Kri*_*fer 19 java plugins maven-2 netbeans aspectj
我正在尝试使用java 6.0将aspectj添加到maven项目中.浏览我发现2个maven插件,其中没有一个按我期望的方式工作.
第一个http://mojo.codehaus.org/aspectj-maven-plugin最初没有通过netbeans工作,因为我无法获得编译5.0或更高版本的源代码(它抱怨注释等)从命令尝试后工作和比较执行的命令的行似乎它的mavens安装目标与插件和java 5+代码不兼容,而编译目标工作正常.虽然有可能解决这个问题,但这很烦人并且让我想到了一个问题:aspectj-maven-plugin还在开发中吗?我还应该用吗?
第二个是apaches自己的,它似乎更活跃,更有可能工作.但是我找不到任何完整的例子,我无法运行它.我一直从maven得到一个例外:
java.lang.IllegalStateException: The plugin descriptor for the plugin Plugin [maven:maven-aspectj-plugin] was not found. Please verify that the plugin JAR /home/kristofer/.m2/repository/maven/maven-aspectj-plugin/4.0/maven-aspectj-plugin-4.0.jar is intact.

jar文件是完整的,并且我使用的插件版本也无关紧要,它总是抛出相同的异常.关于问题可能是什么的任何想法?
简而言之,哪个插件以及我应该如何使用它?
谢谢

这是一个适合我的设置(使用下面记录的aspectj-maven-plugin).
项目结构如下:
$ tree .
.
??? pom.xml
??? src
??? main
? ??? java
? ??? com
? ??? stackoverflow
? ??? Q3651690
? ??? App.java
? ??? DontWriteToTheConsole.aj
??? test
??? java
??? com
??? stackoverflow
??? Q3651690
??? AppTest.java
通过以下小演示方面:
public aspect DontWriteToTheConsole {
pointcut sysOutOrErrAccess() : get(* System.out) || get(* System.err);
declare error
: sysOutOrErrAccess()
: "Don't write to the console";
}

并且pom.xml配置如下:

关键部分是:
properties)properties用于配置maven-compiler-plugin的东西)第二步似乎是多余的,但是,事情就是如此.
这样,我就能够使用注释等编写代码:
