jira keygen
转载来源不明，仅供大家了解其中的java相关的知识
JIRA可真是个好东西啊,自定义能力超强,虽然主要是用来做bug跟踪管理的,但是很容易的就可以改造成项目管理系统.只可惜是要收费的,为了使用它,sorry啊,只好下载了一个注册机.不过下载的注册机是JIRA3.0版的,现在的JIRA已经出到3.1版了.试了一下发现注册机不行用.几乎放弃了就,但是仔细分析了一下JIRA的包的结构,发现注册机不行用很可能是因为3.1版的包结构改变了,破解需要的那个licence包的位置变掉了.于是抱着侥幸心理把下载的注册机keygen.class反编译了一下,结果发现注册机没有被混淆过,很容易就看到了所有的代码,于是就将注册机import的包名改了一下,重新编译,呃,可以用了,真是对不起,做了错事了.
