1. Build automation with Gradle Using git, gradle and sonarqube for build automation
2. Automate It! Gradle is Open Source Build Automation Tool which natively supports Java/Android/C/C++ builds. Many other languages are supported with plugins. Advantages: - cross platform builds - DevOps Lifecycle integration - Easy dependency management - Programmable builds - High Performance - Build Reports
3. Let’s start with git git init # initializes git repository # create .gitignore git add . # adds changes in local repository to stage git commit -m “Initial commit” # commits staged changes git tag v0.0.0 # signes last commit with label “v0.0.0”
4. Useful git options git checkout v0.0.0 # checkout code to specified tag git tag --list # list all tags git describe --tags # shows last tag (and last commit if has changes) git push <origin> --tags # pushes tags to remote repository
5. Get app versionCode from git // returns current app version code based on number of tags in git // returns -1 if an error occurred def getVersionCodeFromGitTagCount = { -> try { def code = new ByteArrayOutputStream() exec { commandLine 'git', 'tag', '--list' standardOutput = code } return code.toString().split("\n").size() } catch (ignored) { return -1; } }
6. Get app versionName from git // returns current app version name based on last tag in git // returns undefined if an error occurred def getVersionNameFromLastGitTag = { -> try { def stdout = new ByteArrayOutputStream() exec { commandLine 'git', 'describe', '--tags' standardOutput = stdout } return stdout.toString().replaceAll("^v", "").trim() } catch (ignored) { return "undefined"; } }
7. Usage of those functions android { //... defaultConfig { ... versionCode getVersionCodeFromGitTagCount() versionName getVersionNameFromLastGitTag() //... } }
8. Setting apk name format android { applicationVariants.all { variant -> def date = new Date(); def formattedDate = date.format('yyyyMMdd') if (variant.name == "release") { variant.outputs.each { output -> output.outputFile = new File( output.outputFile.parent, "${formattedDate}-MyApp-${variant.versionName}.apk") } } } //... }
9. Setting mapping file name format android { applicationVariants.all { variant -> def date = new Date(); def formattedDate = date.format('yyyyMMdd') variant.outputs.each { output -> if (variant.getBuildType().isMinifyEnabled()) { variant.assemble.doLast { copy { from variant.mappingFile into output.outputFile.parent rename { String fileName -> "${formattedDate}-mapping-${variant.versionName}.txt" } }}}}} //... }
10. Manage Code Quality SonarQube is an open platform to manage code quality. It covers the 7 axes of code quality
11. Installation # install database sudo apt-get -y install mysql-server mysql-client # download and install sonarqube sudo sh -c 'echo deb http://downloads.sourceforge.net/project/sonar-pkg/deb binary/ > /etc/apt/sources.list.d/sonarqube.list' sudo apt-get update sudo apt-get -y --force-yes install sonar sudo update-rc.d sonar defaults # mysql -u root -p mysql > create schema sonar DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; mysql > create user 'sonar'@'%' Identified By 'sonar'; mysql > grant all privileges on sonar.* to sonar; # change configuration in /opt/sonar/conf/sonar.properties (uncomment): sonar.jdbc.username=sonar sonar.jdbc.password=sonar sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar? useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance
12. Back to gradle apply plugin: 'sonar-runner' android { //... sonarRunner { sonarProperties { property "sonar.host.url", SONAR_URL property "sonar.jdbc.url", SONAR_DB_URL property "sonar.jdbc.driverClassName", SONAR_DB_DRIVER property "sonar.jdbc.username", SONAR_USER property "sonar.jdbc.password", SONAR_PASSWORD property "sonar.language", "java" property "sonar.sources", "src" property "sonar.sourceEncoding", "UTF-8" property "sonar.projectKey", android.defaultConfig.applicationId property "sonar.projectName", "My App Name" property "sonar.projectVersion", android.defaultConfig.versionName property "sonar.exclusions", "**Test.java,**IT.java,**Stub.java" } } //... }
13. SonarQube Open http://localhost:9000/ User: admin Password: admin
