Sonatype Nexus 3 get last updated/uploaded artifact

Question

I have such maven-metadata.xml file content:

<groupId>com.ifact</groupId>
<artifactId>xxxx-exporter</artifactId>
<versioning>
<latest>0.0.21</latest>
<release>0.0.21</release>
<versions>
<version>0.0.1</version>
<version>0.0.2</version>
<version>0.0.3</version>
<version>0.0.4</version>
<version>0.0.5</version>
<version>0.0.6</version>
<version>0.0.7</version>
<version>0.0.8</version>
<version>0.0.9</version>
<version>0.0.10</version>
<version>0.0.11</version>
<version>0.0.12</version>
<version>0.0.13</version>
<version>0.0.14</version>
<version>0.0.15</version>
<version>0.0.16</version>
<version>0.0.17</version>
<version>0.0.18</version>
<version>0.0.19</version>
<version>0.0.20</version>
<version>0.0.20-1</version>
<version>0.0.20-2</version>
<version>0.0.21</version>
</versions>
<lastUpdated>20191206104706</lastUpdated>
</versioning>
</metadata>

And we saw that 0.0.21 is the latest artifact version. (was created Sun Dec 01 2019 13:28:29 GMT+0200)

AND

0.0.20-1 (was created Fri Dec 06 2019 12:47:03 GMT+0200)

0.0.20-2 (was created Fri Dec 06 2019 12:46:21 GMT+0200)

So maven-metadata.xml sort files not by creation date, it sort by version.

But I need to get the last updated/uploaded artifact and I cannot rely on the contents of the maven-metadata.xml file.

I try to use API call: http://127.0.0.1:8081/service/rest/v1/search/assets?sort=&repository=xxxx-exporter-release&maven.extension=jar

And saw a correct out:

}

API sort them by creation time or last uploaded. But if we download an artifact that mark latest 0.0.21 in maven-metadata.xml. And after this make API call again http://127.0.0.1:8081/service/rest/v1/search/assets?sort=&repository=xxxx-exporter-release&maven.extension=jar

At response we saw:

      }
    }

  "continuationToken": null
}

The last downloaded artifact becomes the latest in API response.

How can I get the last updated/uploaded artifact?
