1. Offline installation and online installation
Because offline installation is used, only offline methods are known, so only offline installation methods can be recorded
I found a lot of examples on the Internet but failed to install them successfully. Later, I tried to use the method of integrating plug-ins (spring and hibernate are also implemented in this way)
Download plug-ins online: http://www.activiti.org/designer/archived/
Unzip and open eclipse --help--install new software--add --local--decompressed file
select all---next--
Then restart eclipse ---new --osther--activiti--
