如何在Eclipse中創建Maven項目

Question

我是eclipse的新手。從今天開始，我開始工作eclipse。 我的要求是在eclipse.net中生成一個簡單的maven項目，因此我將我的maven放在我的C驅動器中並運行mvn -version.it顯示版本，並且我假設已安裝maven。

現在我試圖在我的cmd中執行以下命令，但它總是顯示錯誤。

mvn archetype:generate -DgroupId=com.selva -DartifactId=SampleApplication -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

錯誤是

C:\Users\selva>mvn archetype:generate -DgroupId=com.selva
rtifactId=SampleApplication -DarchetypeArtifactId=maven-archetype-qui
tart -DinteractiveMode=false

我想在Eclipse中創建一個簡單的Maven項目。 任何幫助將不勝感激！

Answer 1

嘗試執行此步驟。

1）在Eclipse IDE中，導航到“文件”>“新建”>“其他...”，以調出項目創建向導。

2）滾動到Maven文件夾，打開它，然后選擇Maven Project。 然后選擇下一步。

3）您可以選擇創建一個簡單的項目或放棄此選項。 就本教程而言，我們將選擇簡單的項目。 這將創建一個基本的，啟用Maven的Java項目。 如果需要更高級的設置，請取消選中此設置，您將能夠使用更高級的Maven項目設置功能。 保留其他選項不變，然后單擊“下一步”。

4）現在，您將需要輸入有關正在創建的Maven項目的信息。 您可以訪問Maven文檔以更深入地了解Maven坐標（ http://maven.apache.org/pom.html#Maven_Coordinates ）。 通常，組ID應與您的組織名稱相對應，工件ID應與項目名稱相對應。 版本以及包裝和其他字段均由您決定。 如果這是一個沒有父項依賴項的獨立項目，則可以保留“父項”部分。 填寫適當的信息，然后單擊完成。

5）您現在將注意到您的項目已創建。 您將把Java代碼放在/ src / main / java中，將資源放在/ src / main / resources中，並將測試代碼和資源分別放在/ src / test / java和/ src / test / resources中。

6）打開pom.xml文件以查看Maven設置的結構。 在此文件中，您可以看到在步驟4中輸入的信息。您還可以使用窗口底部的選項卡進行更改，以查看其中的pom文件的依賴關系，依賴關系層次結構，有效POM和原始xml代碼。 pom.xml選項卡。

現在將使用Eclipse創建帶有Maven的Java項目。

如果您在Eclipse中沒有Maven，請安裝m2e。
