如何在Eclipse中创建Maven项目

Question

我是eclipse的新手。从今天开始，我开始工作eclipse。 我的要求是在eclipse.net中生成一个简单的maven项目，因此我将我的maven放在我的C驱动器中并运行mvn -version.it显示版本，并且我假设已安装maven。

现在我试图在我的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

尝试执行此步骤。

1）在Eclipse IDE中，导航到“文件”>“新建”>“其他...”，以调出项目创建向导。

2）滚动到Maven文件夹，打开它，然后选择Maven Project。 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。 就本教程而言，我们将选择简单的项目。 这将创建一个基本的，启用Maven的Java项目。 如果需要更高级的设置，请取消选中此设置，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，您将需要输入有关正在创建的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 ）。 通常，组ID应与您的组织名称相对应，工件ID应与项目名称相对应。 版本以及包装和其他字段均由您决定。 如果这是一个没有父项依赖项的独立项目，则可以保留“父项”部分。 填写适当的信息，然后单击完成。

5）您现在将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，并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文件以查看Maven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，以查看其中的pom文件的依赖关系，依赖关系层次结构，有效POM和原始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。
