java - 启动 Maven 文件 - 无法运行

问题描述

我正在尝试启动并运行 maven，并且我完成了大部分工作（在帮助下）。目前我可以使用“运行”按钮，但我无法运行简单程序本身。我收到以下消息：

</project>

运行/调试配置：添加新配置 -> Maven -> 找到给定的项目文件夹 -> 应用/确定 *命令行：空 *配置文件：空 *解决工作区工件：未选中在此处输入图像描述

有什么简单的解决方案吗？提前致谢。

更新：将“部署”添加到命令行后：

解决方案

为了定义将执行哪个 Maven 目标，您必须在命令行部分的调试/运行配置中指定它，如下所示：

在此处输入图像描述

在您的示例中，您缺少命令行参数，这就是您收到错误的原因：

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]

编辑：

请参阅Maven 书籍的部署部分。

您需要<repositories>在您的settings.xml（不是在您的pom.xml，这很糟糕）或您的<distributionManagement>元素中定义一个元素，pom.xml如下所示：

<distributionManagement>
    <repository>
        <uniqueVersion>false</uniqueVersion>
        <id>corp1</id>
        <name>Corporate Repository</name>
        <url>file:///home/myfolder/.m2</url>
        <layout>default</layout>
    </repository>
</distributionManagement>

看到这个maven-deploy-plugin 不知道我在其中将它声明为构建插件的 pom 吗？和

未能执行目标 org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy default-deploy on project
