如何使用Maven从特定包中执行java类？

标签： java eclipse maven

在eclipse中有一个带有几个包的项目并转换为maven。 如何从特定包中执行一个java类，java类共享来自同一包中的其他java类的方法。

例如：

Selenium_Test
   |
 src/test/java
      |
      package1
         | (Test1.class, Utility.class, date.class.etc...)
      package2
      package3

我想要的是执行Test1.java。 我尝试了这个命令mvn -Dtest=Test1，它执行Test1但我找不到Utility.class，Date.class

错误是：

mvn -Dtest=Test1 test

您可以将Exec Maven Plugin用于此目的。

这是你在项目pom中激活插件的方法：

<project>
  ...
  <build>
    <!-- To define the plugin version in your parent POM -->
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <version>1.3.2</version>
        </plugin>
        ...
      </plugins>
    </pluginManagement>
    <!-- To use the plugin goals in your POM or parent POM -->
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>1.3.2</version>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

然后，您可以使用以下目标致电您的课程：

mvn exec:java -Dexec.mainClass="com.example.Main"

编写测试代码时，请考虑使用JUnit或TestNG框架和Maven Surefire Plugin来构建测试代码。
