将 Mobilefirst CLI 6.3.0 升级到 7.0

Question

将 mobilefirst 6.3 CLI 升级到 mobilefirst 7.0 CLI 是否存在任何已知问题？

在 ubuntu 14.0.x 中自动升级失败并出现以下错误，之前在 6.3.0 中它可以正常工作。

运行 mfp build -dd 时出错

虽然正在根据 APAR PI37526 调查使用 CLI 的升级问题，但您可以打开 PMR 进行跟踪。

如果 android\native 文件夹缺少 project.properties 文件，也可能会发生该错误。验证此文件是否存在于您的 MFP 项目的 android\native 文件夹中。

您可以使用instructions here 或通过 Google ADT 的命令行工具重新生成此文件。

作为一种解决方法，您可以将 6.3 项目导入 MobileFirst Studio v7.0；我至少可以确认，在使用 Studio 时，问题中提到的升级错误不会发生，并且 ProGuard 文件正在添加到升级后的项目中。
