我正在尝试从Jenkins v2.134发布Android Singed apk，成功生成了已签名的apk（（可以手动上传-已测试）。但是当涉及到发布时，它将失败并出现以下异常。
我正在使用JSON密钥访问Google API和服务。并且创建的用户还具有所需的必需权限。首先是默认版本showing some problem and I downgrade some version of plugins as they suggested。
Googleplayandroidpublisher v1.5 ，
令牌宏v1.10 ，
Google OAuth v0.3 。
但是将签名上传到Android Playstore时会出现此异常
