20181203 有新的发现，这个qaplug总和了checkstyle，findbugs，pmd，hammurapi，我之前都是5个全装，今天经过测试发现不装qaplug-findbugs就正常，好像就findbugs组件出了问题
as已经发展到3.2.1了，以前在2.2用过qaplug去检测分析代码
现在公司有需求，让我再看一下，好的话公司里推广
然后就发现as3.0以上的，新建的项目可以用qaplug，现有的项目都不行
我把现有项目的gradle降级到2.3.3，然后用as233去加载现有项目，然后用qaplug就可以了
as3.0+一般会报一个PsiIdentifierImpl的错误，使用qaplug后，那个result窗口不会弹出来
而是弹messages窗口，然后在as右下角有一个红底白色感叹号，点一下会有个ide fatal error
as3.1.2具体报错信息如下：
