Github Action

密钥导出

gpg --export-secret-keys 7BDDF87A > /tmp/secring.gpg

将密钥进行base64编码

base64 /tmp/secring.gpg > /tmp/secring.gpg.b64

name	value
MAVEN_PASSWORD	sonatype仓库密码
MAVEN_USERNAME	sonatype仓库用户名
SIGNING_KEY_ID	GPG证书ID
SIGNING_PASSWORD	GPG密码
SIGNING_SECRET_KEY_RING_KEY	GPG文件密钥base64编码

将SIGNING_SECRET_KEY_RING_KEY值设置为上面的secring.gpg.b64文件内容

在github右边创建Release版本即可自动打包上传

查看action的打包运行情况

最后登录 sonatype 把上传的项目进行close > release 即可发布
