-optimizationpasses 5

#Do not generate mixed case class names when confusing, that is, all lowercase
-dontusemixedcaseclassnames

#Specifies that classes that do not ignore non-public libraries
-dontskipnonpubliclibraryclasses

#Specifies that library class members (fields and methods) visible to the package are not ignored.

#The method names in the confusion class are also confused, and the unique confusion name is generated for the class to be confused
-useuniqueclassmembernames

#Turn off pre validation

#Specify optimization algorithm
