参考Installing Bazel

Bazel是一个编译软件。

1. sudo add-apt-repository ppa:webupd8team/java
2. sudo apt-get update
3. sudo apt-get install oracle-java8-installer
4. echo “deb http://storage.googleapis.com/bazel-apt stable jdk1.8” | sudo tee /etc/apt/sources.list.d/bazel.list
5. curl https://storage.googleapis.com/bazel-apt/doc/apt-key.pub.gpg | sudo apt-key add -
6. sudo apt-get update
   
   • 此时可能出现
     W: 无法下载 http://storage.googleapis.com/bazel-apt/dists/stable/InRelease Unable to find expected entry ‘jdk1.8/binary-i386/Packages’ in Release file (Wrong sources.list entry or malformed file)
     E: Some index files failed to download. They have been ignored, or old ones used instead.
     的错误，解决：
     sudo vim /etc/apt/sources.list.d/bazel.list
     将deb http://storage.googleapis.com/bazel-apt stable jdk1.8修改为deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8

     Software Update fails - Unable to find expected entry
7. sudo apt-get install bazel
8. sudo apt-get upgrade bazel
9. Bazel基本用法
   
   • 参考Getting Started with Bazel
   • 创建/home/majing/workspace/bazel-project目录
   • 在bazel-project目录下创建WORKSPACE空文件
   • mkdir -p src/main/java/com/example
   • cat > src/main/java/com/example/ProjectRunner.java
     << EOF package com.example;
     public class ProjectRunner {
     public static void main(String args[]) {
     Greeting.sayHi();
     }
     }
     EOF
   • cat > src/main/java/com/example/Greeting.java << EOF
     package com.example;
     public class Greeting {
     public static void sayHi() {
     System.out.println(“Hi!”);
     }
     }
     EOF
   • 创建BUILD文件，写入# ~/gitroot/my-project/BUILD
     java_binary(
     name = “my-runner”,
     srcs = glob([“*/.java”]),
     main_class = “com.example.ProjectRunner”,
     )
   • bazel build //:my-runner
   • bazel-bin/my-runner
