oh sorry didn t notice that at the top of the paste

bbaldino · Answer

i don t seem to get an error in a scratch file could it be something about how you have them implemented that isn t in the paste

Smallville7123 · Answer

ill attempt to make a minimal example

Smallville7123 · Answer

minimal example a build gradle kts ``` import java io File import java io RandomAccessFile import java nio ByteBuffer import java nio channels FileChannel fun fileToByteBuffer f File ByteBuffer val file = RandomAccessFile f r val fileChannel = file getChannel var i = 0 var buffer = ByteBuffer allocate fileChannel size toInt fileChannel read buffer buffer flip return buffer val filetmp = sda3 partition resize to size class lexer stm ByteBuffer delimiter String val f = stm val delimiters = delimiter fun clone val ll = lexer fileToByteBuffer File filetmp none tasks register test val lex = lexer fileToByteBuffer File filetmp none println cloning lex clone println clone sucesfull ``` app build gradle ``` apply from a build gradle kts preBuild dependsOn test ```

i just pasted it into a quick kotlin file and changed the task to a main i get a filenotfoundexception since i don t have that file but no complaint about the instantiation
