IDEA版本: 2017.1.1 GsonFormat版本: 1.5.0

最简单的json，也会报错。

{
    "key":"value"
}

+1 我还以为就我有问题，还给作者发了邮件

@Bpazy @ghoslin01 我也出现和你们一样的问题，看了下源代码，发现是包名的问题，如果你的类没有包名就会出这个错，有包名就不会出错。

public static String getPackage(PsiClass cls) {
        if (cls.getQualifiedName() == null) {
            return null;
        }
        int i = cls.getQualifiedName().lastIndexOf(".");
        return cls.getQualifiedName().substring(0, i);
    }

修改成

public static String getPackage(PsiClass cls) {
        if (cls.getQualifiedName() == null) {
            return null;
        }
        int i = cls.getQualifiedName().lastIndexOf(".");
        if(i>-1){
          return cls.getQualifiedName().substring(0, i);
       }else{
          return "";
      }

    }

不知道是不是就能解决呢
