1. 異常現象

從 Intellij IDEA 2017.1 版本升級到當前最新版本 Intellij IDEA 2019.2.2 之后，打開原有的項目時出現異常：

14:42 Unable to import Maven project See logs for details Show Log in Explorer

Intellij IDEA 異常日志：

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 confsettings.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。重新打開原有項目，問題解決。

Maven 庫地址：https://archive.apache.org/dist/maven/maven-3/
