Runtime versions in buildspec file sample for CodeBuild

Follow steps 1 and 2 in Create the source code to generate source code. If successful, a directory named my-web-app is created with your source files.

Create a file named buildspec.yml with the following contents. Store the file in the (root directory name)/my-web-app directory.

version: 0.2

phases:
  install:
    runtime-versions:
      java: corretto8
  build:
    commands:
      - java -version
      - mvn package
artifacts:
  files:
    - '**/*'
  base-directory: 'target/my-web-app'

In the buildspec file:

Your file structure should now look like this.

(root directory name)
└── my-web-app
    ├── src
    │   ├── main
    │   ├── resources
    │   └── webapp
    │       └── WEB-INF
    │           └── web.xml
    │               └── index.jsp
    ├── buildspec.yml
    └── pom.xml

Upload the contents of the my-web-app directory to an S3 input bucket or a CodeCommit, GitHub, or Bitbucket repository.

Open the Amazon CodeBuild console at https://console.amazonaws.cn/codesuite/codebuild/home.

Create a build project. For more information, see Create a build project (console) and Run a build (console). Leave all settings at their default values, except for these settings.

Choose Start build.

On Build configuration, accept the defaults, and then choose Start build.

After the build is complete, view the build output on the Build logs tab. You should see output similar to the following:

[Container] Date Time Phase is DOWNLOAD_SOURCE
[Container] Date Time CODEBUILD_SRC_DIR=/codebuild/output/src460614277/src
[Container] Date Time YAML location is /codebuild/output/src460614277/src/buildspec.yml

[Container] Date Time Running command export JDK_HOME="$JDK_8_HOME" 
 
[Container] Date Time Running command for tool_path in "$JAVA_8_HOME"/bin/* "$JRE_8_HOME"/bin/*;

Update the runtime-versions section with Java version 11:

install:
    runtime-versions:
      java: corretto11

After you save the change, run your build again and view the build output. You should see that the installed version of Java is 11. You should see output similar to the following:

[Container] Date Time Phase is DOWNLOAD_SOURCE
[Container] Date Time CODEBUILD_SRC_DIR=/codebuild/output/src460614277/src
[Container] Date Time YAML location is /codebuild/output/src460614277/src/buildspec.yml

Open the Amazon CodeBuild console at https://console.amazonaws.cn/codesuite/codebuild/home.

Create a build project. For more information, see Create a build project (console) and Run a build (console). Leave all settings at their default values, except for these settings.

For Build specifications, choose Insert build commands, and then choose Switch to editor.

In Build commands, replace the placeholder text with the following:

version: 0.2

phases:
  install:
    runtime-versions:
      android: 29
      java: corretto8
  build:
    commands:
      - ./gradlew assembleDebug
artifacts:
  files:
    - app/build/outputs/apk/app-debug.apk

The runtime-versions section specifies both Android version 29 and Java version 8 runtimes.

Choose Create build project.

Choose Start build.

On Build configuration, accept the defaults, and then choose Start build.

After the build is complete, view the build output on the Build logs tab. You should see output similar to the following. It shows that Android version 29 and Java version 8 are installed:

[Container] 2019/05/14 23:21:42 Entering phase DOWNLOAD_SOURCES 
[Container] Date Time Running command echo "Installing Android version 29 ..." 
Installing Android version 29 ... 
 
[Container] Date Time Running command echo "Installing Java version 8 ..." 
Installing Java version 8 ... 

Create a directory named my-source.

Inside the my-source directory, create a directory named golang-app.

Create a file named hello.go with the following contents. Store the file in the golang-app directory.

package main
import "fmt"

func main() {
  fmt.Println("hello world from golang")
  fmt.Println("1+1 =", 1+1)
  fmt.Println("7.0/3.0 =", 7.0/3.0)
  fmt.Println(true && false)
  fmt.Println(true || false)
  fmt.Println(!true)
  fmt.Println("good bye from golang")
}

Inside the my-source directory, create a directory named nodejs-app. It should be at the same level as the golang-app directory.

Create a file named index.js with the following contents. Store the file in the nodejs-app directory.

console.log("hello world from nodejs");
console.log("1+1 =" + (1+1));
console.log("7.0/3.0 =" + 7.0/3.0);
console.log(true && false);
console.log(true || false);
console.log(!true);
console.log("good bye from nodejs");

Create a file named package.json with the following contents. Store the file in the nodejs-app directory.

{
  "name": "mycompany-app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"run some tests here\""
  },
  "author": "",
  "license": "ISC"
}

Create a file named buildspec.yml with the following contents. Store the file in the my-source directory, at the same level as the nodejs-app and golang-app directories. The runtime-versions section specifies the Node.js version 12 and Go version 1.13 runtimes.

version: 0.2

phases:
  install:
    runtime-versions:
      golang: 1.13
      nodejs: 12
  build:
    commands:
      - echo Building the Go code...
      - cd $CODEBUILD_SRC_DIR/golang-app
      - go build hello.go 
      - echo Building the Node code...
      - cd $CODEBUILD_SRC_DIR/nodejs-app
      - npm run test
artifacts:
  secondary-artifacts:
    golang_artifacts:
      base-directory: golang-app
      files:
        - hello
    nodejs_artifacts:
      base-directory: nodejs-app
      files:
        - index.js
        - package.json

Your file structure should now look like this.

my-source
├── golang-app
│   └── hello.go
├── nodejs.app
│   ├── index.js
│   └── package.json
└── buildspec.yml

Upload the contents of the my-source directory to an S3 input bucket or a CodeCommit, GitHub, or Bitbucket repository.

Open the Amazon CodeBuild console at https://console.amazonaws.cn/codesuite/codebuild/home.

Create a build project. For more information, see Create a build project (console) and Run a build (console). Leave all settings at their default values, except for these settings.

Choose Create build project.

Choose Start build.

On Build configuration, accept the defaults, and then choose Start build.

After the build is complete, view the build output on the Build logs tab. You should see output similar to the following. It shows output from the Go and Node.js runtimes. It also shows output from the Go and Node.js applications.
