java - 如何在eclipse中创建Maven项目

Question

我是 eclipse 的新手。我从今天开始使用 eclipse 。 我的要求是在 eclipse 中生成一个简单的 maven 项目。所以我将 maven 放在我的 c 驱动器中并运行 mvn -version。它显示版本，我假设 maven 已安装。

现在我尝试在 cmd 中执行以下命令。但它总是显示错误。

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

错误是

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

我想在eclipse中创建一个简单的maven项目。 任何帮助将不胜感激!

Answer 1

尝试执行以下步骤。

1) 在 Eclipse IDE 中，导航至"file">“新建”>“其他...”以打开项目创建向导。

2) 滚动到 Maven 文件夹，将其打开，然后选择 Maven 项目。然后选择“下一步”。

3) 您可以选择创建一个简单的项目或放弃此选项。出于本教程的目的，我们将选择简单项目。这将创建一个基本的、启用 Maven 的 Java 项目。如果您需要更高级的设置，请不要选中此设置，您将能够使用更高级的 Maven 项目设置功能。保留其他选项不变，然后单击“下一步”。

4) 现在，您需要输入有关您正在创建的 Maven 项目的信息。您可以访问 Maven 文档以更深入地了解 Maven 坐标 ( http://maven.apache.org/pom.html#Maven_Coordinates )。一般来说，Group Id 应与您的组织名称相对应，Artifact Id 应与项目名称相对应。版本以及包装和其他字段均由您自行决定。如果这是一个没有父依赖项的独立项目，您可以按原样保留“父项目”部分。填写适当的信息，然后单击“完成”。

5)您现在会注意到您的项目已创建。您将把 Java 代码放在/src/main/java 中，将资源放在/src/main/resources 中，将测试代码和资源分别放在/src/test/java 和/src/test/resources 中。

6) 打开pom.xml文件，查看Maven已经设置的结构。在此文件中，您可以看到在步骤 4 中输入的信息。您还可以使用窗口底部的选项卡进行更改以查看依赖关系、依赖关系层次结构、有效 POM 以及 pom 文件的原始 xml 代码pom.xml 选项卡。

现在将使用 Eclipse 创建带有 Maven 的 java 项目。

如果您在 Eclipse 中没有 Maven，请安装 m2e 。
