Cleanup Older XCodes

Note: The /Applications Volume seems to have slow I/O. So it will take much time to delete them.

Some XCode is outdated in macOS VM in GitHub Actions, so it needs to be cleaned and updated.

cd /System/Volumes/Data/Applications/
{
  echo "will cite" | parallel --citation
} &>/dev/null
USED_XCODE=$(ls -lAog Xcode.app | awk -F'/' '{print $NF}')
for i in Xcode_10*.app Xcode_11*.app Xcode_12*.app; do
  if [ $i != "$USED_XCODE" ]; then
    printf "Removing %s...\n" "$i"
    parallel --use-cpus-instead-of-cores --jobs 200% sudo rm -rf {} ::: ${i}/Contents/Developer/Platforms/*
    parallel --use-cpus-instead-of-cores --jobs 200% sudo rm -rf {} ::: ${i}/Contents/*
    sudo rm -rf ${i}
  fi
done

Cleanup Mono & Xamarin Frameworks and Visual Studio

Cleanup CoreSimulator Caches

Fix_MacOS_SDKs.md

Fix MacOSX-SDKs

Older macOS SDKs might be needed for build, so we download them inside latest XCode.

cd /System/Volumes/Data/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
for i in 10 11 12 13 14 15; do
  printf "Fetching MacOSX10.%s SDK...\n" "$i"
  aria2c -x8 -s16 --console-log-level=warn --summary-interval=0 --check-certificate=false "https://github.com/phracker/MacOSX-SDKs/releases/download/11.0-11.1/MacOSX10.$i.sdk.tar.xz"
  printf "Placing MacOSX10.%s.sdk...\n" "$i"
  tar xJf MacOSX10.$i.sdk.tar.xz
  rm -f MacOSX10.$i.sdk.tar.xz
done

Install_GNU_Utils.md

Mandatory: Install GNU Utils to replace macOS tools

Install_OpenJDK8.md

Optional: Install openjdk and ccache

brew install openjdk@8
sudo ln -sfn /usr/local/opt/openjdk@8/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-8.jdk
export PATH="/usr/local/opt/openjdk@8/bin:$PATH"
# We are setting 12 out of 14 gigabytes of ram for java heap
export JAVA_OPTS=" -Xmx12G "

brew install ccache
export PATH="/usr/local/opt/ccache/libexec:$PATH"

Setting_Up_Environment.md

Setting Up Build Environment on macOS in SSH

# Create Case-sensitive SPARSE filesystem, we are creating a filesystem image of 220 gigabytes
sudo hdiutil create -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size 220g ~/android.dmg.sparseimage

# Mount the android file image
sudo hdiutil attach ~/android.dmg.sparseimage -mountpoint /Volumes/android

Prepare Repo

# Change Directory to android volume
cd /Volumes/android

# Download repo binary
mkdir -p ~/bin 2>/dev/null
export PATH="~/bin:/usr/local/bin:$PATH"
curl -sL https://gerrit.googlesource.com/git-repo/+/refs/heads/stable/repo?format=TEXT | base64 --decode > ~/bin/repo
chmod a+x ~/bin/repo

# Set git config for authorizing repo, Use your github email address and name
git config --global user.email ${GitHubMail}
git config --global user.name ${GitHubName}
git config --global color.ui true

Repo Init and Sync and Beyond

# Choose your repo manifest (Example: AOSP master branch, shallow)
repo init -u https://android.googlesource.com/platform/manifest --depth=1

# Sync it, make sure to minimize outputs here and while building rom
# We are using 6 parallel threads for syncing
repo sync -c -q --force-sync --no-clone-bundle --no-tags -j6

Build

Well, you know the rest commands.

SSH_KeepAlive.md

Keepalive SSH Sessions

Run and add this snippet into the Server before you enter into it. It will try to keep your session alive all the time.
