無法在Eclipse Neo中創建Maven項目

Question

嗨，我的系統中有eclipse neo和java1.8。 我已經在Eclipse中添加了drools 6.5 jar，但無法創建Maven項目。

有人可以讓我知道創建Maven項目的完整過程嗎，還是忘了一些事情？

Answer 1

確保在您的IDE中安裝了Maven Integration for Eclipse插件（默認情況下應在Eclipse Neon安裝它）。 為了驗證這一點，請導航至“窗口”->“首選項”，並確保在左首選項列表中列出了Maven 。 如果未安裝maven，請使用Eclipse Marketplace安裝。 如果是這樣，只需通過導航到File-> New-> Other-> Maven-> Maven Project來創建一個新的Maven項目。

Answer 2

您也可以從命令行創建項目

mvn archetype:generate

然后將其作為Maven項目導入eclipse中

下面的示例命令輸出
