BUILD FAILED in 37s
解決辦法:
1.1 檢查項目中的版本當前是27，改成28（注意如果有多個component是27的，建議一個一個的改，然後build,如果全部一塊改了，然後build,很可能不成功，實測驗證）
1.2 安裝對應的證書，找到安裝SDK的路徑如:\AppData\Local\Android\Sdk\tools\bin>，cmd後執行:
sdkmanager --licenses
一路點擊 yes
你可能遇到:
.android\repositories.cfg could not be loaded
解決辦法:在.android目錄下新建一個repositories.cfg 文件
1.3 檢查.yml文件中對應發佈的階段版本，是不是你最新的版本，無誤後，然後重新上傳代碼。
