java - 将主项目jar添加到项目根文件夹中

Question

Apache Maven 3.3.3
OS name: "windows 7"

我的 mvn 项目中有主类:

src/main/java/rev/App.java

App.java是默认的maven main “Hello World!”

然后，我将依赖项放入根目录的 lib 文件夹中(下面的 assembly.xml ):

......

但是，执行此操作后，项目的主 jar 不会出现在文件夹中的任何位置。如何让主 jar 与 lib 文件夹一起出现在根文件夹中？

pom.xml:

Answer 1

您需要在程序集配置中显式添加构建的项目 jar。

<files>
    <file>
       <source>${project.basedir}/target/${project.build.finalName}.jar</source>
       <outputDirectory>/</outputDirectory>
    </file>
</files>
