Bug: Source Action -> "Generate Constructors..." only available after at least one class member was added

[Eden33]

Environment:

• VS Code Version: 1.89.1
• Extension Version: v0.26.0
• JDK Type & Version: Java version: 17.0.9, vendor: Oracle Corporation
• OS Type & Version: Windows 11

Step to Reproduce:

Expected Behavior:
The "Generate Constructors ..." option should instantly be available without the requirement to add a class member.

Actual Behavior:
The "Generate Constructors ..." option becomes available earliest when a single class member was added.

Additional comment:
This behaviour is also available in IntelliJ and makes sense.

Hi Eduard Gopp (@Eden33), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

It looks like the JDT LS only offers “Generate Constructors…” when there are fields to initialize—because an empty (no-arg) constructor is implicit, the action isn’t shown for a totally empty class.

Workarounds & suggestions:

• Manually write the default constructor:

  public MyClass() {
      super();
  }

• If you’d like a dedicated “Generate default constructor” action even on empty classes, please file an enhancement against eclipse.jdt.ls:
  https://github.com/eclipse/eclipse.jdt.ls/issues/new?template=feature_request.md
