Is there a reason you included doxia-site-renderer dependency explicitly?

To solve the issue you can downgrade doxia-site-renderer to 1.4 or upgrade maven-site-plugin to 3.7 which requires doxia-site-renderer 1.8

Answer 2

I got this error with no plugins configured. It seems that maven falls back to 3.3 of the site plugin when it is not there. I configured it for 3.7 and then the error disappeared. (Only getting css's and images at this point though.... :-() ) The site plugin gets the doxia thing implicitly so it should not be needed in the config.
