Maven Run Project
提问by Verhogen
Is there a Maven "phase" or "goal" to simply execute the main method of a Java class? I have a project that I'd like to test manually by simply doing something like "mvn run".
是否有 Maven“阶段”或“目标”来简单地执行 Java 类的主要方法？我有一个项目，我想通过简单地执行“mvn run”之类的操作来手动测试。

See the exec maven plugin. You can run Java classes using:
请参阅exec maven 插件。您可以使用以下方法运行 Java 类：
mvn exec:java -Dexec.mainClass="com.example.Main" [-Dexec.args="argument1"] ...
The invocation can be as simple as mvn exec:javaif the plugin configuration is in your pom.xml. The plugin site on Mojohaus has a more detailed example.
调用可以像mvn exec:java插件配置在您的 pom.xml 中一样简单。Mojohaus 上的插件站点有一个更详细的示例。
<project>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<configuration>
<mainClass>com.example.Main</mainClass>
<arguments>
<argument>argument1</argument>
</arguments>
</configuration>
</plugin>
</plugins>
</build>
</project>

clean package exec:java -P Class_Containing_Main_Methodcommand is also an option if you have only one Main method(PSVM) in the project, with the following Maven Setup.
clean package exec:java -P Class_Containing_Main_Method如果项目中只有一个 Main 方法 (PSVM)，则命令也是一个选项，具有以下 Maven 设置。
Don't forget to mention the class in the <properties></properties>section of pom.xml:
不要忘记在以下<properties></properties>部分提及该课程pom.xml：
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.main.class>com.test.service.MainTester</java.main.class>
</properties>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<configuration>
<mainClass>${java.main.class}</mainClass>
</configuration>
</plugin>

The above mentioned answers are correct but I am simplifying it for noobs like me.Go to your project's pom file. Add a new property exec.mainClassand give its value as the class which contains your main method. For me it was DriverClassin mainpkg. Change it as per your project.
上面提到的答案是正确的，但我正在为像我这样的菜鸟简化它。转到您项目的 pom 文件。添加一个新属性exec.mainClass并将其值指定为包含您的主要方法的类。对我来说，它DriverClass在mainpkg. 根据您的项目更改它。
Having done this navigate to the folder that contains your project's pom.xmland run this on the command prompt mvn exec:java. This should call the main method.
完成此操作后，导航到包含您的项目的文件夹pom.xml并在命令提示符下运行它mvn exec:java。这应该调用 main 方法。

No need to add new plugin in pom.xml. Just run this command
无需在 pom.xml 中添加新插件。只需运行此命令
mvn org.codehaus.mojo:exec-maven-plugin:1.5.0:java -Dexec.mainClass="com.example.Main" | grep -Ev '(^\[|Download\w+:)'
See the maven exec pluginfor more usage.
有关更多用法，请参阅maven exec 插件。
