准备1

创建上传空间并验证，用自己的github验证
https://central.sonatype.com/publishing/namespaces

准备2

生成 GPG 密钥(ai就行)

查看私钥

gpg --list-secret-keys --keyid-format LONG

输出结果

sec   rsa4096/ABCDEF1234567890 2024-01-01 [SC]

      1234567890ABCDEF1234567890ABCDEF1234

uid   [ultimate] Your Name <[you@email.com](mailto:you@email.com)>

生成签名key

gpg --export-secret-keys -a ABCDEF1234567890 > signing.key

查看短key id

gpg --list-secret-keys --keyid-format SHORT
输出结果

sec   rsa4096/F15BDBF5 2026-02-06 [SC]

      2439E7FADB65F3B96D997E9637D204E3F15BDBF5

uid           [ 绝对 ] xxxx <[xxxx@qq.com](mailto:xxxx@qq.com)>

ssb   rsa4096/F64AB908 2026-02-06 [E]

gradle.properties GPG配置

signing.keyId=短key id
signing.password=密码
signing.gnupg.useLegacyGpg=true
signing.keyFile=生成签名key地址
