-## Key Benefits for Copilot Agents -1. **Reduced Timeout Risk**: Builds should complete well under 5 minutes -2. **Consistent Environment**: Same configuration across all development environments -3. **Cached Dependencies**: Persistent cache reduces repeated downloads -4. **Optimized JVM Settings**: Better memory management and parallel processing - -## Implementation Details -- **Gradle Cache**: Mounted as persistent volume for cross-session reuse -- **Parallel Processing**: Enabled for faster multi-module builds -- **Memory Optimization**: 4GB heap with optimized metaspace -- **Fallback Strategy**: Graceful degradation if dependency resolution fails - -This configuration implements the GitHub Copilot agent optimization strategy described in the official documentation for preinstalling tools and dependencies in the development environment. \ No newline at end of file diff --git a/.devcontainer/README.md b/.devcontainer/README.md index 0c2214817b6c..ee9c76413c56 100644 --- a/.devcontainer/README.md +++ b/.devcontainer/README.md @@ -18,10 +18,10 @@ This directory contains the development container configuration for the OpenTele ## How it works 1. **Base Image**: Uses Microsoft's Java dev container with OpenJDK 21 -2. **Pre-installation**: Downloads Gradle dependencies during container build +2. **Post-creation Setup**: Downloads Gradle dependencies during container startup 3. **Optimization**: Sets up Gradle daemon with optimized JVM settings 4. **Node.js**: Installs Node.js 16 and pnpm for Vaadin tests -5. **Post-setup**: Runs additional optimization after container creation +5. **Dependency Caching**: Attempts to resolve and cache dependencies after container creation ## Usage From a23105b832f693e513b31b31e96d0190ee0d3d59 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Wed, 16 Jul 2025 21:59:15 +0000 Subject: [PATCH 07/15] Address code review feedback: simplify dev container config Co-authored-by: trask <218610+trask@users.noreply.github.com> --- .devcontainer/Dockerfile | 9 +-------- .devcontainer/README.md | 11 +---------- .devcontainer/devcontainer.json | 2 +- .devcontainer/post-create.sh | 4 ++++ 4 files changed, 7 insertions(+), 19 deletions(-) diff --git a/.devcontainer/Dockerfile b/.devcontainer/Dockerfile index 218e1ca6a687..93a1778fe086 100644 --- a/.devcontainer/Dockerfile +++ b/.devcontainer/Dockerfile @@ -9,13 +9,6 @@ RUN apt-get update && apt-get install -y \ unzip \ && rm -rf /var/lib/apt/lists/* -# Set up Node.js (needed for vaadin tests) -RUN curl -fsSL https://deb.nodesource.com/setup_16.x | bash -
