我有这样的 maven-metadata.xml 文件内容：

<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>

我们看到0.0.21是最新的神器版本。（创建于2019 年 12 月 1 日星期日 13:28:29 GMT+0200）

和

0.0.20-1（创建于2019 年 12 月 6 日星期五 12:47:03 GMT+0200）

0.0.20-2（创建于2019 年 12 月 6 日星期五 12:46:21 GMT+0200）

所以 maven-metadata.xml 不是按创建日期排序文件，而是按版本排序。

但是我需要获取最后更新/上传的工件，我不能依赖 maven-metadata.xml 文件的内容。

我尝试使用 API 调用： http://127.0.0.1:8081/service/rest/v1/search/assets?sort=&repository=xxxx-exporter-release&maven.extension=jar

并看到了一个正确的结果：

    }

}

API 按创建时间或上次上传对它们进行排序。但是，如果我们在 maven-metadata.xml 中下载一个标记为最新 0.0.21的工件。在此之后再次调用 API http://127.0.0.1:8081/service/rest/v1/search/assets?sort=&repository=xxxx-exporter-release&maven.extension=jar

最后下载的工件在 API 响应中成为最新的。

如何获取最后更新/上传的工件？

Nexus 版本为 Sonatype Nexus Repository ManagerOSS 3.19.1-01
