How to add context menu adds-on in Spring Tool Suite

Flow
1

I am a new babe for Spring and Vaadin.
I have created a spring boot project with vaadin by using Spring Tool Suite.
I need to use tree with context menu.

The default context menu for tree works for most of the part, but it miss the capability of submenu.

So I am trying to use the ContextMenu adds-on.
I followed the instruction and added the repository in my project, but I can’t find
Peter’s 4.5 ContextMenu adds on at all from pom.xml
If I added Peter’s ContextMenu.jar to my project, the menu won’t be displayed.

If I added Vaadin’s 0.73 ContextMenu, I can’t get it run, following is the stack trace.

Please help me, thank you in advance!

Sounds like you may not have the dependency correctly in your pom.xml. Can you share the dependencies section of your pom file?

I removed the adds-on directory in .m2, now I can run.

But I can’t get the click event of the tree node where the right click for the context menu.

Ok, good. Sounds like the first issue you had was Maven/permission related.

How are you registering the click listener to the Tree?

Tree myTree = new Tree();
ContextMenu contextMenu = new ContextMenu(myTree ,true);
contextMenu.addContextMenuOpenListener(event → {
Object target = event.getSourceComponent();
if(target==null)
target = event.getContextClickEvent().getSource();
if(target == null)
{
Notification.show(“No target!”);
return;
}
Notification.show(target .getClass().getSimpleName(),
Notification.Type.HUMANIZED_MESSAGE);
});

The menu won’t show up, I added itemClickListner to tree, it didn’t help either.
contextMenu.addItem(“Open”, e → {
Notification.show(“Clicked Open”);
});
contextMenu.addSeparator();
contextMenu.addItem(“Delete”, e->
{
Notification.show(“Picked Delete”);
});

myTree.addItemClickListener(new ItemClickEvent.ItemClickListener() {
public void itemClick(ItemClickEvent event) {
if(event.getButton() == MouseButton.RIGHT) {
contextMenu.open(event.getClientX(), event.getClientY());
}
}
});

Please advise, thank you!
