Scala Jenkins agent
Introduction
This agent is used to build Scala code through SBT (Scala build tool).
The image is built in the global ods project and is named jenkins-agent-scala.
It can be referenced in a Jenkinsfile with ods/jenkins-agent-scala.
Supported Java Versions
This agent provides 1 JDKs: java 11 and java 17 (default).
For backwards compatibility java 11 is till included. Java projects migrating from previous ODS version will require the use of the bash script use-j11.sh to use java 11. A migration to java 17 can be done afterwards.
To switch the environment to java 11 the script use-j11.sh is provided at the jenkins home folder.
To switch the environment to java 17 the script use-j17.sh is provided at the jenkins home folder.
Following command shows how the jenkins build script from the scala quickstarter switches the java version before calling the SBT:
def status = sh(script: "$HOME/use-j11.sh && sbt -v clean scalafmtSbtCheck scalafmtCheckAll coverage test coverageReport coverageOff compile:clean copyDockerFiles && $HOME/use-j17.sh", returnStatus: true)
like this example, you will need to switch back to java 17 after running the SBT build. This is required because the scala agent environment still does not support the latest java version. E.g. the sonar scanner is not compatible with the java 11.
