`mvn site`でMavenレポートを生成しますが、以下のエラーが発生します 

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

Maven 3.6.0__でテスト済み

解決策

デフォルトの `maven-site-plugin:3.3`プラグインを使用せず、最新のバージョン、例えば3.7.1にアップグレードしてください

pom.xml 

    <build>
        <plugins>

            <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>

        </plugins>
    </build>
