Question

我有一个具有两个主要类的maven项目，并希望像这样通过命令单独运行每个类：

function reducer2(state, action){
  switch(action.type) {
    case "RESET_STATE":
      return {
        someCount: 0,
        someArray: [],
        someBoolean: false,
      };
  }
}

我尝试将绝对路径添加到execute标签中的两个类，但是这样做不允许我单独运行它们。
例如，无论我在运行jar时指向哪个主类，RunApp1都将始终运行。我很确定这是我忽略的一个小问题。

我的pom.xml：

java -jar appName.jar -cp com.green.RunApp1
java -jar appName.jar -cp com.blue.RunApp2

Answer 1

您需要在该部分中使用不同的ID指定主要类。像这样：

<execution>
    <id>main1</id>
    <configuration>
        <mainClass>Main1</mainClass>
    </configuration>
</execution>
<execution>
    <id>main2</id>
    <configuration>
        <mainClass>Main2</mainClass>
    </configuration>
</execution>

Answer 2

我能够通过制作两个不同的配置文件来使其工作，但是我必须为它的工作构建两个不同的jar，这违背了目的。这是我的新pom.xml

这里是我如何构建和运行它们的方法。

mvn clean package -DskipTests  -P Tiger
java -jar -Dspring.profiles.active=Tiger target/amazingApp.jar
mvn clean package -DskipTests  -P Lion
java -jar -Dspring.profiles.active=Lion target/amazingApp.jar

这不是我所期望的。相反，我想建立一个jar，然后在单个jar中的配置文件之间切换。有人可以指出我正确的方向吗？
