maven - 2 POM 中定义的 exec-maven-plugin - 不工作

Question

我有两个 Java 主类，需要在构建过程的不同部分执行。在 generate-sources 阶段，需要始终作为我的标准构建过程的一部分执行。另一个需要作为配置文件的一部分执行，但该配置文件应在 process-classes 阶段结束时执行，该阶段还应包括 generate-sources 阶段在此之前。

我能够在标准构建过程的 generate-sources 阶段让第一个插件正常工作:

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <version>1.2.1</version>
                <executions>
                    <execution>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>java</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <mainClass>com.example.MySourceGenerator</mainClass>
                </configuration>
            </plugin>

但是，当我将同一插件的第二个实例添加到配置文件时，在我的构建过程中不再调用定义为标准构建一部分的插件，从而导致编译错误。这是配置文件中的配置:

<profiles>
        <profile>
            <id>initSchema</id>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.codehaus.mojo</groupId>
                        <artifactId>exec-maven-plugin</artifactId>
                        <version>1.2.1</version>
                        <executions>
                            <execution>
                                <phase>process-classes</phase>
                                <goals>
                                    <goal>java</goal>
                                </goals>
                            </execution>
                        </executions>
                        <configuration>
                            <mainClass>com.example.SomeOtherClass</mainClass>
                        </configuration>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>

这是我在命令行上运行的:mvn process-classes -PinitSchema。我的配置有什么问题？我希望这两个插件在各自的阶段执行。

澄清一下:第一个 exec-maven-plugin 生成源，第二个初始化我的数据库模式。

给两个执行 block 一个不同的 id，因为现在它们都使用默认 id，所以一个会覆盖另一个。
