Installing Bazel on Ubuntu
Using Bazel custom APT repository (recommended)
1. Install JDK 8
Install JDK 8 by using:
sudo apt-get install openjdk-8-jdk
On Ubuntu 14.04 LTS you'll have to use a PPA:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update && sudo apt-get install oracle-java8-installer
2. Add Bazel distribution URI as a package source (one time setup)
echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list
curl https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -
If you want to install the testing version of Bazel, replace stable with testing.
3. Install and update Bazel
sudo apt-get update && sudo apt-get install bazel
Once installed, you can upgrade to a newer version of Bazel with:
sudo apt-get upgrade bazel
