在intellij idea中为aspectj weaver设置编译级别

Question

我在项目中添加了简单的注解驱动方面，但 IntelliJ 无法编译：

annotation type patterns are only supported at Java 5 compliance level or above

请告知，应该在哪里配置编译级别（在项目设置中，整个项目和所有模块都设置为 Java 6），在 settings->aspectj weaver 中只能启用 weaver 并查看方面列表。

UPD 问题与 OpenJDK 有关，因为 aspectJ weaver 插件无法正确识别它的版本。补丁已提交给维护者。

Answer 1

试试

source="1.5"

在 build.xml 中插入 iajc 任务

Answer 2

我通过升级 aspectjweaver jar 解决了现有合规级别的问题。使用aspectjweaver-1.7.3.jar
