Fix ClassNotFoundException
in Nexus Repository
✅ Solution
ClassNotFoundException in Nexus Repository usually means a required JAR file or a dependency is missing from the classpath or not loaded correctly. To fix it, ensure the relevant plugin JAR files are placed in the correct Nexus plugins directory (e.g., sonatype-work/nexus3/plugins) and that the plugin is compatible with your Nexus Repository version. Restart Nexus after adding the JARs for the changes to take effect.
