【问题描述】：

我正在尝试构建这个 maven 项目：

在这个 maven 中：

我发现了一些关于它的问题：

  1. No goals have been specified for this build.
  2. maven - j2objc - No goals have been specified for this build
  3. No goals have been specified for this build
  4. Maven how to find out what settings.xml is used (Ubuntu)
  5. How to fix this Build Path Error?
  6. How to fix this maven warning on Eclipse: "There is no schema defined for this pom.xml"

他们说我需要设定一个目标：

  <goals>
    <goal>exploded</goal>
  </goals>

但是不知道怎么放到上面的配置文件里。这是运行初始 pom.xml 时的完整日志输出：

我不想从 Eclipse 中运行它。我宁愿只调用命令行mvn，就像我目前正在做的那样。

【问题讨论】：

    标签： java maven


    【解决方案1】：

    可以在 pom.xml 的 build-plugins-plugin 部分中指定目标，具体取决于您希望应用程序发生的情况。

    例如如果您想执行它，您可以按照问题How do I execute a program using Maven?中描述的步骤进行操作。

    我认为您不能仅使用 mvn 来做到这一点，但您需要指定会发生什么（例如 mvn package 或 mvn install）

    您可以在Introduction to the Build Lifecycle 上阅读有关目标和阶段的更多信息。

    【讨论】：

    • 通过将“install”添加到我的构建部分，我能够让 mvn install 成为我的默认设置。现在只需运行 mvn 即可安装。
    • 我发现这对我有用。在“编辑配置”对话框窗口中，为“命令行”选择 spring-boot:run，单击应用并确定。那么你应该很高兴。
    【解决方案2】：

    在运行/调试配置的命令行字段中输入所需的生命周期事件。 对我来说，我想运行这个项目，所以我使用了 spring-boot:run

    它对我有用

    Maven life cycle references

    【讨论】：

    • 感谢 Buddy，它的作用就像魅力一样，我很沮丧。
    【解决方案3】：

    在 cmd 中运行以下命令： mvn clean

    【讨论】：

      【解决方案4】：

      对我来说，以下解决方案有效。 转到终端并运行“mvn clean install”

      【讨论】：

      【解决方案5】：

      如果您正在使用 Jenkins + maven，请转到 job->build-> 并添加目标和选项：

      clean install -Denvironment="$"environment

      【讨论】：

        【解决方案6】：

        为了有一个清晰的例子，您可以使用 exec-maven-plugin

        来运行带有 mvn package exec:java 的应用程序 
        <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.2.1</version>
    <executions>
        <execution>
            <goals>
                <goal>java</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <mainClass>com.path.to.MainFile</mainClass>
    </configuration>
</plugin>
        1. com.path.to.MainFile 文件将位于 /src/main/java/com/path/to/MainFile.java
