原生混合Flutter Module,打release包报错

错误信息如下

Execution failed for task ':app:lintVitalRelease'.
> Could not resolve all artifacts for configuration ':app:debugRuntimeClasspath'.
   > Failed to transform libs.jar to match attributes {artifactType=processed-jar, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime}.
      > Execution failed for JetifyTransform: /Users/lhz/Documents/AndroidProject/hb_unicom_flutter/.android/Flutter/build/intermediates/flutter/debug/libs.jar.
         > Transform's input file does not exist: /Users/lhz/Documents/AndroidProject/hb_unicom_flutter/.android/Flutter/build/intermediates/flutter/debug/libs.jar. (See https://issuetracker.google.com/issues/158753935)

这个问题的解决方法就在链接https://issuetracker.google.com/issues/158753935 中，需要翻墙访问。

结论就是这是构建时的一个BUG,Google应该会在新版本gradle中修复，现在的解决方法就是:

• 如果错误信息中是提示缺少 debug/libs.jar, 先执行flutter run --debug 成功后，再执行打包操作即可。
• 如果错误信息中是提示缺少 profile/libs.jar, 先执行flutter run --profile 成功后，再执行打包操作即可。

其实就是通过执行相应命令，生产缺少的jar文件。
