mvn安裝不在eclipse中工作，但從命令行工作正常

Question

我無法通過eclipse建立一個項目，但它運行良好，當我運行mvn乾淨安裝。我收到以下問題。

確保JDK您使用的命令行是一樣的，你正在使用你的IDE。

在命令行鍵入：

java -version 

然後在蝕：

windows -> preferences -> Installed JREs 

---

這同樣適用於行家：

在命令行鍵入：

mvn -version 

在Eclipse：

windows -> preferences -> Maven -> User settings 
windows -> preferences -> Maven -> Installations
