Error:Execution failed for task

Error:Execution failed for task ':app:validateSigningRelease'.

打包无意中出现了这个问题

Error:Execution failed for task ':app:validateSigningRelease'.
> Keystore file C:\hello\project\SadjAppClient\files\sadjapp.jks not found for signing config 'externalOverride'.

原因：签名文件的路径被修改了，或者此路径不存在签名文件了

解决：修改一下.jks签名文件的签名路径即可
