1. 例外現象
從 Intellij IDEA 2017.1 版本升級到當前最新版本 Intellij IDEA 2019.2.2 之后，打開原有的專案時出現例外：
14:42 Unable to import Maven project

2. 排查分析
升級前的 Maven 版本是 Apache Maven 3.5.0，升級后版本是 Apache Maven 3.6.2：
1）確認 conf\settings.xml 有無問題，
2）Maven 新老版本兼容有問題：
- 當前 Maven 最新版本 Maven 3.6.2 有可能與最新版的 IDEA 有沖突或兼容問題
- 當前 Maven 最新版本 Maven 3.6.2 本身存在兼容問題
3. 解決方案
下載并使用 Maven 3.6.1 與 Intellij IDEA 2019.2.2 搭配，重新打開原有專案，問題解決，
