aspectj-maven-plugin，声明软件如何编译

Question

是否可以只使用aspectj plugin编译带有软异常(例如：declare soft: Exception : execution(* *.*());)的项目？我无法处理..。我仍然收到编译错误

unreported exception Exception; must be caught or declared to be thrown

因此，它是在没有考虑到方面的情况下编译的。

我使用这个命令编译：

mvn clean aspectj:compile

我的pom.xml是：

<project>
<modelVersion>4.0.0</modelVersion>
<groupId>pl.group.id</groupId>
<artifactId>aop</artifactId>
<version>1.0.0</version>

<dependencies>

我做错了什么？

Answer 1

实际上，我认为Maven Compiler插件3.0和3.1中存在一个bug，因为对我来说，它适用于插件2.5.1版本。似乎增量编译中断了，或者对应的开关useIncrementalCompilation在其含义上被意外地颠倒了，因为它是在3.1中引入的。有趣的是，将它的值设置为false为我解决了这个问题。将评级下调至2.5.1也是如此。在这两种情况下，我都需要将AspectJ Maven插件的阶段更改为process-sources，如用户@Gus链接的问题中所描述的那样。
