Question

我有两个Java主类，我需要在构建过程的不同部分执行。在generate-sources阶段，需要执行ALWAYS作为标准构建过程的一部分。另一个需要作为配置文件的一部分执行，但该配置文件应该在process-classes阶段结束时执行，该阶段也应包括generate-sources阶段之前的阶段。

我能够在标准构建过程的generate-sources阶段使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，当我向配置文件添加同一插件的第二个实例时，在构建过程中不再调用定义为标准构建的一部分的插件，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内容：mvn process-classes -PinitSchema。我的配置有什么问题？我期待两个插件在各自的阶段执行。

澄清：第一个exec-maven-plugin生成源，第二个初始化我的数据库架构。

Answer 1

给两个执行块一个不同的id，因为现在它们都使用默认id，因此一个将覆盖另一个。

在POM中定义的2个exec-maven-plugin - 无法正常工作
