Description

Run and Debug now share a single launch configuration.

If you are coming from an older Espressif-IDE version that had two configs — one for Run (flash) and one for Debug — you can keep using the old Run config as-is. Select it in the launch bar, switch the mode to Debug, and start debugging. You do not have to open the configuration editor first, and you do not have to click Restore defaults. Any debug settings that were never stored on that Run config are filled in at launch with the plugin defaults.

In the editor, empty debug fields are allowed (they show “keep empty for default”). Each Espressif tab also has a Restore defaults button if you want to write the defaults into the file.

Fixes # (IEP-XXX)

Type of change

  • New feature (non-breaking change which adds functionality)
  • This change requires a documentation update

How has this been tested?

  • LaunchAttributesTest (JUnit)
  • Manual: take an old Run config (from before unification), switch the launch bar to Debug, and start a session without opening the editor or clicking Restore defaults
  • Manual: open the editor, leave debug fields empty, save, and debug — plugin defaults are used
  • Manual: Restore defaults on Main, Debugger, Startup, SVD, and Run Main
  • Debug session: breakpoints, step, halt/resume, OpenOCD console
  • Heap tracing (start/stop from breakpoint, dump file appears)
  • Heap dump analysis
  • Application-level tracing
  • Flash before debug / skip flash, verbose OpenOCD output
  • JTAG flash and serial monitor after flash (Run mode on the same config)

Test Configuration:

  • ESP-IDF Version: v5.4
  • OS (Windows,Linux and macOS): Windows

Dependent components impacted by this PR:

  • com.espressif.idf.core

Checklist

  • PR Self Reviewed
  • Applied Code formatting
  • Added Documentation
  • Added Unit Test
  • Verified on all platforms - Windows,Linux and macOS

📝 Walkthrough

Walkthrough

The PR adds an Eclipse launch-defaults extension point, implements OpenOCD default injection, and applies defaults during launch configuration creation and execution. It also updates launch delegates, launch tabs, run handling, project wizard setup, and user documentation.

Changes

Launch Defaults and Unified Debug Flow

Layer / File(s) Summary
Extension point and attribute utilities
bundles/com.espressif.idf.core/plugin.xml, bundles/com.espressif.idf.core/schema/..., bundles/com.espressif.idf.core/src/com/espressif/idf/core/util/*, tests/com.espressif.idf.core.test/src/.../LaunchAttributesTest.java
Defines the launch-defaults contract. Adds shared attribute read/write helpers and tests.
OpenOCD defaults integration
bundles/com.espressif.idf.debug.gdbjtag.openocd/src/.../preferences/*, bundles/com.espressif.idf.debug.gdbjtag.openocd/src/.../{Configuration.java,dsf/*}
Registers OpenOCDDefaultsInjector, applies missing or empty defaults, and uses resolved values during launch setup.
Launch tab defaults and persistence
bundles/com.espressif.idf.debug.gdbjtag.openocd/src/.../ui/*, bundles/com.espressif.idf.launch.serial.ui/src/.../CMakeMainTab2.java
Adds empty-default hints, restore-default controls, shared attribute persistence, and revised validation.
Shared SWT controls
bundles/com.espressif.idf.swt.custom/src/com/espressif/idf/swt/*
Adds reusable restore-default controls, localized messages, and TextWithButton.setMessage.
Unified launch routing
bundles/com.espressif.idf.debug.gdbjtag.openocd/plugin.xml, bundles/com.espressif.idf.launch.serial.core/plugin.xml, bundles/com.espressif.idf.launch.serial.ui/plugin.xml, bundles/com.espressif.idf.ui/src/...
Adds unified debug registration, associates serial tabs with the serial delegate, simplifies direct launch handling, and removes wizard-based debug configuration creation.
Documentation and cleanup
docs/en/openocddebugging.rst, docs/zh_CN/openocddebugging.rst, bundles/com.espressif.idf.core/src/.../IDFEnvironmentVariables.java
Documents empty fields and restore-default controls. Adds whitespace-only cleanup.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to a902b

The unified launch and debug configuration can fail to save certain local-server setups or abort launch when an older configuration contains an invalid TCL port value. These bounded compatibility issues should be addressed or explicitly accepted before merging.

In `@bundles/com.espressif.idf.core/schema/launchDefaultsContributor.exsd`:
- Around line 8-10: The schema's <documentation> placeholders in
launchDefaultsContributor.exsd must be replaced with concrete descriptions for
the public extension contract: locate each <documentation> element inside the
extension point (the current placeholder text "[Enter description of this
extension point.]") and replace it with a clear summary of the extension's
purpose, the contract contributors must implement (expected XML
attributes/elements or extension IDs), required/optional behavior, and a short
example or usage note so implementers know how to provide launch defaults;
update all occurrences (the five placeholder documentation nodes) to use this
concrete content so contributor authors can implement correctly.

In
`@bundles/com.espressif.idf.launch.serial.core/src/com/espressif/idf/launch/serial/core/IDFCoreLaunchConfigProvider.java`:
- Around line 85-98: The loop that invokes
element.createExecutableExtension("class") and then calls
ILaunchDefaultsContributor.applyDefaults(workingCopy) must be hardened so
unchecked exceptions from contributors don't abort config creation; wrap the
contributor execution (the createExecutableExtension call and the applyDefaults
invocation on the ILaunchDefaultsContributor) in a broader try/catch that
catches Exception, and in that catch log the contributor identity (e.g.,
element.getAttribute("class") or element.toString()) along with the exception
via Logger.log so failures are isolated and recorded; keep the existing
CoreException handling but add the generic Exception handler around the
contributor invocation path.

To reproduce:
OS: Windows 11
ESP-IDF: any

Create project -> build + flash -> create NEW Debug config -> start Debug: error :
Screenshot 2026-08-31 at 12 11 36

because new Debug config does have C/C++ Application field empty:

Thanks for the PR, overall LGTM. Also add regression tests that launch a minimal legacy run configuration in debug mode and cover all migration scenarios..

Was this extension point introduced to avoid cyclical dependecy among plugins and do you see other use cases?

Yes. The extension point exists so OpenOCD defaults can be applied from bundles that must not depend on the OpenOCD plugin.

@sigmaaa @kolipakakondal hi !
Tested under:
OS: Windows 11
ESP-IDF: v6.0.2

New ESP-IDF project creation and unified launch configuration ✅
Flash over UART / JTAG ✅
Debug over JTAG/OpenOCD ✅
Breakpoint, Continue, Step Over, and clean debug termination ✅
Switching between Run → Debug → Run using the same configuration, with no duplicates or mess in config ✅
Updated OpenOCD preferences correctly applied to a newly created configuration ✅
Existing/legacy project still runs and debugs correctly (keep old Debug config, update Launch Config) ✅
Creation of new Launch Config / Debug Config works as expected ✅

LGTM

@sigmaaa hi !
Tested under:
OS: Linux Ubuntu

the reason "Flash test" is constantly failing is because whenever you click Gear icon to Edit Configuration, it does add (1) to the name and silently adding this config to the list, so the test run Flash using right click on the project in the Project Explorer - "Run As -> select run config -> run" and select the original one(without (1)), there is no selected port visible.
