Nexus Repository 3（NXRM3）：删除快照任务，不删除带时间戳的工件

Question

我最近设置了NXRM3.13.0-01，并且一直在为maven-snapshots存储库构建工件快照。与我的本地maven构建集成似乎没问题。它从Nexus读取，在构建时部署最新的带时间戳的工件，并在被告知时获取最新的带时间戳的快照。我有一个Maven - 删除快照任务，配置为使用以下配置删除快照：

存储库：所有存储库 快照保留（天）：30 最小快照数：3 如果被释放则删除：是的 释放后的宽限期（天）：7

当此任务运行时，它不会从快照存储库中删除任何内容。我还根据文档运行了Compact Blob Store任务，以防需要回收磁盘空间但无济于事。从日志中，我可以看到两个版本1.0和5.8.01被识别为候选。但是，不会清除任何工件。在日志中，我可以看到以下内容。它找不到要删除的合格工件：

快照存储库如下。我的假设是将删除v5.8.01-SNAPSHOT的前两个，并且将根据任务配置保留较低的两个：

我的问题是：

1. 我错过了什么吗？
2. 我该怎么做才能获得理想的行为？

Answer 1

工件在保留阈值内。将保留设置为零允许按预期删除它们。谢谢@khmarbaise

Answer 2

谢谢@khmarbaise，您的建议也适用于Nexus2.x，但有些人应该关心：

• 设置Minimum snapshot count: 0和Snapshot retention (days): 7意味着如果最近7天没有推送快照，则该工件文件夹中将没有快照。
• 如果选中Remove if released，则在发布版本发布时，将从快照存储库中删除工件文件夹
• 我的Nexus2.x示例
