Here is a list of all accepted GroIMP command line arguments (the are given after the .jar):

• –project-tree this argument is used when GroIMP is run in Eclipse, it tells GroIMP to load classes under the local /PLUGIN/target/classes/ repositories where PLUGIN is the name of each directories at the root of GroIMP. This path is different when GroIMP is run after packaging. By default GroIMP load classes in ./plugins/PLUGIN/PLUGIN.jar where PLUGIN is the name of each plugins.
• -headless this argument start GroIMP headless, i.e. without a graphical interface. Usually you also define the project to open as an argument (see 4.).
• -a api this argument defines which application will be started (current available application: imp, cli, api). By default GroIMP starts with imp.
• -p /path/to/a/directory/ link a directory to the list of loaded plugins.
• -t config file
• ' ' path/to/a/model.gsz this argument requires to be used last. It gives a model to be opened after start.
