您需要使用 build-helper-plugin.

像这样:

 <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>build-helper-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>add-source</id>
            <phase>generate-sources</phase>
            <goals>
                <goal>add-source</goal>
            </goals>
            <configuration>
                <sources>
                    <source>${project.build.directory}/generated-sources/java/</source>
                </sources>
            </configuration>
        </execution>
    </executions>
 </plugin>

您还需要:

• 从 Eclipse Marketplace 安装Apt M2E 连接器".为此，请单击 pom.xml 的概览选项卡中的错误并选择发现".
• 确保 build-helper-maven-plugin 没有插件执行过滤器(参见 https://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html)
