# Nexus Analyzer **Requires Nexus Pro** The Nexus Analyzer will check for the Maven GAV (Group/Artifact/Version) information for artifacts in the scanned area. This is done by determining if an artifact exists in a Nexus Pro installation using the SHA-1 hash of the artifact scanned. If the artifact's hash is found in the configured Nexus repository, its GAV is recorded as an Identifier and the Group is collected as Vendor evidence, the Artifact is collected as Product evidence, and the Version is collected as Version evidence. The Nexus Analyzer has been superceded by the Central Analyzer. If both the Central Analyzer and Nexus Analyzer are enabled and the Nexus URL has not been configured to point to an instance of Nexus Pro the Nexus Analyzer will disable itself. ## Logging You may see a log message similar to the following during analysis: ``` WARNING: There was an issue getting Nexus status. Disabling analyzer. ``` At the beginning of analysis, a check is made by the Nexus analyzer to see if it is able to reach the configured Nexus service, and if it cannot be reached, the analyzer will be disabled. If you see this message, you can use the configuration settings described in either the CLI, Ant, Maven, or Jenkins plugins to resolve the issue, or disable the analyzer altogether. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
