Plugin configurations
Plugin configurations are sets of parameters that apply across some or all of the plugin procedures. They reduce repetition of common values, create predefined parameter sets for end users, and securely store credentials where needed. Each configuration is given a unique name that is entered in designated parameters on procedures that use them.

-
Go to to open the Plugin Manager.
-
Find the EC-Nexus-1.2.1.2021081117 row.

Plugin procedures
Retrieve Artifact from Nexus
Retrieves the specified artifact from repository and saves the attributes.
Retrieve Artifact from Nexus parameters
| Parameter | Description |
|---|---|
Configuration | Previously defined plugin configuration. |
Repository | Id of the Nexus repository from which to retrieve artifact. |
Repository Format | Format (for example Maven2, npm, NuGet etc.,) used to store, retrieve and index Components (for example packages, binaries, libraries, containers etc.,) |

Overwrite? | Overwrite if already exists in destination? |
Result Property Sheet | Property under which retrieved-artifact results are saved. By default it would use the namespace which starts with '/myJob/retrievedArtifactVersions/$[resourceName]' |
Get Latest Artifact Version
Procedure will get and save the latest artifact’s version to the specified property
Get Latest Artifact Version parameters
| Parameter | Description |
|---|---|

Known issues
-
Nexus cannot return information about the remote artifact that was not cached yet. If you are retrieving artifact that already exists at the destination, retrieve will fail because the artifact is missing in the Nexus cache, unless you will check the "Overwrite" parameter.
-
Plugin relies on the status endpoints to assume the version of NXRM. Endpoint 'service/rest/v1/status' is used for NXRM 3 and 'service/local/outreach/status' for NXRM 2
