英文:
Unknown lifecycle phase on Maven
问题
我尝试在另一台笔记本电脑上重新运行我的Maven项目，文件完全相同。我使用以下命令进行编译：
mvn exec:java -Dexec.mainClass=id.tumbs.App
这在我进行项目的那台笔记本电脑上运行正常，但在另一台笔记本电脑上报错。错误代码如下：
[ERROR] 未知的生命周期阶段 ".mainClass=id.tumbs.App"。您必须指定一个有效的生命周期阶段或目标，格式为 <plugin-prefix>:<goal> 或 <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>。可用的生命周期阶段包括：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。-> [帮助 1]

I tried to re-run my maven project in another laptop with the exact same file. I compiled it with this command:
mvn exec:java -Dexec.mainClass=id.tumbs.App
This works on the laptop I was doing the project for, while throwing out an error on another laptop. The error code is

尝试将主类用双引号括起来：
```bash
mvn exec:java -Dexec.mainClass="id.tumbs.App"
类似地，您可以使用 -Dexec.args="arg0 arg1" 来传递参数。
如果您在Windows上操作，需要为 exec.mainClass 和 exec.args 应用引号：
mvn exec:java -D"exec.mainClass"="id.tumbs.App"
如果您需要频繁执行此操作，您可以将参数添加到 pom.xml 文件中，如下所示：
<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>id.tumbs.App</mainClass>
<arguments>
<argument>arg0</argument>
<argument>arg1</argument>
</arguments>
</configuration>
</plugin>
如果您想了解更多关于此事的详细信息，请查看 maven-exec-plugin。
英文:
Try specifying your main class in double quotes:
mvn exec:java -Dexec.mainClass="id.tumbs.App"
Similarly, you can use -Dexec.args="arg0 arg1" to pass arguments.
If you're on Windows, you need to apply quotes for exec.mainClass and exec.args:
mvn exec:java -D"exec.mainClass"="id.tumbs.App"
If you're doing this more frequently, you can add the parameters into the pom.xml like this:
<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>id.tumbs.App</mainClass>
<arguments>
<argument>arg0</argument>
<argument>arg1</argument>
</arguments>
</configuration>
</plugin>
