所以这是一个spring MVC应用程序。 我需要编制,建造和包装的目标(一场爆炸性的生产战争)。
我从哪里开始?
我希望能够通过命令行完成所有这些操作,因此它可以独立于IDE。
更新的 所以运行mvn clean install工作了!
为什么我的课程会重复?
1) in the /classes folder
2) /myapp-1.0/web-inf/classes folder.

尝试
mvn clean install
答案 1 :(得分:3)
刚运行mvn无济于事。您需要运行mvn clean install
或mvn clean test
。
答案 2 :(得分:3)
也许你可以用mvn包
我会再给你一些关于同一个
的指示Maven使用本地存储库来下载和保存您的jar文件 - 通常位于“C:\ Docs n Settings \ user.m2”文件夹中
mvn install将打包你的war并将其安装到项目的组ID,工件ID和版本指定的包结构下的.m2文件夹中。
mvn package会将您的项目打包成战争并将其与爆炸战争一起放入目标文件夹中。您可以使用maven-war-plugin指定输出目录。
maven clean将清理目标文件夹(删除它)。因此,您可以使用maven clean package清理目标并重新创建它。
如果您的罐子已经下载,离线模式将有助于加快速度。使用可以使用-o。
您的编译类位于pom中build标记指定的文件夹下。
请根据需要使用mvn -o clean package / mvn clean package或mvn package。如果您需要本地仓库中的战争,请使用mvn install
阅读this链接了解详情。它说Jar在链接中,但它取决于你提到的包装。
答案 3 :(得分:3)
mvn clean install
右键单击maven项目 1.运行As-&gt; Maven Clean 2.运行As-&gt; Maven Install
就我而言,没有生成类文件。它们将在Maven安装步骤中生成。
