我有一个.jar文件，我想使用Travis上传到Maven Central。我的公司已将创建帐户的Jira票发送给Sonatype，并且该帐户已创建。
我在Travis脚本中输入的用于上传工件的命令如下：
mvn gpg:sign-and-deploy-file \
-DpomFile=stuff/pom.xml \
-Dfile=_build/java/Packager.jar \
-Durl=https://oss.sonatype.org/service/local/staging/deploy/maven2/ \
-DrepositoryId=maven-central \
-Dgpg.passphrase=${mvn_passphrase}
命令的输出以以下错误结尾：
Uploading to maven-central: https://oss.sonatype.org/service/local/staging/deploy/maven2/com/cloudblue/connect-sdk/18.0/connect-sdk-18.0.jar
Uploading to maven-central: https://oss.sonatype.org/service/local/staging/deploy/maven2/com/cloudblue/connect-sdk/18.0/connect-sdk-18.0.pom

有人可以提供有关400错误原因的指导吗？
编辑：我找出了其中一个问题的原因。创建Sonatype帐户时，groupId未设置为正确的值。已修复。现在，使用deploy:deploy-file目标可以正确上传软件包，但是使用gpg:sign-and-deploy-file进行签名并上传文件会引发以下错误：
