gradle - 错误信息是什么意思：“密钥环不以密钥标签开头：标签 0xffffffff”？
问题描述
这是我在尝试使用 gradle 签名插件签名并发布到本地 maven .m2 目录时遇到的错误：

最后一条错误消息揭示了几个问题：
我只需要使用 1 个密钥（及其密码）对工件进行签名，为什么此操作依赖于包含多个几乎无用的密钥的密钥环？
什么是密钥标签？是密钥 ID、密钥名称还是密钥校验和？
为什么密钥环必须以 0xffffffff 开头？这个十六进制数字有什么特别之处？
非常感谢您的意见
解决方案
如果没有更多关于您如何准确配置 Gradle 插件的详细信息，很难确切地说出哪里出了问题。我相信这个问题很可能是一个错误的密钥环文件或一个错误的内存密钥。构造PGPSecretKeyRing函数没有找到预期的密钥标签，而是在您的情况下找到0xffffffff了。
考虑到这一点，让我试着回答你的三个问题：
- 我看到了两种可能的可能性：
PGPSecretKeyRing无论您使用密钥环文件还是仅使用单个密钥，该插件都只是在后台使用，或者- 您错误地配置了插件。
- “密钥标签”是属于 OpenPGP 格式一部分的数据包标签之一。在您的情况下找不到该标签，这就是为什么我认为某些内容配置错误（例如，通过以错误的格式传递密钥）。
- 同样，
0xffffffff不是预期的标签，而是在您的案例中实际找到的标签。预期的标签是“秘密密钥包”，即0x5.
还有一些可能实际上可以帮助您解决问题的指针：
- 我的另一个 SO 回答帮助同样面临“无法读取 PGP 密钥”错误的人。
- 一个 Gradle 问题，人们面临同样的
PGPSecretKeyRing错误，并且至少有人找到了解决方案。
