如何配置pom.xml以在1 Maven项目中运行2个java主管

Question

我有一个Maven项目,它在src文件夹的一个包中有2个主电源(MyTestApp_A和MyTestApp_B).

如果我打开它们并单击运行按钮,我可以在Eclipse中运行这些"main"类.但是,Eclipse有问题,因此我实际上需要使用Maven在命令行上运行这两个类.

我之前从未使用过Maven,但在寻求帮助并进行一些研究后,我明白我必须更改pom.xml文件.

因此,我已成功更改了我的pom.xml文件,以使用以下命令运行其中一个应用程序mvn exec:java -Dexec.mainClass="servers.MyTestApp_B":

    <plugins>
        <!-- Allows the example to be run via 'mvn compile exec:java' -->
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.2.1</version>

            <configuration>
                <mainClass>servers.MyTestApp_A</mainClass>
                <includePluginDependencies>false</includePluginDependencies>
            </configuration>


        </plugin>

    </plugins>

很高兴能够运行MyTestApp_A,我尝试添加另一个配置部件来运行MyTestApp_B:

    <plugins>
        <!-- Allows the example to be run via 'mvn compile exec:java' -->
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.2.1</version>

            <configuration>
                <mainClass>servers.MyTestApp_A</mainClass>
                <includePluginDependencies>false</includePluginDependencies>
            </configuration>
            <configuration>
                <mainClass>servers.MyTestApp_B</mainClass>
                <includePluginDependencies>false</includePluginDependencies>
            </configuration>

        </plugin>

    </plugins>

但是,此文件格式不正确.显然我不允许<configuration>在同一个pom.xml文件中有2个标签.

那么,我如何使用Maven执行MyTestApp_A和MyTestApp_B？如何配置pom.xml文件？

尝试对要执行的每个主类使用执行:

<plugins>
    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>1.2.1</version>
        <executions>
            <execution>
                <id>MyTestApp_A</id>
                <goals>
                    <goal>java</goal>
                </goals>
                <configuration>
                    <mainClass>servers.MyTestApp_A</mainClass>
                    <includePluginDependencies>false</includePluginDependencies>
                </configuration>
            </execution>
            <execution>
                <id>MyTestApp_B</id>
                <goals>
                    <goal>java</goal>
                </goals>
                <configuration>
                    <mainClass>servers.MyTestApp_B</mainClass>
                    <includePluginDependencies>false</includePluginDependencies>
                </configuration>
            </execution>
        </executions>
    </plugin>
</plugins>
