maven-site plugins 3.3 java.lang.ClassNotFoundException: org.apache.maven.doxia.siterenderer.DocumentContent

Question

Since this night, maven site 3.3 plugins stop to work.

Try to delete local repository, but no change. Maven 3.3.9 java 1.8

No config or dependencies defined in pom for site plugins

[WARNING] Error injecting: org.apache.maven.report.projectinfo.CiManagementReport
java.lang.NoClassDefFoundError: org/apache/maven/doxia/siterenderer/DocumentContent

Answer 1

I had just started to get this issue also during builds. What worked for me was to specifically define the maven-site-plugin and the maven-project-info-reports-plugin along with the version numbers in the pom.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-site-plugin</artifactId>
  <version>3.7.1</version>
</plugin>
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-project-info-reports-plugin</artifactId>
  <version>3.0.0</version>
</plugin>
