Question

当我想在我的项目中运行“mvn deploy”时，我收到以下错误：

[INFO] --- maven-deploy-plugin:2.7:deploy (default-deploy) @ JImp ---

我的POM-File看起来像这样：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </dependency>
        <dependency>
            ....
        </dependency>
    </dependencies>
</project>

在我的项目中，我使用了一堆jar文件（如SWT，Log4j等，但也有自己的库）。但所有这些都被添加到我的本地存储库（我自己的库，我通过mvn install：install-file ..添加）和我的POM的依赖项。在Eclipse中我的项目“知道”所有导入，代码看起来很好，没有错误或类似的东西..

如果我只运行

mvn package

然后执行我的jar

java -cp target\JImp-0.0.1-SNAPSHOT.jar de.my.path.JImp

他抛出一个ClassNotFoundException，因为他找不到我自己的lib类。但是这个lib被添加到本地存储库和我的POM-File中的依赖..：/

也许你可以帮助我...... !!

非常感谢你的帮助！

代表mvn deploy问题

您需要提供存储库地址，以便在pom.xml中部署arfifact，如下所示

<distributionManagement>
  <repository>
    <id>mycompany-repository</id>
    <name>MyCompany Repository</name>
    <url>your repository url</url>
  </repository>
</distributionManagement>

要运行maven artifact jar，需要使用mvn exec命令，然后只包含类路径中pom.xml中提到的所有jar。见下面的例子

mvn exec:java -Dexec.mainClass="de.my.path.JImp"
