Maven Profile配置activeByDefault和activeProfiles的区别 javamaven

activeByDefault 既能用在settings.xml也能用在pom.xml里
其作用maven官方文档是这么说的：

This profile will automatically be active for all builds unless another profile in the same POM is activated using one of the previously described methods.

也就是说配置了标签的profile只会在没有其他激活的profile的情况下被激活
activeProfiles 只能用在settings.xml文件
作用也看一下maven官方文档的说法：

The final piece of the settings.xml puzzle is the activeProfiles element. This contains a set of activeProfile elements, which each have a value of a profile id. Any profile id defined as an activeProfile will be active, regardless of any environment settings. If no matching profile is found nothing will happen. For example, if env-test is an activeProfile, a profile in a pom.xml (or profile.xml with a corresponding id will be active. If no such profile is found then execution will continue as normal.

在里配置的profile会无视其激活条件默认激活，如果指定的profile id不存在则忽略
总结 【Maven Profile配置activeByDefault和activeProfiles的区别】当我们需要配置一个所有环境都激活的profile，用配置，而需要配置一个其他profile都没有激活的兜底profile时，用配置
