Java Maven的问题

当我想在我的项目中运行“mvn部署”时，我遇到以下错误：

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

我的POM文件如下所示：

<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">
    <modelVersion>4.0.0</modelVersion>
    <groupId>JImp</groupId>
    <artifactId>JImp</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <build>
        <sourceDirectory>src</sourceDirectory>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
    <dependencies>
        <dependency>
            <groupId>org.apache.xmlbeans</groupId>
            <artifactId>xmlbeans</artifactId>
            <version>2.6.0</version>
        </dependency>
        <dependency>
            ....
        </dependency>
    </dependencies>
</project>

然后执行我的jar

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

他抛出了一个ClassNotFoundException，因为他找不到我自己库的类。。但此库已添加到本地存储库和我的POM文件中的Dependency..：/

也许你能帮我

我非常感谢你的帮助

对于

mvn部署问题

您需要在pom.xml中提供要部署arfifact的存储库地址，如下所示

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

我发现：“Maven将首先尝试使用指定工件的本地副本。如果本地存储库中不存在该工件，它将尝试从远程存储库下载”（）当我想使用mvn deploy时，为什么我必须定义一个存储库？调用mvn包就足够了，还是我必须通过调用mvn deploy
mvn deploy
命令来运行整个默认生命周期（验证、编译、测试、打包、集成测试、验证、安装、部署）来将您的工件上传到远程存储库。如果您只想添加到本地存储库中，那么
mvn安装
就可以了。对于第二个问题，它作为生命周期运行，所以当您在生命周期阶段执行时，比如说
包
，在它自动执行之前的所有阶段。非常感谢您的帮助！！！关于我的第二个问题：默认情况下应该调用哪个阶段？我知道，这取决于我想要什么，但是“集成测试”和“验证”阶段对查找错误或类似的东西有用吗？我认为我不需要“安装”和“部署”阶段，因为我不在其他项目（本地和远程存储库）中使用我的工件
<distributionManagement>
  <repository>
    <id>mycompany-repository</id>
    <name>MyCompany Repository</name>
    <url>your repository url</url>
  </repository>
</distributionManagement>

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