任务“：app：packageDebug”的执行失败。无法生成v1签名

Question

我正在使用命令为Android平台构建离子应用程序

ionic cordova build android

我总是会收到此错误。

BUILD FAILED in 11s
/home/ashleypow/Documents/InfoSecDevelopers/Projects/To-Do-App/To-Do-App/platforms/android/gradlew: Command failed with exit code 1 Error output:
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:packageDebug'.
> Failed to generate v1 signature

我尝试了stackoverflow和ionicforum的所有解决方案，但似乎没有任何效果。 有人可以帮忙。在过去的三天里，我一直坚持下去。 预先感谢！
