As I thought, this is due to what is related to the user. this problem assumes that the user Jenkins is working with has never accepted the Dotfuscator user agreement. This can be solved in two ways:
Or you log in with a user who starts automatic assembly and starts the Dotfuscator GUI, and accept the license agreement
Or you can copy the following files:
C:\Users {, / }\AppData\Local\PreEmptive Solutions\Dotfuscator Professional Edition\4.0\dfusrprf.xml
C:\Users {, / }\AppData\Local\PreEmptive Solutions\Dotfuscator Professional Edition\4.0\dotfuscator.cfg
C:\ProgramData\PreEmptive Solutions\Dotfuscator Professional Edition\4.0\dotfuscator.dat
dotfuscator ( C:\Program Files (x86)\PreEmptive Solutions\Dotfuscator Professional Edition 4.13.0).
