### 解决方案
当遇到 `NoGoalSpecifiedException` 错误时,这意味着 Maven 不知道要执行的操作,因为它没有接收到任何构建目标或生命周期阶段的指令。以下是解决问题的方法:
#### 1. 明确指定构建目标或生命周期阶段
可以通过命令行显式调用一个生命周期阶段或特定的目标来解决此问题。例如,可以使用以下命令之一启动构建过程:
```bash
mvn clean install
```
这条命令会清理之前的构建产物并安装新的构件到本地仓库[^2]。
如果只需要验证项目的可编译性而不生成最终工件,则可以选择更轻量级的选项:
```bash
mvn compile
```
#### 2. 配置默认目标(可选)
为了简化流程,在 `pom.xml` 文件中配置 `<default Goal>` 或者绑定某些插件到生命周期阶段也可以避免手动输入目标名称的情况。例如:
```xml
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M5</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>test</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
```
通过这种方式,即使不提供额外参数,默认也会触发测试阶段的任务[^3]。
#### 3. 使用IDE内置功能辅助开发调试
对于日常编码工作来说,借助像Eclipse这样的集成环境能够减少很多繁琐的手动操作。比如可以直接右键点击项目->Run As -> Maven Build... 来快速设置好相应的 goals 和 profiles 而无需每次都回到终端界面去敲完整的 mvn 命令串[^1]。

### 示例代码片段展示如何定义自定义 goal 的 pom.xml 设置
下面是一个简单的例子,展示了怎样把单元测试纳入常规打包过程中的一部分:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<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">
...
<build>
<!-- 插入此处 -->
<plugins>
<plugin>
