I'm just starting playing around with the plugin SDK for IntelliJ IDEA. However I already have some trouble with the first step.

I'd like to place an action in the lower status bar, next to the Git actions.

How can I place that action there?

This type of UI is called EditorBasedWidget. If you like to explore how it works in git4idea plugin, I can suggest you to start with GitBranchWidget and DvcsStatusWidget classes.

Here is the code for the simplest example:

MyWidget.java

public class MyWidget extends EditorBasedWidget 
 public MyWidget(@NotNull Project project) 
 super(project);
 

 @NotNull
 @Override
 public String ID() 
 return "MyWidget";
 

 @Nullable
 @Override
 public WidgetPresentation getPresentation(@NotNull PlatformType type) 
 return new MyPresentation();
 

MyPresentation.java

public class MyPresentation implements StatusBarWidget.MultipleTextValuesPresentation 
 @Nullable("null means the widget is unable to show the popup")
 @Override
 public ListPopup getPopupStep() 
 return null;
 

 @Nullable
 @Override
 public String getSelectedValue() 
 return "Selected value";
 

 @NotNull
 @Override
 public String getMaxValue() 
 return "Max value";
 

 @Nullable
 @Override
 public String getTooltipText() 
 return "Tooltip text";
 

 @Nullable
 @Override
 public Consumer<MouseEvent> getClickConsumer() 
 return null;
 

Somewhere, for example in ProjectComponent

ApplicationManager.getApplication().invokeLater(() -> 
 StatusBar statusBar = WindowManager.getInstance().getStatusBar(myProject);
 if (statusBar != null) 
 statusBar.addWidget(new MyWidget(myProject));
 
);

And here is the result:
