Question

是否可以仅使用aspectj-maven-plugin编译带有软化异常（例如：declare soft: Exception : execution(* *.*());）方面的项目？我无法处理它...我仍然遇到编译错误

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

所以编译时没有考虑方面的问题。

我正在使用此命令编译：

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>

                <aspectDirectory>src/main/aspect</aspectDirectory>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>compile</goal>
                        <goal>test-compile</goal>
                    </goals>
                </execution>

我做错了什么？

Answer 1

实际上我认为Maven编译器插件3.0和3.1中存在一个错误，因为对我来说它适用于插件版本2.5.1。似乎增量编译被破坏或者相应的开关useIncrementalCompilation在其含义中以某种方式被意外颠倒，因为它是在3.1中引入的。有趣的是，将其值设置为false可以解决我的情况。降级到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链接的问题所述。
