重建DSpace更新站点语言时遭遇Maven构建失败求助

Hey there, let's work through this DSpace Mirage2 build failure together. You're hitting two linked issues: an unavailable rubygems proxy service and an outdated Ruby version that doesn't meet the rb-inotify gem's requirements. Here's how to resolve both:

Step 1: Upgrade Your Ruby Version #

Ubuntu 16.04 ships with a Ruby version older than 2.2, which is required for rb-inotify-0.10.0.gem. We'll use rbenv (a lightweight Ruby version manager) to install a compatible version:

• First, install dependencies for building Ruby:

  sudo apt-get install git curl libssl-dev libreadline-dev zlib1g-dev
  

• Clone rbenv to your user directory:

  git clone https://github.com/rbenv/rbenv.git ~/.rbenv
  

• Add rbenv to your shell's PATH (for Bash):

  echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
  echo 'eval "$(rbenv init -)"' >> ~/.bashrc
  

  If you use Zsh, replace .bashrc with .zshrc in the commands above.
• Reload your shell to apply the changes:

  source ~/.bashrc
  

• Install the ruby-build plugin to simplify Ruby version installation:

  git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
  

• Install a Ruby version ≥2.2 (we'll use 2.7.8, a stable, widely compatible release):

  rbenv install 2.7.8
  

• Set this as your global default Ruby version:

  rbenv global 2.7.8
  

• Verify the upgrade worked:

  ruby -v
  

  You should see output like ruby 2.7.8p225 (2023-03-30 revision 1f4d455848) [x86_64-linux].

Alternative for apt users: If you prefer system packages, use the Brightbox Ruby PPA:

sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt-get update
sudo apt-get install ruby2.7 ruby2.7-dev

Step 2: Fix the Rubygems Proxy 503 Error #

The rubygems-proxy.torquebox.org service is unreliable (returning 503 errors). Let's switch to the official rubygems source:

• Remove the problematic proxy source:

  gem sources --remove https://rubygems-proxy.torquebox.org/
  

• Add the official rubygems source:

  gem sources --add https://rubygems.org/
  

• Confirm only the official source is listed:

  gem sources -l
  

• Install or update Bundler (used by Mirage2 to manage gems):

  gem install bundler
  

Step 3: Re-Run the DSpace Build #

Clear cached artifacts to avoid leftover issues before rebuilding:

• Navigate to your DSpace source directory.
• Clean Maven's build cache:

  mvn clean
  

• Navigate to the Mirage2 theme directory and clean Ruby gem caches:

  cd xmlui/src/main/webapp/themes/Mirage2
  bundle clean --force
  bundle install
  

• Return to the root DSpace directory and run your original build command:

  cd ../../../../../
  mvn -U clean package -Dmirage2.on=true
  

This should resolve both the Ruby version mismatch and the rubygems proxy error, letting the Mirage2 theme build successfully.
