java - maven:pom中多个配置文件的顺序

Question

我有一个定义了 3 个配置文件的 pom。 我想要:

1. 始终在所有其他配置文件之前运行“生成”配置文件(如果需要)

2. 基于例如属性运行 dev/normal 配置文件 pom 片段:

                       </includes>
                   </configuration>
               </plugin>
           </plugins>
       </build>
   </profile>
   

问题是，在干净的编译中，它每第二次就会工作一次。 我启用了 -X 调试并比较了输出。 - 是失败的，+ 是有效的。

当我运行 help:active-profile 时

1. 成功后显示: 以下配置文件处于 Activity 状态:

   • 正常(来源:pom)
   • nexus(来源:settings.xml)

2. 失败后显示: 以下配置文件处于 Activity 状态:

   • 生成轴 stub (来源:pom)
   • 正常(来源:pom)
   • nexus(来源:settings.xml)

如果我手动清理它然后编译 - 它始终有效。但为什么它并不总是适用于干净编译呢？ 谢谢!

Answer 1

因为配置文件只被评估一次。所以问题不在于干净编译，而在于启动Maven时文件夹target/generated-sources是否存在。

如果存在，clean 编译 必须失败，因为 clean 会删除该文件夹，但 Maven 不再关心。
